MIL-STD-130 Identification Marking Of U.S. Military PropertyThis standard provides the item marking criteria for development of specific marking requirements and methods for identification of items of military property produced, stocked, stored, and issued by or for the Department of Defense DoD. This standard addresses criteria and data content for both free text and machine-readable information MRI applications for identification marking of U.S. military property.

w/Change 1

subject to IUID marking, the preferred MRI is a Data Matrix symbol with HRI (translation or interpretation). When a Data Matrix symbol is used, linear symbols may be omitted unless specifically required by the marking protocol, contract, or order. The Data Matrix symbol shall meet the requirements stated in 5.2.3.2 and 5.2.7.2. Items shall be individually marked as follows:

a. MRI with HRI (translation or interpretation) may be used in lieu of the item identification free text (see 5.3).

b. Deleted. c. Deleted.

d. Where space is limited, the module size of the data matrix can be reduced to 0.001 inch

(0.025 mm) allowing marking of small items such as electronic components.

5.2.1 Minimum information content. MRI content requirements not included in the MRI marking protocols of 5.2.2 shall be specified in the contract or order. For the following sub- paragraphs, if the enterprise chooses to encode the UII data set as a single element (see Table

VI), marking of UII component data set elements (e.g. EID that assigned the serial number, serial number, original PIN, lot, or batch) is optional unless marking of the component elements is specified by the marking protocol or contract. The optional marking provision for UII

component data set elements does not affect the marking requirement for the source (manufacturer or supplier) and PIN. The minimum MRI content requirements are conditional as follows:

5.2.1.1 Applicable enterprise identifier (EID) (see 3.2).

a. Each item's MRI marking shall include the EID of the item's source (manufacturer or supplier) (see 3.2 (Source)) encoded using Table VI data qualifiers in accordance with an MRI marking protocol (see 5.2.2), if encoding the source EID does not cause UII ambiguity issues (also see 5.2.1.5 for legacy item exception). When the item's source (manufacturer or supplier) EID is not marked as MRI with accompanying HRI (translation or interpretation), the source EID shall be marked as free text using Table VIII titles (see Figure 7, Construct #2).

b. For IUID marks, the EID for the activity assigning the serial number for UII Constructs

#1 or #2 shall be encoded using MRI protocol data qualifiers in Table VI, except that if a UII data set is encoded as a single element on the item, the EID of the activity assigning the serial number need only be encoded as a discrete element if specified by the marking protocol or contract. The EID of the activity assigning the serial number may be the same as or in addition to the EID of the item's source (manufacturer or supplier); if the same, only one EID entry is required. If multiple EID data qualifiers are used in the same symbol to encode the data elements, the UII data set shall be encoded with a single element data qualifier (i.e. 18S, 25S, UID, UST, USN, or DoD-recognized IUID equivalent) so the UII may be derived regardless of any apparent ambiguity introduced by multiple EID data elements in the symbol. See Appendix A for the applicable business rules to determine if ambiguity exists when deriving a UII from a UII data set.
