ASTM D2989-01(2016)

Standard Test Method for Acidity-Alkalinity of Halogenated Organic Solvents and<brk /> Their Admixtures

SIGNIFICANCE AND USE
4.1 This test method can be used to establish manufacturing and purchasing specifications. It can also be used to determine the condition of solvents in use.
SCOPE
1.1 This test method covers the determination of acidity in halogenated organic solvents and admixtures thereof. The alkalinity may be determined utilizing Test Methods D2106, by substituting the end point measured at pH 7 by bromothymol blue or pH meter.  
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. Specific precautionary statements are given in Section 7.

3. Summary of Test Method
3.1 A sample of halogenated solvent or admixture is measured for pH using Test Method D2110. If the pH of the sample is
above 7.0, the alkalinity is determined using Test MethodMethods D2106 (to an end point of pH 7). If the pH is below 7.0, the
free acid content of the halogenated organic solvent or admixture is determined after water extraction using Procedure A, or can
be determined directly using Procedure B.
