(Test Method)Standard Test Methods for Nonvolatile Matter in Halogenated Organic Solvents and Their Admixtures
Standard Test Methods for Nonvolatile Matter in Halogenated Organic Solvents and Their Admixtures
SCOPE
1.1 These test methods cover the determination of nonvolatile matter in halogenated organic solvents and admixtures.
1.2 Five test methods are covered, as follows:
1.2.1 Test Method A—For halogenated organic solvents or admixtures having less than 50 ppm nonvolatile matter; or where precision greater than ±10 ppm is required.
1.2.2 Test Method B—For halogenated organic solvents or admixtures having more than 50 ppm nonvolatile matter or where precision of ±0.001 % (10 ppm) is satisfactory.
1.2.3 Test Method C—For low-boiling halogenated organic solvents or their admixtures (for example, methylene chloride, trichlorotrifluoroethane) that may superheat and cause bumping while evaporating to dryness with steam. A precision of greater than ± 10 ppm can be attained.
1.2.4 Test Method D—For rapid measurement of nonvolatile matter in halogenated organic solvents and their admistures and where precision better then ±10 ppm is required.
1.2.5 Test Method E—For halogenated organic solvents or admixtures and where precision better than ±10 ppm is required.
1.3 The values stated in SI units are to be regarded as the 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.
