Further information is necessary for Construct 1 and Construct #2, as described in MIL-STD-130. Regardless of how the item is marked, it must meet the requirements of MIL-STD-130 with regards to the information contained therein and the arrangement of the information. Examples of other standards include those of the Air Transport Association (ATA), Consumer Electronics Association (CEA), and National Aeronautics and Space Administration (NASA).In order to gain improvements in asset management, the Department of Defense requires all tangible assets to be tagged according to specific requirements, which are summarized in MIL-STD-130. Suppliers to the Department of Defense must follow these references, but should be aware that the MIL-STD-130 always takes precedence over any other document when there is a conflict between the two. These are detailed in the standard, and include items that already have a unique identifier (such as a vehicle identification number), items that are covered by other standards or are in some other way exempt. This system allows the military to improve the efficiency and accuracy of their asset # management system, much as civilian businesses have achieved in recent years.Machine-readable information (MRI) is preferred by MIL-STD-130, and generally follows ISO standards for linear bar codes and data matrix symbols although other standards may apply.MIL-STD-130 describes the details of the tagging requirements, and references numerous other industry and government documents.MIL-STD-130 is a complicated specification and it must be followed rigorously. Guidelines for human-readable information are also given in MIL-STD-130, including font and numeral type and size. For this reason, the reader is advised to consult with the experts at ID-Integration to ensure complete compliance with the standard. The information inscribed on the tag or label must include the Enterprise Identifier (EID) of the supplier or manufacturer, the Part or Identifying Number (PIN), and the lot or batch number of the item..For items that are required to be tagged, the identification markings must be on a plastic or metal plate, band, tag or label that is firmly and permanently attached to the item. The arrangement of information depends on if the manufacturer is the Original Design Activity (ODA) or not and also must cover maintenance actions.The supplier must also be aware that there are numerous items that are excluded from the requirements of MIL-STD-130. MIL-STD-130 also allows the markings to be directly applied to the item, for example, by laser scribing. Extensive details are given in the standard.
