ASTM A380 Primarily a document about the cleaning of stainless steel, a section on nitric acid passivation was included. Though used by many as a specification for stainless steel passivation, A380 is now outdated on that subject. A967 should be referred to where a standard for stainless steel passivation is needed.What is ASTM A967 - Specification for Chemical Passivation astm a380 vs a967ASTM A967 Chemical Passivation Treatment for Stainless Steel.

A967 should be referred to where a standard for stainless steel passivation is needed. However, as introduced in the 2013 revision of A380, it does also directly allow the use of passivation methods from A967, including citric acid (see section 6.4). A380 is available from the ASTM website.
