3.1 Water in a solvent may interfere with many uses of the solvent. This test method provides a measure of the miscibility of lacquer solvents with a nonpolar medium-heptane. It also provides a qualitative indication of the presence or absence of moisture in these solvents (often esters and ketones). The results of these measurements may be used for specification acceptance.

1.1 This test method covers determination of the miscibility of lacquer solvents with heptane. It may also be used to detect qualitatively the presence of moisture in esters and ketones.

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

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.
