ASTM D869-85(2004)

Paints, if not formulated or processed properly may settle excessively. Paint that settles excessively is difficult to reincorporate into the paint system causing time delays or valuable pigment being left in the drum. This test method is an attempt to evaluate the degree of settling caused by the accelerated Test Method D 1309. This very subjective method of evaluation in conjunction with the variables of Test Method D 1309 raises questions as to the usefulness of the results for specification compliance.

1.1 This test method covers the determination of the degree of pigment suspension and ease of remixing a shelf-aged sample of paint to a homogeneous condition suitable for the intended use.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 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.
