scope:

This standard defines the "Brush-Off Blast Cleaning" end condition of uncoated or coated metal surfaces other than carbon steel that have been prepared using abrasive blast cleaning techniques. The standard also includes requirements for materials and procedures necessary to achieve and verify the end condition.

Substrates that may be prepared by this method include but are not limited to: galvanized surfaces, copper and copper alloys, aluminum and aluminum alloys, and stainless steel. Sections A2 through A4 of Appendix A include special considerations for three families of alloys. Personnel performing abrasive blasting should be able to identify the alloy family from material test reports, design information, or field testing.

This standard includes requirements for removal of visible surface contaminants. Information on nonvisible contamination is in nonmandatory Appendix A5.

This standard provides both IEEE/ASTM⁽¹⁾ SI 10 International System Units (SI) units and U.S. Customary units. SI Units are presented first, with a conversion into approximate U.S. custom units shown in parentheses. The conversions are not exact; therefore, each system must be used independently of the other.
