TEMPER ETCH INSPECTION
|Publication Date:||25 November 2008|
This standard establishes requirements and test for performing temper etch inspection of carburized steels and tool and low alloy steels, which are heat treated 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 aircraft and missiles structural and propulsion system components when MIL-HDBK-6870 (for guidance only) and/or MIL-STD-866 are reference documents in the solicitation or contract.
This standard provides the step by step process and procedures for temper etch to be used during repair process and acquisition of spares for the landing gear of all military aircraft.
