MIL-STD-1285-SUP-2 Marking of Electrical and Electronic PartsThis standard establishes requirements for the physical marking of electrical and electronic parts. This standard should be implemented by incorporating suitable requirements directly in acquisition documents.

4.5.4 Marking of altered or selected items (see ASME Y14.100). Items which are altered or selected from the controlling specification or standard shall be identified by CAGE code and a part number established by the using design activity drawing which depicts requirements for such alterations or selection.

4.5.5 Marking of source control items (see MIL -STD -130). When marking of source control items, they shall be marked with the design activity's CAGE or NSCM code, the source control notation (SOCN), and the source control part number; (such as, 12345SOCN80678932). The vendor's CAGE code and identifying number need not be removed.

4.5.6 Marking of vendor items (see MIL -STD -130). When marking vendor items, they shall be marked with the manufacturer's (vendor's) PIN preceded by the manufacturer's CAGE or NSCM code. The vendor drawing number shall not be used to physically reidentify the item from the original design activity's PIN, in the event that a vendor item is a commercial off the shelf (COTS) item, as specified in 4.5.7.

4.5.7 Marking of commercial off the shelf (COTS) items (see MIL -STD -130). COTS items marked with commercial identification and which present no identification difficulty may be exempt from additional marking requirements unless otherwise specified by contract or order. This exemption extends to vendor items identified as COTS.

4.5.8 Marking of reidentified items (see ASME Y14.100). When items are identified by more than 15 characters (not including the CAGE or NSCM code), or do not meet the other requirements of ASME Y14.100 and a design activity has no control over this assignment, it may assign a design activity control number to the item to meet the identification requirements of that standard (NOTE: DoD specifications that are authorized to exceed the 15 digit limitations are exempt from this requirement).

4.5.9 Method I (typographical marking). The applicable markings of table I shall be individually marked on the part or unit package where necessary. Letters shall be without serifs (sans-serifs) such as Gothic of Futura capitals, and the numeral shall be Arabic except when Roman numerals are used for type designation in DoD specifications and standards. Characters generated by automation techniques (such as interactive graphic systems or stencil) are permitted. Numbers, symbols, trademarks, and other like markings shall be similar in appearance and size to the lettering. When marking processes include the use of marking materials such as inks or paints, these materials shall contrast with the body color of the part to insure legibility. The acquisition

document shall specify the sequence and division of line spacing of marking based on the order of precedence specified in table I. However, the sequence may deviate from the order of precedence to accommodate the part configuration and peculiarities of identification marking.
