Designation:D369496(Reapproved 2017)Standard Practices forPreparation of Sample Containers and for Preservation ofOrganic Constituents1This standard is issued under the fixed designation D3694;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 These practices cover the various means of(1)preparingsample containers used for collection of waters to be analyzedfor organic constituents and(2)preservation of such samplesfrom the time of sample collection until the time of analysis.1.2 The sample preservation practice is dependent upon thespecific analysis to be conducted.See Section 9 for preserva-tion practices listed with the corresponding applicable generaland specific constituent test method.The preservation methodfor waterborne oils is given in Practice D3325.Use of theinformation given herein will make it possible to choose theminimum number of sample preservation practices necessaryto ensure the integrity of a sample designated for multipleanalysis.For further considerations of sample preservation,seethe Manual on Water.21.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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.For specific hazard statements,see 6.7,6.24,and 8.1.3.1.5 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:3D1129 Terminology Relating to WaterD1193 Specification for Reagent WaterD1252 Test Methods for Chemical Oxygen Demand(Di-chromate Oxygen Demand)of WaterD1783 Test Methods for Phenolic Compounds in WaterD2036 Test Methods for Cyanides in WaterD2330 Test Method for Methylene Blue Active Substances(Withdrawn 2011)4D2579 Test Method for Total Organic Carbon in Water(Withdrawn 2002)4D2580 Test Method for Phenols in Water by Gas-LiquidChromatographyD2908 Practice for Measuring Volatile Organic Matter inWater by Aqueous-Injection Gas ChromatographyD3113 Test Methods for Sodium Salts of EDTA in Water(Withdrawn 2005)4D3325 Practice for Preservation of Waterborne Oil SamplesD3371 Test Method for Nitriles in Aqueous Solution byGas-Liquid Chromatography(Withdrawn 2002)4D3534 Test Method for Polychlorinated Biphenyls(PCBs)in Water(Withdrawn 2003)4D3590 Test Methods for Total Kjeldahl Nitrogen in WaterD3695 Test Method for Volatile Alcohols in Water by DirectAqueous-Injection Gas ChromatographyD3856 Guide for Management Systems in LaboratoriesEngaged in Analysis of WaterD3871 Test Method for Purgeable Organic Compounds inWater Using Headspace SamplingD3921 Test Method For Oil and Grease and PetroleumHydrocarbons in Water(Withdrawn 2013)41These practices are under the jurisdiction of ASTM Committee D19 on Waterand are the direct responsibilities of Subcommittee D19.06 on Methods forAnalysisfor Organic Substances in Water.Current edition approved Dec.15,2017.Published December 2017.Originallyapproved in 1978.Last previous edition approved in 2011 as D3694 96(2011).DOI:10.1520/D3694-96R17.2Manual on Water,ASTM STP 442,ASTM International,1969.3For 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.4The last approved version of this historical standard is referenced onwww.astm.org.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 D3973 Test Method for Low-Molecular Weight HalogenatedHydrocarbons in WaterD4129 Test Method for Total and Organic Carbon in Waterby High Temperature Oxidation and by CoulometricDetectionD4165 Test Method for Cyanogen Chloride in WaterD4193 Test Method for Thiocyanate in WaterD4281 Test Method for Oil and Grease(Fluorocarbon Ex-tractable Substances)by Gravimetric Determination(Withdrawn 2012)4D4282 Test Method for Determination of Free Cyanide inWater and Wastewater by Micr
