4.1 This test method is useful for the determination of the amount of acid acceptance contributed by amines or bases as compared to other acid-accepting compounds.

1.1 These test methods, where applicable, cover the determination of the acid acceptance of halogenated organic solvents due to the presence therein of an organic amine titratable by standard acid. These test methods are suitable for samples of 0.001 to 0.02 weight percent (10 – 200 ppm) alkalinity as NaOH. Two test methods are covered as follows:

1.1.1 Test Method A—pH Method, and

1.1.2 Test Method B—Indicator Method.

1.1.3 Test Method C—GC Method.

1.2 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.
