This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
astk Appendix X1 gives some nonmandatory information and provides some general guidelines regarding the selection of passivation treatment appropriate to particular grades of stainless steel. This cycle shall be repeated a minimum of twelve times. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Determination of the suitability of this speci?
The cleaning of these contaminants from the stainless steel surface will facilitate the spontaneous passivation by allowing the oxygen uniform access to the aa967.
Immersion bath to be controlled at a pH of 1.
ASTM A – 05 Standard Specification for Chemical Passivation Treatments for Stainless Steel Parts
It includes several alternative tests, with acceptance criteria, for confirmation of atm of such treatments for stainless steel parts. At the end of this period, the surface shall be carefully rinsed and dried with care taken not to disturb copper deposits if present.
Last previous edition approved in as A — 01e1. Attention shall be given to maintaining adequate volume, concentration, purity, and temperature control appropriate to the size and amount of stainless steel to be treated.
Chemical passivation removes free iron and other surface contaminants from stainless steel parts, improving corrosion resistance. Your a697 will receive careful consideration at a meeting of the a9677 technical committee, which you may attend. The cloth pad used shall be used for only one such test, being changed for each test so as to avoid risk of contamination. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
All samples must pass the speci? Originally approved in These ASTM-approved tests may include: Precision and Bias Rejection and Retest 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.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee z967 Standards, at the address shown below.
A superscript epsilon e indicates an editorial change since the last revision or reapproval.
The formation of a dark blue color within 30 s denotes the presence of metallic iron. This test is not recommended for detection of free iron on ferritic or martensitic series stainless steels, because these steels will give a positive indication irrespective of the presence or qstm of anodic surface contaminants.
It makes no recommendations regarding the suitability of any grade, treatment, or acceptance criteria for any particular application or class of applications. NOTE 1—The selection of medium and procedures for a neutralization depends of the chemistry of the passivation and on economic considerations.
Practice F—Free Iron Test Practice A—Water Immersion Test Stainless steel passivation performed to the ASTM A standards meets these standards by passing tests that confirm its effectiveness, particularly as it pertains to removing free iron from the cold-worked surfaces.
