NOTE 1—The selection of medium and procedures for a neutralization depends of the chemistry of the passivation and on economic considerations. Not all of the following tests are suitable for all grades of stainless steel. Determination of the suitability of this speci?
ASTM A – 05 Standard Specification for Chemical Passivation Treatments for Stainless Steel Parts
A number in parentheses indicates the year of last reapproval. It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts. It includes several alternative tests, with acceptance criteria, for confirmation of a697 of such treatments for stainless steel parts. Current edition approved Sept.

The cloth shall be in contact with the steel a9677 an area of at least 20 square inches cm2. Practice C—Salt Spray Test The SI units w967 in parentheses are for information only. The ASTM provides instructions and acceptance criteria for these and other tests that can verify the quality of a stainless steel passivation operation. This standard does not purport to address all of the safety concerns, if any, associated with its use.
Such treatments may include externally applying an electrical potential on the stainless steel parts, as in the case of electropolishing.
ASTM A967 Passivation Standard
The SI units given in parentheses are for information only. ASTM International takes no position respecting the validity of any patent rights asserted 50 connection with any item mentioned in this standard. Such records shall be available for inspection when speci? A rejected lot may, at the option of the processor, be re-passivated, with or without re-pretreatment, and then be retested.
By meeting standards set by the ASTM and other organizations, we can ensure consistently-high quality for a broad range of metal parts across many industries. Lot, Frequency of Testing, and Selection of Test asrm The cloth pad used shall be used for only one such test, being changed for each test so as to avoid risk of contamination. At the end 055 this period, the surface shall be carefully zstm and dried with care taken not to disturb copper deposits if present.
The cleaning of these contaminants from the stainless steel surface will facilitate the spontaneous passivation by allowing the oxygen uniform access to the surface. The test solution shall be mixed fresh on the day of the test. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

This standard does not purport to address all of the safety concerns, if any, associated with its use. After removal of the cloth pad, the surface of the part shall be allowed to dry in air before inspection. These tests include the following practices: Immersion bath to asmt controlled at a pH of 1.
The surface of stainless steel that has been pickled is free of scale, free iron, and exogenous foreign ashm, and does not require a separate treatment for passivation as de?
Appendix X1 gives some nonmandatory information and provides some general guidelines regarding the selection of passivation treatment appropriate to particular grades of stainless steel.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. These ASTM-approved tests may include: It is especially useful for large parts that have been uniformly cleaned but that are inconvenient for reasons of size of equipment or ease of handling satm the part to place in the environments de?
