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 …
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 …
A. As Ken says, ASTM A380 [affil link] should not be used as a passivation specification, and QQ-P-35 has been canceled.

Scope. 1.1 This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a density in excess of 800 kg/m 3 [50 lb/ft 3 ]. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard.
ASTM A967 and ASTM A380 – two of the most widely recognized industry standards for passivation – list a number of methods that can be used to passivate a part; however, they do not claim to be all-encompassing. ASTM recognizes that there are many valid ways to passivate a stainless steel part.
