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.

The following spec refers to ASTM A380 for passivation of stainless steel and thus allows the use of ASTM A967: MIL-DTL-14072D/E/F (Table IV. Finish E300) The spec MIL-T-704K in section 3.2.6 directly describes a passivation process analogous to QQ-P-35's type II followed by a chromate post-treatment. However, QQ-P-35 assigns this process as ...

Both AMS 2700 and ASTM A967 base their nitric acid passivation methods on using 42° Baume nitric acid. The Baume scale is a measurement of specific gravity. Positive degrees of Baume indicate chemicals or solutions denser than water. 42° Baume nitric acid corresponds to a 1.4 specific gravity solution of nitric acid that is roughly 67% …

The ASTM A967 passivation standard applies to the cleaning, passivation and testing of stainless steel parts. Per passivation standard, ASTM A967 requires the parts to be immediately neutralized post immersion followed by a chemical treatment to treat the surface of the part. ASTM approved tests may include:
