ANSI_ABMA B3-3-1992
This specification for temper etch inspection details the methods and controls for performing etching of ground surfaces for the detection, qualification, and control of altered metallurgical structures of various metallic alloys subjected to grinding. This specification presents two basic methods of etch, one of alcohol base and another of water base, in addition to use of a photo­graphic gray scale to control bath immersion times and part etching levels. This standard parallels MIL-STD-867 A (USAF), Military standard temper etch inspection.
