1.2.1 Test Method A-For halogenated organic solvents or admixtures having less than 50 ppm nonvolatile matter; or where precision better 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 admixtures and where precision better than ±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.
