MIL-PRF-31032A (w/AMENDMENT 1), PERFORMANCE SPECIFICATION, PRINTED CIRCUIT BOARD/PRINTED WIRING BOARD, GENERAL SPECIFICATION FOR (24 FEB 2006)., This specification establishes the general performance requirements for printed circuit boards or printed wiring boards (hereafter designated printed board) and the verification requirements for insuring that these items meet the applicable performance requirements. Certification and qualification to this specification allows manufacturer's to apply the Qualified Manufacturers List (QML) program to printed boards procured to non-QML documents such as MIL-PRF-55110 and MIL-P-50884 (see 6.3.4 and 6.5). The intent of this specification is to allow the printed board manufacturer the flexibility to implement best commercial practices to the maximum extent possible while still providing product that meets military performance needs (see 6.3.3).
