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.

1. Passivation Process: ASTM A967 defines the passivation process as the removal of free iron or other foreign matter from the surface of stainless steel by means of a chemical treatment. This treatment encourages the formation of a passive oxide layer, strengthening the steel's resistance to corrosion. 2.

Passivation of Stainless Steel to ASTM A967. Five nitric and citric methods are listed as follows: Nitric 1: 20-25 v% Nitric Acid, 2.5 w% Sodium Dichromate, 120-130F, 20 Mins minimum. Nitric 2: 20-45 v% Nitric Acid, 70-90F, 30 Mins minimum. Nitric 3: 20-25 v% Nitric Acid, 120-140F, 20 Mins minimum.

AMS 2700 does not allow for a user-defined set of passivation parameters (A967 Nitric Methods 4 & 5, Citric Methods 4 & 5) even if they are proven to pass a verification test. This is AMS 2700's greatest procedural difference from ASTM A967. With AMS 2700's larger variety of qualified parameters, one of the sets must be followed.
