1.1 This test method covers the determination of the miscibility of water-soluble solvents with water. While written specifically for testing acetone, isopropyl alcohol (isopropanol), and methyl alcohol (methanol), the method is suitable for testing most water-soluble solvents. 1.2 This test method serves to detect water-immiscible contaminants qualitatively; the level of detection of these impurities varies widely with both the type of solvent and the type of impurity. 1.3 The level of detection of water-insoluble materials depends upon the solvent tested and the type of impurity or impurities present, that is paraffin, olefin, aromatic, high molecular weight alcohol, or ketone, etc. There is, therefore, no specific level of impurity detected by this procedure. Note 1 -This test method is normally performed at ambient, but other temperatures may be used as specified by the consumer and supplier. 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. 1.5 For specific hazard information and guidance, consult the supplier's Material Safety Data Sheet for materials listed in this test method.
