ASTM A967. General industries use this standard to describe and control the passivation of stainless steel. Passivation is a process of making stainless steel more stainless than it would be if left alone. It is based on using an acid (nitric or citric) under highly controlled conditions to remove free iron particles from the surface and to help form a metal oxide …

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.
For example, ASTM A967 contains more options for passivation verification tests while AMS2700 provides more guidance on sampling large batches of components for testing and inspection after passivation. As the most direct linear descendant of QQ-P-35, AMS 2700 naturally shows its "heritage". QQ-P-35 types II, VI, VII and VIII are equivalent ...
