ASTM D2988-96(2010)

These test methods are used to establish manufacturing and purchasing specifications. These test methods will provide a means of determining the condition of the solvent in use. A high water soluble chloride level may indicate the start of solvent decomposition.

1.1 Test Methods 1, 2, and 3—These test methods cover the determination of water-extractable halide ion in halogenated organic solvents and their admixtures. Fluoride ion is not measured due to the solubility of silver fluoride.

1.2 Test Method 4—This test method covers the determination of chloride ion in halogenated organic solvents and their admixtures.

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

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. Specific precautionary statements are given in Section 6.
