ASTM D480-88(2003)

Standard Test Methods for Sampling and Testing of Flaked Aluminum Powders and Pastes

SIGNIFICANCE AND USE
Flaked aluminum pigments are produced in a variety of forms. These test methods allow the user to determine the applicability of a given product to this use.
SCOPE
1.1 These test methods cover procedures for sampling, qualitative analysis, and physical testing of flaked aluminum powders and pastes (leafing and nonleafing) for coatings.
1.2 These test methods apply equally to leafing and nonleafing flaked aluminum powders and pastes except where noted to the contrary.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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. For a specific hazard statement, see 7.3.1.
