NOTE 2—Some of the tests may produce positive indications not associated with the presence of free iron on the stainless steel surface. The test solution shall be mixed fresh on the day of the test. It includes several alternative tests, with acceptance criteria, for confirmation of effectiveness of such treatments for stainless steel parts. A number in parentheses indicates the year of last reapproval.
A rejected lot may, at the zstm of the processor, be re-passivated, with or without re-pretreatment, and then be retested. Precision Machining Technology Show.

These particles must be removed or they will appear as rust or stain spots. Minor changes have been made in the text to facilitate references to the main document and to correct technical inaccuracies.
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. The cloth shall be in contact with the steel for an area of at least 20 square inches cm2.
Stainless Steel Passivation and More Able Electropolishing provides metal passivation services that meet the ASTM A standards, as well as other finishing treatments that improve the corrosion resistance of stainless steel and various other alloys. 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 absence of anodic surface contaminants.
The effectiveness of any passivation treatment is demonstrated by the parts meeting the speci? It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts. Such treatments may include externally applying an electrical potential on the stainless steel parts, as in the case of electropolishing. Active view current version of standard. Lot, Frequency of Testing, and Selection of Test Originally approved in At the end of this period, the surface shall be carefully rinsed and dried with care taken not to disturb copper deposits if present.
