Designation:D368719Standard Test Method forAnalysis of Organic Compound Vapors Collected by theActivated Charcoal Tube Adsorption Method1This standard is issued under the fixed designation D3687;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,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.1.Scope1.1 This test method describes the extraction and gaschromatographic determination of organic vapors that havebeen adsorbed from air in sampling tubes packed with acti-vated charcoal.1.2 This test method is complementary to Practice D3686.1.3 This test method is applicable for analysis of samplestaken from workplace or other atmospheres provided that thecontaminant adsorbs onto charcoal,that it can be adequatelyextracted from the charcoal,and that it can be analyzed by gaschromatography(GC).Other adsorbents and other extractiontechniques are described in Practice D6196.1.4 Organic compounds of multicomponent samples maymutually interfere during analysis.Methods to resolve inter-ferences are given in Section 6.1.5 The values stated in SI units are to be regarded asstandard.The values given in parentheses after SI units areprovided for information only and are not considered standard.1.6 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.Specific precautions are given in 8.5,9.2,and in X1.2.3.1.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D1356 Terminology Relating to Sampling and Analysis ofAtmospheresD3686 Practice for Sampling Atmospheres to Collect Or-ganic Compound Vapors(Activated Charcoal Tube Ad-sorption Method)D6196 Practice for Choosing Sorbents,Sampling Param-eters and Thermal Desorption Analytical Conditions forMonitoring Volatile Organic Chemicals in AirE355 Practice for Gas Chromatography Terms and Relation-ships2.2 ISO Standards:3ISO/IEC 17025 General Requirements for the Competenceof Testing and Calibration Laboratories2.3 National Institute for Occupational Safety and Health(NIOSH)Documents:CDC-99-74-45 Documentation of NIOSH Validation Tests4NIOSH Manual of Analytical Methods(NMAM)52.4 Occupational Safety and Health Administration(OSHA)Standards:29 CFR 1910 Code of Federal Regulations,RegulationsRelating to Labor,Occupational Safety and HealthAdministration,Department of Labor61This test method is under the jurisdiction of ASTM Committee D22 on AirQuality and is the direct responsibility of Subcommittees D22.04 on Workplace AirQuality.Current edition approved Aug.1,2019.Published September 2019.Originallyapproved in 1978.Last previous edition approved in 2012 as D3687 07(2012).DOI:10.1520/D3687-19.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from International Organization for Standardization(ISO),ISOCentral Secretariat,BIBC II,Chemin de Blandonnet 8,CP 401,1214 Vernier,Geneva,Switzerland,http:/www.iso.org.4Available from the U.S.Department of Commerce,National Technical Infor-mation Service,5301 Shawnee Road,Alexandria,VA 22312,https:/www.ntis.gov.5Available from the Centers for Disease Control and Prevention(CDC),https:/www.cdc.gov/niosh/nmam.6Available from U.S.Government Printing Office,Superintendent ofDocuments,732 N.Capitol St.,NW,Washington,DC 20401-0001,http:/www.access.gpo.gov.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 OSHA Sampling and Analytical Methods72.5 UK Health and Safety Executive(HSE)Documents:Methods for the Determination of Hazardous Substances(MDHS)83.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this test method,referto the terminology specified in Terminology D1356 and Prac-tice E355.4.Summary of Test Method4.1 Organic vapors that have been collected on activatedcharcoal are extracted with carbon disulfide or another appro-priate solvent and are d
