IUID standards have common purpose

NATO’s ability to bring together the military forces of its 28 member countries to achieve a common goal is extremely powerful. There are, of course, a number of challenges when it comes to joining many disparate organizations to work together. One area where this becomes apparent is in the sharing of defense equipment. It can be difficult for just one defense department to keep track of all its assets, which may have lifetimes of decades and are spread among worldwide operations. Loaning the equipment to other organizations adds an additional layer of complexity.

Defense departments are turning to unique identification of items (IUID) to help solve the problem of tracking assets. Equipment that has a certain value and/or is considered mission critical receives an identifier that is globally unique and remains with the item for its entire life. Governments have developed standards that apply to all aspects of IUID labeling. In the U.S., the standard is MIL-STD-130; the U.K. has DEF STAN 05-132.

NATO has issued its own standards to bring even more consistency to IUID systems. The organization has released the Allied Unique Identification of Items Publication, or AUIDP-1, and an associated document, STANAG 2290. Individual defense departments refer to the NATO standards when developing their own IUID standards.

Topics covered by IUID standards such as MIL-STD-130, DEF STAN 05-132 and STANAG 2290 include what information to include in an item’s unique identifier and how the information should be formatted. The identifier is encoded in a 2D Data Matrix symbol that is either applied directly to the item or attached via a label or plate. The symbol is read using an IUID scanner. It’s crucial that departments use the same identifier format so the information can be read and interpreted by all users.

The standards address the appropriate size of the Data Matrix symbol and where it should be placed on the item it is identifying. There are also methods spelled out for verification of the data matrix symbol, to ensure it is readable.

The similar, but not identical standards for IUID labeling, along with the complexity of each, can be confusing for a contractor supplying equipment to a defense department. Consulting with a company that is an expert in this field may help. For example, ID-Integration Inc. has more than 12 years of experience in IUID systems and is well-versed in the various standards including DEF STAN 05-132 and STANAG 2290.  For more information, visit www.id-integration.com.

Attention to detail needed when implementing UID systems

Marking defense assets with unique identifiers that can be used to track the items throughout their lifetime is a straightforward concept. But when it comes to implementing Unique Identification of Items according to NATO standards, one must pay attention to numerous details. Many of these specifics can be found in two documents: AUIDP-1 (Allied Unique Identification of Items Publication) and a Standardization Agreement, STANAG 2290. 

Benefits of UID

Unique Identification of Items (UID) is a standardized method for giving items a unique identifier that stays with them throughout their life. It’s useful for tracking ownership and location of an asset, which may be in use, in storage or in transit. AUIDP-1 also notes that UID can provide details of an asset’s age, condition, configuration, maintenance and repair history, and warranty status.

UID utilizes the 2D Data Matrix symbol for labeling items. The label is read with an automated device and provides a common format for storing and retrieving information among many different users. Errors are reduced as compared to manual data entry and the process is streamlined.

When to use UID

Implementing UID makes the most sense for items that are newly purchased. In that case, the benefits of UID will be realized throughout the item’s entire life for a greater return on investment. Items that are already in inventory might also be good UID candidates if their remaining life is substantial. Other factors to weigh include whether the item has significant value; is repairable; requires calibration or confirmation of disposal; or is mission critical.

Preferred UID methods

The Unique Item Identifier, or UII, assigned to an item must not change over the item’s life, even if other identifiers such as the part number change. It must be globally unique and cannot be reused, even if the item it’s attached to is disposed of.

Data associated with the UII is entered into a registry. Annex 6 of AUIDP-1 lists the recommended data elements to include. Some of these are: Unique Item Identifier; type of item (either end item or embedded item); whether it’s marked using UID Construct 1 or Construct 2; part number; serial number; batch or lot; description; and issuing agency code.

Methods for marking items include direct marking using laser, electro-chemical etching or dot peen indenting. STANAG 2290 contains standards for minimum cell sizes and quality levels for the various methods. The label should last for the expected life of the item, STANAG 2290 notes.
