ASTM D962-81(2020)

Standard Specification for Aluminum Powder and Paste Pigments for Paints

ABSTRACT
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.
SCOPE
1.1 This specification covers four types and three classes of aluminum pigments for use in paints.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
