Designation:D368613Standard Practice forSampling Atmospheres to Collect Organic CompoundVapors(Activated Charcoal Tube Adsorption Method)1This standard is issued under the fixed designation D3686;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 practice covers a method for the sampling ofatmospheres to determine the presence of certain organicvapors by means of adsorption on activated charcoal using acharcoal tube and a small portable sampling pump worn by aworker.A list of some of the organic chemical vapors that canbe sampled by this practice is provided in Annex A1.This listis presented as an information guide and should not beconsidered as absolute or complete.1.2 This practice does not cover any method of samplingthat requires special impregnation of activated charcoal orother adsorption media.1.3 The values stated in SI units are to be regarded as thestandard.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 and health practices and determine the applica-bility of regulatory limitations prior to use.A specific safetyprecaution is given in 9.4.2.Referenced Documents2.1 ASTM Standards:2D1356 Terminology Relating to Sampling and Analysis ofAtmospheresD3687 Practice for Analysis of Organic Compound VaporsCollected by the Activated Charcoal Tube AdsorptionMethodD5337 Practice for Flow Rate Adjustment of Personal Sam-pling Pumps2.2 NIOSH Standards:CDC-99-74-45 Documentation of NIOSH Validation Tests3HSM-99-71-31Personal Sampler Pump for CharcoalTubes;Final Report3NIOSH Manual of Analytical Methods,Fourth Edition42.3 OSHA Standards:29 CFR 1910Code of Federal Regulations Relating toLabor,Occupational Safety and Health Administration,Department of Labor5OSHA Chemical Sampling Information6OSHA Sampling and Analytical Methods72.4 UK Health and Safety Executive:8Methods for Determination of Hazardous Substances(MDHS)2.5 Berufsgenossenschaftliches Institut fr Arbeitsschulz(BGIA)9GESTIS Analytical Methods3.Terminology3.1 For definitions of terms used in this method,refer toTerminology D1356.3.2 Activated charcoal refers to properly conditioned char-coal.4.Summary of Practice4.1 Air samples are collected for organic vapor analysis byaspirating air at a known rate and for an appropriate timethrough sampling tubes containing activated charcoal.1This practice is under the jurisdiction ofASTM Committee D22 on Air Qualityand is the direct responsibility of Subcommittee D22.04 on Workplace Air Quality.Current edition approved April 1,2013.Published April 2013.Originallyapproved in 1978.Last previous edition approved in 2008 as D3686-08.DOI:10.1520/D3686-13.2For 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 National Technical Information Service(NTIS),5285 PortRoyal Rd.,Springfield,VA 22161,http:/www.ntis.gov.4NIOSH Manual of Analytical Methods.http:/www.cdc.gov/niosh/nmam/5Available from U.S.Government Printing Office Superintendent of Documents,732 N.Capitol St.,NW,Mail Stop:SDE,Washington,DC 20401,http:/www.access.gpo.gov.6OSHA Chemical Sampling Information.http:/osha.gov/dts/chemicalsampling/toc/toc_chemsamp.html7OSHA Sampling and Analytical Methods.http:/osha.gov/dts/sltc/methods/toc.html8Health Safety Executive.Methods for the Determination of Hazardous Sub-stances(MDHS)guidance.http:/www.hse.gov.uk/pubns/mdhs/index.htm#9Berufsgenossenschaftliches Institut fr Arbeitsschutz.GESTIS Analyticalmethods.http:/www.hvbg.de/e/bia/gestis/analytical_methods/index.htmlCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.2 Instructions are given to enable assembly of charcoaltubes suitable for sampling purposes.4.3 Information on the correct use of the charcoal tubesampling device is presented.4.4 Practice D3687 describes a practice for the analysis ofthese samples.5.Significance and Use5.1 Promulgations by the U.S.Occupational Safety andHealth Administration(OSHA)in 29 CFR 1910.1000 desig-nate that certain organic compounds must not be present inworkplace atmospheres at concentrations above specific val-ues.5.2 This practice,when used in conjunction with PracticeD3687,will provide the needed accuracy and precision for thedetermination of airborne time-weighted average concentra-tions of many of the organic chemicals cited in CDC-99-74-45,HSM-99-71-31,NIOSH Manual of Analytical Methods,29CFR 1910.1000,OSHA Chemical Sampling Information,OSHA Sampling and Analytical Methods,HSE Methods f
