Scope

1.1 This test method covers the procedure for the quantitative separation of the vehicle from the pigment in solvent-reducible coatings.

1.2 This test method has been proven to be applicable to the following types of paints: white linseed oil outside house paint, white soya and phthalic alkyd enamel, white linseed o-phthalic alkyd enamel, red lead primer, zinc chromate primer, flat white inside enamel, white epoxy enamel, white vinyl toluene modified alkyd, and white amino modified baking enamel. It is considered to be applicable to most solvent-reducible paints.

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. Specific hazard statements are given in Section 6.

Significance and Use

This test method is suitable for setting specifications for the pigment content of solvent-reducible paints as well as for monitoring manufacturing quality control.

This test method provides the isolated pigment fraction from solvent-reducible paints that may be used for pigment analysis.
