Simplifying the IUID marking process

uid2go — Wed, 25 Nov 2009 09:18:14 +0100

The purpose of IUID marking

IUID marking is the marking of an item's unique identification. As per MIL STD 130, the Department of Defense requires that many items be assigned an IUID marking in order to mark, identify, and track the military property effectively. MIL STD 130 consolidates the different specifications and standards which are involved in the creation of the IUID marking. In any conflicts between MIL STD 130 and other documentation, regarding IUID marking or any other stated guidelines, MIL STD 130 takes complete precedence. Some items, such as cell phones and automobiles, are considered non IUID items as they have their own identification numbers already assigned to them by their respective manufacturers.

How should the IUID be marked?

The IUID marking is to be either directly on the item or on a stiff metal band attached to the item. If at all possible, the IUID should be visible whenever the item is used in normal operation, and the marking must be able to remain legible after any necessary cleaning and rebuilding, for the life of the item. Unless deemed impossible due to lack of space or other reasons, the IUID must be a MRI (machine readable identification). If there is not room for the complete IUID, the more essential data should be shown instead. There are many different industry specific guidelines, and several guidelines regarding font and text size are also included in MIL STD 130.

What all should the IUID contain?

Depending on the construct used for the IUID, there may be different pieces of data required to be included. Both constructs require the serial number as well as the EID of the activity assigning the serial number. Certain specifications also apply regarding the marking of the item's PIN number, and procedures to be followed should the PIN number be changed.

Should the MRI include anything other than the IUID?

In addition to the IUID, the MRI must be updated with any repair or maintenance performed, as well as any data regarding dates of repair of the item, facilities at which the repair took place, updates or extensions to any warranties, and other information as well. The arrangement of the numbers in the MRI is specific so as to allow the IUID marking to be read by machines. Other guidelines involve the quality of the marking as well as the amount of data required to be contained in the MRI.

Simplifying IUID marking

This is but a brief overview of all that is included in MIL STD 130 in reference to IUID marking. The experts at Jet City Laser know all of the details and can assist in applying the correct IUID marking as per MIL STD 130, as well as any other pertinent guidelines, changes, or updates to the IUID marking procedures.

MIL STD 130 A Standard Protocol For Uniq...

uid2go — Wed, 18 Nov 2009 08:41:29 +0100

The MIL STD 130 is a protocol followed by the Department of Defense for keeping track of their military property. This property includes anything produced stocked stored or issued by and for the DoD. Ultimately this MIL STD 130 standard is a guideline to be used when determining the minimum needs of the government for a specific contract. If there are any conflicts between this standard and any reference documents, the standard will always take precedence.

Jet City Laser is a leading technical company which has specialized in product marking and identification systems for the MIL STD 130. Items under the control of the DoD have to be properly marked. These marks are required to be applied to an I.D. plate, band, tag or label. These plates can be made of metal or a stiff plastic material and must be securely fastened to the item or applied directly to the item itself.

The MIL STD 130 standard also requires the marking to be placed somewhere on the item where it is visible and can be easily read. The marking also has to be permanent, lasting the life of the item. These markings are referred to as Item Unique Identification or IUID. Sometimes these markings are made using a machine readable information (MRI) marking. The markings must also adhere to a list of standards including text size, acceptable fonts as well as MRI marking protocol to be used. The list of Industry Specific Protocols when marking products is lengthy at best. For more in depth information regarding these protocols and the MIL STD 130, contact Jet City Laser.

The MIL STD 130 states that when the DoD works with NASA, NASA's marking standards will be used. This is one of the few instances where MIL STD 130 does not take precedence.

The MRI marking system gives specific instructions as to how an item is to be marked. It also sets up guidelines for the minimum amount of information that can be contained on the mark. This depends on what type of item is being marked, whether it is IUID or non-IUID. Some items are exempt from these requirements, such as Commercial Off The Shelf (COTS) items as well as some Legacy items.

There are also specifications within MIL STD 130 for the quality of the item markings. These include protocols for bar codes as well as data matrix symbols. A number of protocols can be used when measuring a data matrix symbol's quality, all at the supplier's discretion. Marking arrangements are made based on the manufacturer of the item.

The MIL STD 130 is complex and often difficult to understand. If you have any questions, you can contact Jet City Laser to find the right answers.

Basic Background Information Regarding M...

uid2go — Mon, 02 Nov 2009 09:17:50 +0100

The Department of Defense (DoD) established MIL-STD-130 which defines certain standard requirements for labeling and identifying all hardware articles; whether it's a discrete single item or single units comprising a group of subassemblies, components or parts. This standard specifically addresses the requirements of the U.S. Military; and, it mandates all hardware be uniquely identifiable by the application of a label marked with machine-readable characters or numbers which distinguishes any item from every other item, regardless of similarity or difference. MIL-STD-130 is the generic term referencing the standard; iterations and changes which significantly alter MIL-STD-130 are denoted by a suffix appended to the basic standard. For example, MIL-STD-130N superseded MIL-STD-130M.

As with any MIL-STD document, it is by the nature of its subject matter, necessarily complex and detailed. Any item of military property which is produced, stocked, stored, or issued by DoD must be marked in accordance with MIL-STD-130. It's the responsibility of the manufacturer or contractor to ensure compliance with the marking requirements and methods for human-readable and machine-readable information (MRI) label content.

MIL-STD-130 is a dynamic standard in the sense that it's constantly being refined to include the latest available marking, labeling, and identification technologies and eliminate deprecating methodologies and identify methods which have been overtaken by events or superseded by other specifications.

All equipment defined as an item by MIL-STD-130 must have a Unique Identifier (UID). Because of the potential of confusion with the three letter acronym, it is more commonly referred to as an Item Unique Identifier (IUID).

Certain items – such as disposable or limited life items, e.g., non-rechargeable batteries – may not require an IUID. Other items that already have a unique identifier; e.g., manufactured motor vehicles. This does not preclude the necessity of the item requiring supplemental identification to make it compliant with MRI technologies.

This standard specifies that some legacy items also be marked. MIL-STD-130 mandates coordination with the organization or activity – referred to collectively as Enterprise Identifiers, each with a unique EID.

The defense contractor or end-item provider is well-served by using a qualified subject matter expert. The level of expertise and experience required to determine that the item is correctly and accurately labeled in accordance with MIL-STD-130 is a non-trivial task. The best solution to ensure compliance with MIL-STD-130 is to use the services of a corporation in the business of manufacturing conforming labels and tags with a known track record of meeting or exceeding the standards mandated by MIL-STD-130. It is especially advantageous to use a company which is an acknowledged subject matter expert that directly contributed to the specifications which became the current iteration of MIL-STD-130. Due to the complexity of the subject matter, please contact the experts at Jet City Laser for more information.

Jet City and ID - Integration Meet MIL-S...

uid2go — Mon, 26 Oct 2009 13:12:36 +0100

The United States Department of Defense's standard MIL-STD-130 encompasses specific standards mandated by the Department of Defense with regard to identifying, marking and maintaining accurate records of military property. All government contractors must comply with MIL-STD-130 regulations, which require that certain products be properly labeled with a Unique Identifier (IUID marking).

The IUID marking requirement stipulates that mandated items be labeled with a machine readable 2 dimensional data matrix bar code. Regardless of their composition, all items must meet specific printing and/or marking specifications. In addition, items subject to IUID marking must adhere to stringent specifications. Specifications require that all marking must be applied to either a stiff plastic or metal identification plate, and contain an identification tag, band or label. IUID marking must also be located where it is clearly visible and easily read, and markings must be permanent and impervious to normal environmental conditions.

IUID markings are composed of character strings, numbers, or sequential bits that are unique to the product being labeled. IUID marking regulations are rigorous, and must include details of the product’s geographic location, product size, serial number, agency code, a personal identification number and both contract and order numbers. Moreover, the specified data must be globally unique.

The IUID marking policy was established to improve asset management, lower the cost of item management, improve inventory management, improve item availability and provide the DoD with the ability to conduct concise audits. The standard is also used as a guide to ascertain governmental needs when designing specific contracts.

Through their expert input, Jet City Laser, experienced distributors of marking and reading technologies since 1994, provided the DoD with invaluable assistance in the development of Unique Identification techniques. Jet City Laser offers an ironclad guarantee on all of their products, including 100% verification that their nameplates and labels meet MIL-STD-130 requirements as well as a 100% guarantee that all product data is archived for future reference.

UID Nameplates – DoD’s Way of Uniquely I...

uid2go — Wed, 21 Oct 2009 12:06:12 +0200

Imagine being one of the people responsible for the supplies procured by the US Armed Services. What sorts of supplies does the Department of Defense (DoD) have to track on a daily basis? Consider the sheer number of uniforms, boots, packs, helmets, hats, patches, belt buckles, and boxed goods the military must keep track of. Besides these items, the DoD must track its weapons, ammunition, and other highly sensitive materials. At any given time, as a matter of national security, the military must know where these items are, how many they have, and that the items comply with DoD standards. How do they do it?

To facilitate the tracking of their supplies, the military has developed a set of standards known as Mil Specs, or MIL-STD. Within these standards, there exists a specific standard known as MIL-STD-130N, which outlines how the military is to mark, identify, and track military property.

Each item of military property is marked with UID nameplates, tags, or labels to identify it. UID is a more generic term that refers generally to the “Government Program of Uniquely Identifying Items”. An IUID is the “item unique identifier”, and refers to the actual number or character string that an item is stamped with to identify it. UID nameplates, then, are nameplates attached to a given item that has a barcode or similar computerized code that is used to track that particular piece of property. In some ways, UID nameplates are not different than the barcodes placed on consumer goods used to track retail inventory. In other ways, UID nameplates are vastly different.

Basic Rules for UID Nameplates, Labels, and Tags

According to MIL-STD-130N, UID nameplates, labels, or tags should be placed in a location where they will be visible and easy to read. Furthermore, the IUID must be placed on stiff plastic or metal, making the UID nameplates more durable and resistant to damage that would prevent its code from being machine-readable. Given that the item may be shipped, roughly handled, or exposed to variations in temperature, the UID nameplates must be able to withstand various environmental conditions.

To make UID nameplates easily readable, recommended nameplate or label size for text is 0.2 cm, 0.08 in, or 5.76 pts. To comply with the MIL-STD-130N, all text on UID nameplates must be in a san-serif font, which includes but is not limited to Arial, Trebuchet, and Futura. Additionally, to keep the size of UID nameplates reasonably small, the amount of text is limited to 50 characters.

Don't Rely Upon an Amateur Understanding

As can be seen from the brief outline of MIL-STD-130N above, correctly creating and implementing UID nameplates, labels, and tags is not simple. To be in compliance with all the Mil Specs, it is wise to turn to the experts at Jet City Laser, who have years of experience working within the boundaries of these standards.

UID Registry – A Helping Aid In The Armo...

uid2go — Wed, 14 Oct 2009 13:52:50 +0200

Everyone who has purchased items from a military surplus or otherwise done business with the department of defense is well familiar with UID numbers, also known as "Unique Item Identifier." This combination of numbers and letters is a unique identifier which is attached to each particular item that the military may purchase or need. While somewhat complicated, this allows the department of defense to instantly track the usage of everything from bullets to gasoline to toilet paper, and expedites the requisition of items. In use for decades, the UID is designed to be small and simple enough to quickly be applied to almost any item (or at least the box that it comes in) and in most cases can even be accompanied by a bar code to facilitate efficient invoicing. After all, good logistics is essential to any war effort, and many battles have been lost for want of supplies.

In an effort to keep this technology up to date and enable the Department of Defense to have the best logistics possible, Jet City Laser helped to develop the current model of this technology. The current model revolves around a UID registry which keeps a complete record of what's available and in what quantity. Jet City Laser has many years of experience in product marking and identification systems, so they were a natural choice to enhance the UID registry with the new MIL-STD-130.

The MIL-STD-130 standard is mandated for all UID items. It dictates what sort of number is assigned to each item. Jet City Laser has ensured that these numbers follow a smart and logical pattern in order to make the UID registry as simple to use and helpful. Jet City Laser has many years of experience with ID integration, so coming up with good ID systems with lots of room for as-of-yet unincluded items so the MIL-STD-130 numerical systems they helped to develop are easy to use both by civilians and military users. While not all inclusive (other ID systems are also used) it is very popular and known for it's reliability.

The trick to maintaining a good UID registry is to ensure that the MIL-STD-130 number is in a place where it is easily visible, yet quite permanent. This is where Jet City Laser's expertise has come in most helpful. Their advanced technology has allowed for the best sort of permanent labeling, with different methods and labels for each item. Advanced technology is necessary to ensure that these labels remain readable even under harsh conditions. The markings also need to not be too small so that they are readable for proper inventory and maintenance of the UID registry. Jet City Laser's experience in the world of advanced labeling ensured that they were able to develop labels that are up to the task.

IUID - Uniquely Identifying US Military...

uid2go — Thu, 08 Oct 2009 10:10:19 +0200

If you are an end item equipment manufacturer that produces an article for sale or resale to the U.S.   military, you need your equipment to be in compliance with the specifications and standards defined by MIL-STD-130N. This is the latest iteration of the   long-established MIL-STD-130 which contains the changes additions and modifications pertaining to the use of Item Unique   Identifiers (IUID) to mark items used by the military.

The IUID comprises a number of specific elements, when   used combine to make every item – regardless of similarity or difference – completely unique. Portions of the IUID are machine-readable identifiers (MRI). These include bar codes in several   formats, 2D data matrix elements in two formats, and standardized fonts and type styles which may be machine readable,   although that is not the primary use of alphanumeric designators. Human-readable Identification (HRI) includes alphanumeric   data distinguishing one item from another. This also includes Free Text, which is usually a description or common name of the   article for convenience purposes. The IUID, when used in routine conversation or when referring to the name plate, tag or   other marking is generally seen as “the UID” as a convenience. Because of potential ambiguity or confusion with the use of   the UID acronym, it is referred to formally as the IUID.

There are a number of discrete elements which are   concatenated to form a Unique Item Identifier. Among the elements which are displayed on the name tag, ID plate, data plate   or similar generic term for an IUID, are Text Element Identifier (TEI), Part   Identification Number (PIN), Enterprise Identifier (EID), and provisions for other refinements which may be used for future   applications.

The days of an item being identifiable by make/model and serial number are gone. As a point of   fact, some legacy equipment is required to be assigned a UII and have an IUID data plate affixed to the item.

The defense contractor or end-item provider is generally not equipped or prepared to manufacture ready-to-install IUID   plates. Standards are modified and technology changes constantly and it is a daunting task to conform with mandated changes.   By using a qualified subject matter expert and using third-party IUID plates and tags that are guaranteed compliant, the   contractor can concentrate on manufacturing their specific items.

The best solution is to use the services of a   corporation in the business of manufacturing conforming IUID   labels and tags with a tested and proven track record of meeting or exceeding the standards mandated by MIL-STD-130.   It is good business to use a company which is an acknowledged subject matter expert that directly contributed to the   specifications in the current iteration of MIL-STD-130. Due to the complexity of the subject matter, please contact the   experts at Jet City Laser for more information.

Ensure UID Marking Compliance by Trustin...

uid2go — Wed, 07 Oct 2009 06:51:11 +0200

The United States Department of Defense (DoD) MIL-STD-130 standard for Unique Identification (UID) marking has been established in order to allow for optimized asset, inventory and accounting tracking and control. The DoD has created detailed guidelines for product printing and marking for its tangible assets located around the world. It can quickly compile information collected from these identification codes for use in its centralized database. All government contractors must comply with these DoD standards when selling products to the military.

Basic UID marking parameters include unique identification numbers, bar codes and a 2D Data Matrix symbol. This combination of human-readable and machine-readable marking is used for the rapid accumulation of asset management information on physical military resources. This data can then be modified by military staff.

UID Marking Techniques

The military uses a wide variety of products, made of different material (paper, rubber and metal). Some products can be written on; others need specially made nameplates, labels and tags for quick identification. The DoD has established different UID marking standards for each of these product materials.

The DoD has established quality guidelines for each of the most prominent UID marking techniques: laser, mechanical engraving, chemical etching, ink jet, paint and epoxy base. The DoD demands high levels of legibility and durability in UID marking – the free text and symbols must withstand hazardous chemicals, inclement weather, natural decay and extreme temperature changes.

UID Marking Specifications

The DoD recognizes that because its products have different sizes and shapes, they require different UID marking standards. Many of these UID marking labels consist of multiple bar codes, identification numbers and 2D Data Matrix identification marks. The DoD has set up “preferred” labeling standards for optimum legibility and content; alongside alternate guidelines (when labeling space is more limited). Location and lettering type for the UID marking is also specified by the DoD.

Another variation in UID marking is found in the two constructs:
Construct One - Issuing Agency Code (IAC), Part Number and Traceable Number combined into one UID

Construct Two - Issuing Agency Code (IAC), Lot or Batch Number, Part Number and Traceable Number combined into one UID

Different labels are also regulated separately: Free text, Air Transport Association (ATA) and Consumer Electronics Association (CEA), for example. The UID marking for products sold to the military must be designed to specified requirements, which are continually being updated.

Ensure that you have top-notch quality assurance for your product labels, that fulfills DoD compliance regulations for UID marking and identification systems. The experts will read all of the important manuals and maintain the high standards you expect. UID marking is a complicated issue; so turn to the experts at Jet City Laser to help you comply with these standards.

An Overview of the Significant Changes o...

uid2go — Thu, 24 Sep 2009 09:16:37 +0200

MIL-STD-130N is the current iteration of the set of military standards mandated by the Department of Defense (DoD) which establishes the criteria for the identification, marking or tagging all U.S. military equipment with an Item Unique Identification (IUID, occasionally seen as UID). MIL-STD-130N supersedes MIL-STD-130M and establishes the precedence of MIL-STD-130N, excepting applicable laws or regulations, unless specifically exempted.

There are many significant additions, medications, and clarification of ambiguous content contained in previous iterations of MIL-STD-130. In order to ensure compliance with current requirements, it is necessary and required to have a sound technical understanding of the standard and its application to articles and items needing appropriate identification and proper use of marking and tagging technologies.

Of particular interest in MIL-STD-130N are the definition of an Application Identifier (AI); the establishment of a Data Identifier (DI); expansion of the Human Readable Information (HRI) and its relationship to Machine-Readable Information (MRI); the establishment of the IUID-equivalent and the exemption of items which already have other unique identification codes; and, a more detailed description of specific elements of the IUID.

Other portions of MIL-STD-130N of special interest are the requirements for labeling and marking supplemental containers of identified equipment. The issues of permanency and human legibility are also further refined. Construction and durability of tags as well as MRI identification are amplified with references to documents establishing standards incorporated by specific definition. Data carriers, especially MRI formats are more detailed. Linear bar codes and 2D data matrix markings are clarified.

MIL-STD-130N also signals the deprecating feature of the old part identification and the superseding new IUID with the specification of two label designs: Construct #1 and Construct #2. Guidance for the obliteration and replacement of the two different constructs is specifically addressed in MIL-STD-130N

MIL-STD-130N has a completely revamped and enhanced the data tables; and, worthy of note, has replaced diagrams and figures to incorporate the changes and provide strong visual guidance for the use of Free Text, HRI, and MRI to include bar codes and 2D data matrix elements.

The defense contractor or end-item provider should consult a qualified subject matter expert. The level of expertise and experience required to stay in compliance with the changes set forth in MIL-STD-130N is a non-trivial task. It is required to label and tag U.S. military items in accordance with MIL-STD-130N. Retaining the services of a corporation with an established reputation in the business of manufacturing conforming labels and tags which meet or exceed the standards mandated by MIL-STD-130N cannot be over-emphasized. Choose a company which is an acknowledged subject matter expert that directly contributed to the specifications contained in MIL-STD-130N. Due to the complexity of the subject matter, please contact the experts at Jet City Laser for more information.

UID Labels as Standardized by MIL-STD-13...

uid2go — Wed, 16 Sep 2009 09:36:40 +0200

Unique Identification Labels or UID Labels are used by the Department of Defense (DoD) in order to keep track of every piece of military property within their possession. MIL-STD-130 is the standard by which those items are marked. Jet City Laser was instrumental in the development of MIL-STD-130 which aides the government by specifying which items need UID Labels, as well as how and where they should be identified.

MIL-STD-130 requires that UID Labels are visible and can withstand normal environmental conditions throughout the life expectancy of the item. Most commonly, MRI (Machine Readable Information) will be used, however, some conditions require a less permanent UID Label and sometimes only essential information is marked such as the manufacturer’s EID (Enterprise Identifier) and the PIN, LOT, or batch number of the item. In addition, in the rare situation that there is no space available to place the MIL-STD-130 standardized UID Label, the mark is placed on the packaging. When MRI is inaccessible, there are separate requirements mandating the type and size of font to be used for all characters. UID Label protocols are further specified by various orders.

As is expected, there are exceptions to the MRI marking routine. COTS (Commercial Off The Shelf) items that are clearly marked with some sort of commercial identification may be exempt from UID Labels as long it will not result in identification difficulties. Individual parts may also be exempt from MRI UID Labels if they are not expected to be removed, repaired, or replaced. There are other circumstances, such as the UID labeling of a legacy item, that can merit exceptions.

There are other specifications regarding the required marking quality of an MRI:
-Linear Bar Code: ISO/IEC 15416 is the protocol for measuring the print quality of a linear bar code, unless otherwise specified in the contract or order.
-Data Matrix Symbol: Several protocols are available for measuring the print quality of a data matrix symbol that can be used at the supplier's discretion. Those protocols include: ISO/IEC 15415, AIM DPM-1-2006, or SAE AS9132. There are also specifications to be followed if a symbol is unacceptable for any reason.
-Marking Arrangements: Depending on the manufacturer's role in the designing and creation of the item, there are guidelines for the arrangement of the marking on the UID Label. Free text markings for units, groups, and sets are arranged by precise standards as well. All maintenance actions also require additional markings be added to the UID Label.

The DoD requires strict adherence to the guidelines and specifications set out in MIL-STD-130. Thankfully, these complex instructions have human handbooks, Jet City laser experts. A technical company that specializes in product marking and identification systems is best suited for providing essential information and support.

Pros and Cons of Different Direct Part M...

uid2go — Wed, 09 Sep 2009 04:33:43 +0200

There are different types of direct marking methods and the pros and cons of each method are discussed in the articles.

The direct part marking process that has become popular for its numerous advantages can be applied to the items by several different methods. Each method of DPM has its own benefit and requirement depending on the type of item and its functionality. The contractors or the suppliers who are in charge of the items and who are responsible for marking the items with UID need to select the method depending on the type of material for marking, the implementation of marking cost and the reading technology.

The basic types of direct part marking are the intrusive and the non-intrusive marking methods. With the intrusive marking method, there is a direct contact between the surface of the item for marking and the marking device. On the other hand, the non-intrusive direct part marking method doesn’t require such contact. Different types of direct part marking include grooving, engraving, burning, etching and painting.

Grooving

It is one of the intrusive types of DPM and otherwise known as “Dot Peening”. In this method the codes of the UID are grooved on the surface of the item by using a hard head of a marking machine. The device prints the codes by striking the surface subsequently. The advantages of the making procedure are low implementation and operating cost, manual or computer regulation, grooving alphanumeric characters as well as 2D data matrix code, small and convenient grooving device. The down side is that it cannot be applied on any surfaces and is more time-consuming than the laser marking.

Engraving

This is also an intrusive method of direct part marking in which the characters of the codes are directly engraved on the surface of the item or parts. Generally, a metal object is preferred for this marking procedure. The advantages of the methods include low implementation and medium operating costs. The devices are computer controlled or manually handled, and hence, can be used at assembly line. The device used for the method is small and can engrave one dimensional barcodes, trademarks and alphanumeric characters. The shortcomings of the method are it can’t be applied on any surface, its quite time –consuming and it can’t mark 2 dimensional barcode symbols.

Laser Burning

This process of Direct part marking involves use of laser beam to mark the surface of the item to be marked. The benefits of laser burning is that it can produce high quality legibility of the codes, minimum size of the codes on a small surface, assure durability, cost effective operation prices, faster marking. It can be used on any surface and produce UID marking for the items. However, it has its own share of disadvantages. The marking machine used for this is bigger and the implementation cost of the method is comparatively high.

Etching

Etching involves chemical solutions and specific matrix to mark the items and parts with UID. The prime benefit of the method is its durability. The disadvantages are its high operating costs and long operation time. The barcodes produced in this method can’t be machine made or automatic.

Painting

A specific kind of ink is used to put the marks on the surface by painting method. However, marking speed is the noteworthy benefit of the method. This method can’t assure durability of the code.

MIL-STD-130 Spec - A Standard aide for U...

uid2go — Tue, 01 Sep 2009 08:38:20 +0200

The UID marking requirements of the items are specified and defined by the MIL-STD-130 spec for enhanced item marking solution.

The Department of Defense has mandated that the all the UID qualifying items should be marked with UID as per the requirements of the MIL-STD-130 spec. The specifications mentioned in the standard states that all the new procurements as well as the legacy items should be marked with 2D data matrix barcode symbols. The symbol or the markings are either etched on the item and parts directly or marked on a UID nameplate or label which is affixed to the item. Basically, the MIL-STD-130 spec is about the UID marking of the items and defines every aspects of the UID marking.

UID Marking Requirements According to MIL-STD-130 Spec

The DoD requires that the UID marking of the items should be permanent for the functional lifetime of each item. It should be able to withstand the adverse working condition of the item and any chemical processing. Hence, the contractors of the suppliers have to take particular care about the methods that they chose for UID marking to meet the UID standard.

Whether the UID of the item is marked directly on the item or through the nameplates, the MIL-STD-130 spec has mentioned that the marking shouldn’t harm the item or its performance. The marking technologies and the metals of the nameplates should be decided carefully to ensure that the item functionality is not affected.

UID Marking Procedure According to MIL-STD-130 Spec

Although the prime requirement of UID marking is to mark all the UID qualified DoD items with machine readable 2D data matrix barcode symbols, there are other marking specifications mentioned in the standard. It is essential that the length of the UID code shouldn’t exceed 50 characters to comply with the ISO/IEC 15459-4. The font of the letters entered as the code may be Futura, Trebuchet MS, Arial, Gothic, or any other sans-serif fonts, but they should be capitals. In case of printing the numerals, the Roman numerals are applied when designated by the Government standard or applicable industry. Otherwise, the numerals are imprinted in Arabic fonts.

The MIL-STD-130 spec has mentioned different formats of marking different data elements such as Format 05 for Application Identifiers (AI), Format 06 for Data Identifiers (DI), Format 12 for Text Element Identifiers (TEI). The ISO/IEC 16022 requires that the item identification should be marked with Data Matrix ECC200 symbols.

The size of the modules shouldn’t be more than 0.025 inch and less than 0.0075 inch. And, the size of the module should not exceed 1 inch if it is a square symbol. The ratio between the narrow elements and wide elements can range from 2.1:1 to 3.1:1.

The Minimum Print Quality According to MIL-STD-130 Spec

There is a minimum print quality of the 2D data matrix symbols as well as linear barcode. The minimum grade for the linear barcode is 3.0. it is measured with a 0.005 inch aperture that has a 660nm light source wavelength. For the Data Matrix symbols the minimum quality is measured with an aperture of 0.005 inch and 650 nm ± 20 nm light source wavelength.

It is required that the DoD contractors need to follow the instructions and the MIL-STD-130 spec to produce quality UID marking solutions.

Marking of UID labels is an important part of DoD’s item tracking process. The knowledge of UID label marking requirements will produce better marking solutions.

The UID labels are the perfect marking solution for the items that are not suitable for direct part marking. But, UID marking requires meet the UID standard to maintain a balance between markings of different items. Department of Defense has mandated that the item marking should comply with the standards of MIL-STD-130 and the contractors need to take care of each criteria of UID marking for marking the items. The maintenance of technical documentation and format in the marking is the challenging part of marking UID labels.

There are certain aspects of UID label making.

UID Labels Marking Requirements

The Department of Defense has mandated that the UID marking of the items should be in accordance with the criteria mentioned in the MIL-STD-130. The standard has mentioned that the contractors who are in charge of the items should mark them so as to meet the UID marking requirements.

The Data Required for UID Labels

The Government states the data that are essential for marking of the items with UID labels. The data include item number, part number, marking method, agency code, etc. Actually, the data elements require to construct the UID are the Unique identification of the item. As the data elements are entered in the 2D data matrix barcode format, it also requires a barcode scanner to decode the complete UID from the marking.

The UID data elements vary according to the construct of the Labels. The actual UID for Construct #1 consists of data such as Issuing Agency Code, Enterprise ID & Serial Number and for construct #2 it is Issuing Agency Code, Enterprise ID, and Part Number & Serial Number. On the other hand, the UID mark on the item consists of elements such as Enterprise ID & Serial Number with Data Qualifiers for Construct #1 and Enterprise ID, Part Number & Serial Number with Data Qualifiers for Construct #2.

The UID Label Construction

The marking of the UID labels should be according to particular format – construct #1 or construct #2. The UID standard requires that the data entered to the item s for the marking should be either of this formats for the barcode readers, scanner or verifier use the software that follows strict rules of UID constructions. If the data elements of the UID are not in the recommended format, it may be possible that the devices will not be able to decode the 2D data matrix barcode.

UID Labels Quality Assurance

As the UID labels are significant aspect of UID marking of the item and play a key role in the item management process, the quality of the labels are crucial feature of consideration. It is the responsibility of the contractors to investigate the manufacturing process of the vendors and present a Certificate of Conformance stating that the UID labels, nameplates or tags are manufactured keeping with the MIL-STD-130 standard. However, the marking process of the contractors is reviewed to ensure that there is no damage in the labels and the marking process is also not altered.

MIL-STD-130 Spec for UID Marking of the...

UID marking is crucial in any business practice and the MIL-STD-130 spec has stated the criteria for UID marking for easier item management.

The MIL-STD-130 spec has stated certain criteria for UID marking of the items. The unique identification marking for the items is a procedure of Department of Defense to simplify the item tracking process. According to the MIL-STD-130 spec the qualifying items for having unique identification include items with acquisition cost over $5000, mission essential, controlled inventory or serially managed items, and component of delivered items. DoD requires that the items must be permanently marked with 2D data matrix barcode. The data elements of the unique identification are item number, part number, serial number, CAGE code, etc. As the UII of the items are crucial for the item tracking process, the DoD requires that the marking should b permanent for the functional life time of the item.

There are certain aspects of UID marking that are essential to follow to get UID compliance of the marking.

Durable Material for the UID Label-

Basically, UID labels are preferred when the environment of the item or part is not suitable for direct part marking. In such case, durability of the labels or nameplates comes under the quality checking of the item UID. Hence, it is required that the contractors must choose the right material for the manufacture of the labels. MIL-STD-130 spec requires that the material of the labels shouldn’t cause any harm to the material or functionality of the item. Also it is required that the material of the labels must able to resist adverse conditions such as water, excess temperature, chemical processing, sunlight and other elements. Of course, choosing the right material for the nameplates or labels and the proper marking technique make all difference to the performance of the item. In case of the Direct Part Marking, the marking techniques of the part and item should be chosen carefully to give a permanent marking solution for the item.

UID Compliance of the Data-

The MIL-STD-130 spec has provided clear instructions for the data elements that must for the UID construction. The data elements are entered in the 2D data matrix code and are decoded with the help of a barcode scanner or reader. The data elements are item number, part number, manufacturer’s code, serial number, CAGE code, construct type, etc. The marking procedure of the data must provide permanent marking solution for the item. The marking should comply with the UID standard of MIL-STD-130 spec otherwise the software of the barcode scanner will not be able to identify the codes. Accuracy of the data is another element that proves it to be UID Compliant.

UID Data Verification-

The UID data of all the items should be submitted to UID Registry for their approval. UID Registry is the store house of UID data of the items and accepts or rejects the documents submitted by the contractors by verifying the accuracy and UID compliance. Hence, before submitting the data, the suppliers must confirm that the construction and marking of the UID data are according to the MIL-STD-130 spec.

The MIL-STD-130 spec mentions the criteria of UID marking and hence, it should be followed by the suppliers while marking the items to make them comply with the UID standard.

Marking Rules of IUID Labels for Propert...

The IUID labels are the effective IUID marking solutions for the DoD items and the marking method of the labels should be strategic and comply with the DoD requirements.

Use of IUID labels has become one of the methods of marking the parts with unique identification. Department of Defense (DoD) requires that all the DoD property including the property under possession of the contractors should be marked with IUID. The DoD has also mandated certain rules of marking the IUID labels that are applied to the parts. The process allows them keeping track of the item easily and also maintains a balance in the marking procedure of the different items. Hence, the contractors are required to stick to the marking rules of the IUID labels.

While using the IUID labels for marking items that are under the possession of the contractors, the prime consideration is that the contractors should take care of the data that are required for marking of the labels. There are certain other aspects of marking IUID labels.

As the government assigns each item with unique IUID, the contractors are required to use the same IUID while marking the IUID labels for the parts and also for reporting purpose.
In case, the contractors don’t have the previously established IUID for the parts, the contractors can establish an IUID to mark the IUID labels and submit the details of marking to the UID Registry.
The IUID labels are marked with concatenated IUID in the Construction #1 or construction #2 formats. Or else, they are marked with DoD recognized IUID equivalent.
While assigning IUID to incoming government furnished property, the serial number of the item may be replaced by the asset identification number.
While marking the IUID of the parts the contractors need to use the unique property control number and serial number along with the enterprise identifier.
In case of signing the repair contract with the contractors, the government mentions that the items are required to be marked with IUID before that particular item is delivered to the government after repair.
In case the property is not physically marked with the IUID even after being assigned with a unique identification, the contractor has to mark the parts with virtual IUID labels. When required the virtual IUID marking becomes permanent for the item.
The DoD requirements for marking of the items mentions that the IUID information that is etched on the IUID labels should comply with MIL-STD 130.
The contractors are required to maintain honesty and take responsibility in case the IUID labels of the property requires replacement due to damage, or lose. The new labels and nameplates should contain the same data of the IUID of the previous one.
If the contractor delivers the item in bulk and uses a single IUID labels for identification of a bunch of items, the contractor should conform the DoD before the delivery of the item about the specific procedure of item traceability.
It is the responsibility of the main contractor to ensure that the property under possession of the subcontractors is recorded under DoD UID Registry.

The marking guidelines enhance effective marking methods of the IUID labels.
