1.1This 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.

1.2This 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.

1.3The 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.

1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5For specific hazard information and guidance, consult the supplier’s Safety Data Sheet for materials listed in this test method.

1.6This 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.

1.7This 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.
