A 967 2 3. Terminology 3.1 Definition of Term Specific to This Standard—It is necessary to define which of the several commonly used definitions of the term passivation will be used in this specification.(See Discussion.) 3.1.1 Discussion—Stainless steels are autopassivating in the sense that the protective passive film is formed spontaneously
Ultimately, AMS2700 and ASTM A967 are excellent successors to the foundation set by QQ-P-35. Adding citric acid to these modern standards reduces the possible hazards to the people performing the passivation work and easing the disposal considerations of chemicals used.

ASTM A967 defines seven tests for verification that a suitable passive surface has been formed on the component surface. These tests are all qualitative. Although some tests can more precisely detect the amount of free iron remaining on a surface, they are meant to serve as a go, no-go test for passivation. Water immersion test.
