Design Control Reference.

Reference Number Category Code (DRN_2910)


Non-Definitive U.S. Government Specification or Standard Reference. Any Government specification or standard reference other than those indicated in code 2 as definitive references.

5 - Replaced / Discontinued

Reference Number Category Code (DRN_2910)


Secondary Reference. Any additional number, other than a primary number (codes 1,2,3,4) informative reference (code 6) or vendor item drawing reference (code 7) assigned to an item of production or supply by a commercial or Government organization, which represents the same item of production or supply to which the National Stock Number (NSN) was assigned.
