AMS 2700 has no guidelines for descaling or chemical cleaning processes detailed in ASTM A380 and ASTM A967; AMS 2700 is strictly a specification on passivation processes. ASTM A967 describes a passivation procedure must follow cleaning and / or descaling. Any contamination not removed prior to passivation reduces a part's corrosion ...

According to ASTM A967, passivation is the chemical treatment of stainless steel with an oxidant agent, to remove free iron or other materials. The passivation baths commonly use citric and nitric acid as oxidizing agents. However, the latter generates toxic vapors that are harmful to health [22,23,24]. On the other hand, citric acid is ...

One is a commercially available citric acid passivation solution that contains citric acid and cleaning compounds and meets ASTM A 967 (Citric 4), and the other two passivation solutions are Type II and Type VII from AMS-QQ-P-35. These AMS-QQ-P-35 solutions are used by the aerospace industry to passivate stainless steel parts.

Scope. 1.1 This test method covers a means of testing the surface insulation resistivity of single strips or punchings of flat-rolled electrical steel under predetermined conditions of voltage, pressure, and temperature. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

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.
