1、Designation:D210901(Reapproved 2016)Standard Test Methods forNonvolatile Matter in Halogenated OrganicSolvents and Their Admixtures1This standard is issued under the fixed designation D2109;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revi
2、sion,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 These test methods co
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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Terminology2.1 Definitions of Terms Specific to This Standard:2.1.1 The term nonvolatile matter should not be construedas equivalent to residue on
8、ignition,ignition residue,or ashcontent.Particulates,sediments,and suspended matter shouldnot be considered part of nonvolatile matter.If these solids arepresent in the sample,they should be removed by filtration ordecantation prior to beginning this test method.Nonvolatilematter is considered to be
9、“in solution”with the solvent andthat which will become residual upon drying the solvent at aspecified temperature.2.1.2 Nonvolatile matter and nonvolatile residue are inter-changeable terms.3.Significance and Use3.1 Nonvolatile matter in solvents can adversely affect theircleaning properties.These
10、test methods can be used to controlsoil contamination in the boiling solvent,which if allowed tobecome too high,can decrease the stability of the solvent.3.2 These test methods can be used to establish manufac-turing and purchasing specifications.4.Apparatus4.1 Oven,thermostatically controlled at 10

15、 dish in an oven at 105 6 5C and cool in adesiccator.Repeat until the weight is constant or within 0.1 mgof the last weighing.Rinse a clean dry 1000-mL volumetricflask with the solvent and fill to the 1000-mL mark with thesolvent to be tested.Invert the evaporating dish,place it overthe mouth of the
16、 flask,hold it firmly in place,and invert theflask.In this position place both dish and flask on a steam bath.Adjust a ring support to hold the flask so the mouth of the flaskis approximately 25 mm above the bottom of the evaporatingdish.Thus held,the flask automatically feeds the solvent to thedish during the evaporation.(WarningThis test methodmust be run in a ventilated,dust-free area.)5.2 Evaporate the 1000-mL sample to dryness.Remove thedish from the steam bath with metal tongs and blot the
