Significance and Use
4.1 The oil absorption value obtained by this test method provides information about the vehicle demand of the pigment when it is used in a pigment paste. Oil absorption values can be used to characterize batches of a given pigment.
4.2 This test method differs from Test Method D281 in that D281 requires a vigorous rubbing action whereas this test method involves only a gentle stirring and folding of the pigment. Because the end points are different, the values obtained from the two test methods generally differ.
Scope
1.1 This test method covers the determination of oil absorption of pigments by the Gardner-Coleman procedure.2
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 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.
