Designation:D590598(Reapproved 2018)Standard Practice forthe Preparation of Substitute Wastewater1This standard is issued under the fixed designation D5905;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 the preparation of an aqueousmixture containing constituents in concentrations such that itwill have physical and chemical matrix characteristics similarto municipal wastewater.1.2 Wastewaters are extremely variable,depending on thequantity and nature of the materials being discharged into thecollection system.The mixture prepared with this practice isnot representative of any particular wastewater.Rather,itallows the user to prepare a mixture that exhibits a similarmatrix impact on test method performance as is typical ofmunicipal wastewater and can be prepared from commonmaterials inexpensively and reproducibly.It allows the evalu-ation of test methods,over time,against the same referencepoint.1.3 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.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:2D1129 Terminology Relating to WaterD1141 Practice for the Preparation of Substitute OceanWaterD1193 Specification for Reagent WaterD2777 Practice for Determination of Precision and Bias ofApplicable Test Methods of Committee D19 on Water3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this standard,refer toTerminology D1129.3.2 Definitions of Terms Specific to This Standard:3.2.1 substitute wastewater,na mixture of dissolved andsuspended materials in water,typical of the influent to amunicipal wastewater treatment facility.4.Significance and Use4.1 Substitute wastewater may be used for laboratory testingwhere a reproducible mixture simulating municipal wastewateris required.To provide a more rugged evaluation of a testmethods ability to measure analytes and the precision of thetest method under more demanding conditions,it is necessaryto utilize a matrix more complex than reagent water.Substitutewastewater is intended to be used as a material to be spikedwith analytes or interferents of interest to evaluate the perfor-mance of test methods.4.2 Utilization of substitute wastewater as a matrix ininterlaboratory validation studies will allow inclusion of per-formance statistics for this matrix in the Precision and Biassection of test methods.Users of test methods will be able toevaluate their application of test methods in this matrix againstpublished results.5.Apparatus5.1 Blender,household or commercial variety,with a chemi-cally inert container and a tight sealing lid.6.Reagents6.1 Purity of ReagentsReagent grade chemicals shall beused in all tests.Unless otherwise indicated,it is intended thatall reagents conform to the specifications of the Committee onAnalytical Reagents of the American Chemical Society where1This practice is under the jurisdiction of ASTM Committee D19 on Water andis the direct responsibility of Subcommittee D19.02 on Quality Systems,Specification,and Statistics.Current edition approved Dec.1,2018.Published December 2018.Originallyapproved in 1996.Last previous edition approved in 2013 as D5905 98(2013).DOI:10.1520/D5905-98R18.2For 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.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 such specifications are available.3Other grades may be used,provided it is first ascertained that the reagent is of sufficientlyhigh purity to permit its use without lessening the accuracy ofdetermination.6.2 Purity of WaterUnless otherwise indicated,referencesto water sh
