ASTM D962 - 81(2008)e1 Standard Specification for Aluminum Powder and Paste Pigments for Paints
Description of Standard
This specification covers aluminum pigments in powder and paste forms for use in paints. The aluminum pigments are available in four types, as follows: Type I, leafing powder; Type II, leafing paste; Type III, nonleafing powder; and Type IV, nonleafing paste. Each type is grouped into three classes based on residue retained on a No. 325 sieve, as follows: Class A, fine; Class B, medium; and Class C, coarse. Materials shall be sampled, tested, and conform accordingly to composition of non-volatile matter, easily extracted fatty and oily matter (polishing lubricant), total impurities other than fatty and oily matter, coarse particles as total residue retained, and leafing ability.
