ICS Code (Metallic coatings): 25.220.40
significance And Use:

This practice is applicable to chromate coatings of the colorless (both one and two-dip), iridescent yellow or bronze, olive drab, black, colorless anodic, yellow or black anodic types, and of the... View More

scope:

1.1 This practice covers a procedure for evaluating the protective value of chemical and electrochemical conversion coatings produced by chromate treatments of zinc and cadmium surfaces.

1.2 The protective value of a chromate coating is usually determined by salt-spray test and by determining whether or not the coating possesses adequate abrasion resistance.

1.3 Other methods, such as exposure to a humidity environment, can be used, but are generally of too long a duration to be of practical value. "Steam Tests" using pressure cookers have also been used for testing chromate films on hot-dip galvanized surfaces.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
