ASTM A967/A967M 2013 Edition has just been released and is available from Document Center Inc. in either paper or pdf format. Titled “Standard Specification for Chemical Passivation Treatments for Stainless Steel Parts,” the new revision is one of our go-to documents for chemical passivation. It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts.
Included are the following tests:
- Practice A—Water Immersion Test,
- Practice B—High Humidity Test,
- Practice C—Salt Spray Test,
- Practice D—Copper Sulfate Test,
- Practice E—Potassium Ferricyanide–Nitric Acid Test, and
- Practice F—Damp Cloth Test.
This practice references QQ-P-35 (later renumbered AMS-QQ-P-35 and then withdrawn in favor of AMS-2700), another major passivation document. The ASTM A967/A967-13 replaces ASTM A967/A967M-05 which is now obsolete.
Changes to the new 2013 Edition of A967/A967M can be found in the following areas: Section 1.5 (changed to combined Metric/US units), Revised Section 4.1 and added Section 4.3, Added Notes 2 and 3 to Sections 6 and 7, Revised Section 13.3, Combined Sections 14 through 19 into a new Section 14, Revised Section 22.1 (Now numbered 17.1) and added Section 17.2, and Added Sections X1.3.2-X1.3.4 and X1.12 to the Appendix.
