Designation:D604602(Reapproved 2012)Standard Classification ofHydraulic Fluids for Environmental Impact1This standard is issued under the fixed designation D6046;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 classification covers all unused fully formulatedhydraulic fluids in their original form.1.2 This classification establishes categories for the impactof hydraulic fluids on different environmental compartments asshown in Table 1.Fluids are assigned designations within thesecategories;for example PwL,Pwe,and so forth,based onperformance in specified tests.1.3 In the current version of this classification the aspects ofenvironmental impact included are environmental persistenceof which biodegradability is one component and acute ecotox-icity.Although environmental persistence is discussed first,thisclassification does not imply that considerations of environ-mental persistence should take precedence over concerns forecotoxicity.1.4 Another important aspect of environmental impact isbioaccumulation.This aspect is not addressed in the presentclassification because adequate test methods do not yet exist tomeasure bioaccumulation of hydraulic fluids.1.5 The present classification addresses the fresh water andsoil environmental compartments.At this time marine andanaerobic environmental compartments are not included,al-though they are pertinent for many uses of hydraulic fluids.Hydraulic fluids are expected to have no significant impact onthe atmosphere;therefore that compartment is not addressed.1.6 This classification addresses releases to the environmentwhich are incidental to the use of a hydraulic fluid.Theclassification is not intended to address environmental impactin situations of major,accidental release.Nothing in thisclassification should be taken to relieve the user of theresponsibility to properly use and dispose of hydraulic fluids.1.7 This classification does not cover any performanceproperties of a hydraulic fluid which relate to its performancein a hydraulic system.1.8 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.2.Referenced Documents2.1 ASTM Standards:2D5291 Test Methods for Instrumental Determination ofCarbon,Hydrogen,and Nitrogen in Petroleum Productsand LubricantsD5864 Test Method for Determining Aerobic Aquatic Bio-degradation of Lubricants or Their ComponentsD6006 Guide for Assessing Biodegradability of HydraulicFluidsD6081 Practice for Aquatic Toxicity Testing of Lubricants:Sample Preparation and Results InterpretationE943 Terminology Relating to Biological Effects and Envi-ronmental FateE1440 Guide for Acute Toxicity Test with the Rotifer Bra-chionus2.2 ISO Standards:3International Standard ISO Test 9439:1990 Technical Corri-gendum 1,Water QualityEvaluation in An AqueousMedium of the“Ultimate”Biodegradability of OrganicCompoundsMethod by Analysis of Released CarbonDioxide2.3 OECD Standards:4OECD 301B CO2Evolution Test(the Modified Sturm Test)OECD 301C Modified MITI Test(I)OECD 301F Manometric Respirometry TestOECD 201 Alga,Growth Inhibition TestOECD 202 Daphnia sp.,Acute Immobilisation Test andReproduction Test1This classification is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.N0.03 on ECO-Evaluated Fluids.Current edition approved April 15,2012.Published May 2012.Originallyapproved in 1996.Last previous edition approved in 2006 as D604602(2006).DOI:10.1520/D6046-02R12.2For 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 fromAmerican National Standards Institute,25 West 43rd Street,4thFloor,New York,NY 10036.All standards referenced are from the OECDGuidelines for Testing of Chemicals.4Available from Organization for Economic Cooperation and Development(OECD),2,Rue Andre Pascal,S-75775,Paris CEDEX 16,France.May also befound in U.S.Federal Register,Vol 50,No.188,September 27,1965,paragraph796.3260.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 OECD 203 Fish,Acute Toxicity TestOECD 207 Earthworm Acute Toxicity TestOECD 208 Terrestrial Plants Growth Test2.4 US EPA Tests:5Aerobic Aquatic Biodegradation Test,40 CFR 796.3100(Also available as EPA publication 560/6-82-003,numberCG-2000)Toxic Substances Control Act(TSCA),40 CFR Parts 796and 797Environmental
