What is ASTM A967 Passivation? 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:

ASTM A967/A967M-17 (CITRIC ACID) 7.1.1.1 Citric 1—The solution shall contain 4 to 10 weight percent of citric acid. The parts shall be immersed for a minimum of 4 min at a temperature in the range from 60 to 70°C [140 to 160°F] 7.1.1.2 Citric 2—The solution shall contain 4 to 10 weight percent of citric acid.

The ASTM A967 passivation standard applies to the cleaning, passivation and testing of stainless steel parts. Chemical passivation removes free iron and other surface contaminants from stainless steel parts, improving corrosion resistance. Stainless steel passivation performed to the ASTM A967 standards meets these standards by passing …

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.
