(Test Method)Standard Test Method for Water Miscibility of Water-Soluble Solvents
Standard Test Method for Water Miscibility of Water-Soluble Solvents
SIGNIFICANCE AND USE
Water-insoluble materials present in a solvent expected to be completely water miscible may interfere with many uses of the solvent. This test method provides a measure of the miscibility of water-soluble solvents with a polar medium-water. It also provides a qualitative indication of the presence or absence of water-immiscible contaminants.
The results of this test method may be used in assessing compliance with a specification. Prior to agreeing to this test method as the basis of a specification requirement, it may be desirable that the interpretation of what constitutes cloudiness or turbidity be agreed upon between the supplier and the purchaser.
SCOPE
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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 For specific hazard information and guidance, consult the supplier's Material Safety Data Sheet for materials listed in this test method.
1.6 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.
