ASTM A967 vs. AMS 2700? Which is the right passivation spec?

What requirement or standard is he auditing passivatiin against, since clearly it is not A? F86 refers to surgical implants of any metallic alloy, and basically just says “do whatever treatment is applicable and appropriate to ensure corrosion resistance”. It appears that the types are associated with method 1, not method 2. A has a lot of excellent recommendations on general cleaning etc.

AMS Method 1 Type II Passivation for Medical Device

The passivation process consists of immersing the stainless steel in a solution of citric acid, or other acid plus oxidizing salts, which dissolves the embedded or deposited iron and restores the original corrosion-resistant surface a thin, transparent oxide film. Can you please tell me the differences between the passivation processes AMS [link by ed. There are other in-house specifications for some companies.
