ASTM-B137 › Standard Test Method for Measurement of Coating Mass Per Unit Area on Anodically Coated Aluminum
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This test method covers determination of the mass per unit area of coating on anodically coated aluminum and its alloys.
1.2 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.
Significance and Use
3.1 This test method is a destructive test procedure suitable for quality control within manufacturing operations for coating mass on anodically coated aluminum and aluminum alloys. The mass of the coating is an approximation of its thickness provided the conditions under which the coating was applied, or the density of the coating, are known. An anodic coating's protective value and amenability to coloring by dying or electrolytic methods are related to mass of coating per unit area.
