适用范围

The oil absorption value obtained by this test method gives information about the vehicle demand of the pigment when it is used in a pigment paste. Oil absorption values can be used to characterize pigments or batches of a given pigment.

This test method differs from Test Method D 1483 in that D 1483 involves only a gentle stirring and folding of the pigment, whereas this test method requires a thorough rubbing action. Because the end points are different, the values obtained from the two test methods generally differ.

1.1 This test method covers the determination of the oil absorption of pigments by the spatula rub-out technique.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.
