MIL-STD-867C, DEPARTMENT OF DEFENSE STANDARD PRACTICE: TEMPER ETCH INSPECTION (25 NOV 2008)., This standard establishes requirements and test for performingtemper etch inspection of carburized steels and tool and low alloy steels, which are heattreated above 1.24 x 109 Pascal (PA) (1.26 x 102 kilogram ?force/square millimeter(Kgf/mm2) or 1.8 x 105 pound ?force/square inch (psi). This standard applies to aircraftand missiles structural and propulsion system components when MIL-HDBK-6870 (forguidance only) and/or MIL-STD-866 are reference documents in the solicitation orcontract.
