MIL-STD-130N
d. When the PIN, lot or batch number changes, the new current PIN, lot or batch number shall be included on the item in accordance with the applicable MRI protocol requirements (see
5.2.2) using the applicable MRI protocol data qualifiers in Table VI. The new current PIN, lot or batch number may be encoded in a single Data Matrix symbol along with the UII data elements
at the discretion of the MRI protocol used. For UII Construct #2 applications, the original PIN, original lot number, or original batch number must continue to be clearly identified and encoded in the MRI. When the PIN, lot or batch number is changed by an enterprise other than the source enterprise (manufacturer or supplier) identified in the original mark, the EID of the enterprise establishing the changed PIN shall be clearly identified on the changed item as MRI or HRI per
5.2.1.1 (see Figure 7).
NOTE: Where instances of duplicate part number assignments arise within the enterprise, enterprises may choose to utilize item identification (see 3.31) by prefixing the part number with the original design activity identification, such that each part is distinctly identified within the enterprise.
5.2.1.4 DoD recognized IUID equivalent. Applicable DoD recognized IUID equivalents (see 3.33) shall be constructed in accordance with the specifications governing that equivalent. The IUID equivalent shall be encoded using the syntax of ISO/IEC 15434 and the applicable data qualifiers for the DOD recognized item IUID equivalent in Table VI.
NOTE: GS1 IUID equivalents may be encoded using Function Code 1 (FNC1) in lieu of the syntax of ISO/IEC 15434.
5.2.1.5 Assignment of IUID to legacy items. The IUID mark is supplemental to prior marks on the item and it only needs to replicate UII related information. When it is determined that a legacy item should be marked in accordance with the IUID marking requirements, the Enterprise Identifier (EID) of the organization ensuring the uniqueness must be the EID used to generate the UII versus any other EID represented in the prior marks. Although existing marks on an item may contain the necessary elements for a concatenated UII, they do not guarantee the resulting UII will be unique. Only the EID owner establishing the UII can provide such guarantee. Legacy marking guidance is provided in the DOD Guide to Uniquely Identifying Items.
5.2.2 Machine-readable information (MRI) marking protocol. Unless manufacturers follow one of the established standards stated herein, items shall be marked in accordance with MH10.8.7. Labeling activities shall follow one of the established standards stated herein or as noted in 5.2.2.6
5.2.2.1 Air Transport Association (ATA). Manufacturers that implement ATA product marking standards shall mark items in accordance with:
a. For linear bar code symbols: SPEC2000.
b. For Data Matrix symbols: ATA CSDD using data qualifiers (TEIs) shown in Table VI
and ISO/IEC 15434 syntax with format indicator "12".
5.2.2.2 Automotive Industry Action Group (AIAG). Manufacturers that implement the AIAG standards shall mark items in accordance with the AIAG B-4 and AIAG B-17 standards as applicable (see Figure 12).
5.2.2.3 Consumer Electronics Association (CEA). Manufacturers that implement the CEA standards shall mark items in accordance with the MH10.8.7 and CEA-706 standards as applicable. (see Figure 13) Although other manufacturer codes are allowable under this
