1、Designation:D460022Standard Test Method forDetermination of Benzene-Soluble Particulate Matter inWorkplace Atmospheres1This standard is issued under the fixed designation D4600;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year
2、 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.1.Scope1.1 This test method describes the sampling and gravimetricdetermination of benzene-soluble particulate matter that hasbeco
3、me airborne as a result of certain industrial processes.Thistest method can be used to determine the total weight ofbenzene-soluble materials and to provide a sample that may beused for specific and detailed analyses of the soluble compo-nents.1.2 The limit of detection is 0.05 mg/m3by sampling a 1
4、m3volume of air.NOTE1Other volatile organic solvents have been used for thisdetermination and whereas a less toxic solvent for this analysis might bedesirable,the substitution of a solvent other than benzene is unwise at thistime.A tremendous volume of environmental sampling data based onbenzene-sol
5、uble determinations has been accumulated over many years inseveral industries.2Some of the determinations have been used inepidemiological studies.Furthermore,the use of benzene is specified inexisting United States federal standards.3As a result,it appears imprudentto use a different solvent until
6、the qualitative and quantitative relationshipof analyses derived from benzene and a substitute solvent is established.With proper care,benzene can be safely used in the laboratory.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstanda
7、rd.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the 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
