3、ver the determination of nonvola-tile matter in halogenated organic solvents and admixtures.1.2 Five test methods are covered,as follows:1.2.1 Test Method AFor halogenated organic solvents oradmixtures having less than 50 ppm nonvolatile matter;orwhere precision better than 610 ppm is required.1.2.2
4、 Test Method BFor halogenated organic solvents oradmixtures having more than 50 ppm nonvolatile matter orwhere precision of 60.001%(10 ppm)is satisfactory.1.2.3 Test Method CFor low-boiling halogenated organicsolvents or their admixtures(for example,methylene chloride,trichlorotrifluoroethane)that m
5、ay superheat and cause bump-ing while evaporating to dryness with steam.A precision ofgreater than 610 ppm can be attained.1.2.4 Test Method DFor rapid measurement of nonvolatilematter in halogenated organic solvents and their admixturesand where precision better than 610 ppm is required.1.2.5 Test
6、Method EFor halogenated organic solvents oradmixtures and where precision better than 610 ppm isrequired.1.3 The values stated in SI units are to be regarded asstandard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of t
7、he user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established
