Designation:D600617Standard Guide forAssessing Biodegradability of Hydraulic Fluids1This standard is issued under the fixed designation D6006;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.Scope*1.1 This guide covers and provides information to assist inplanning a laboratory test or series of tests from which may beinferred information about the biodegradability of an unusedfully formulated hydraulic fluid in its original form.Biode-gradability is one of three characteristics which are assessedwhen judging the environmental impact of a hydraulic fluid.The other two characteristics are ecotoxicity and bioaccumu-lation.1.2 Biodegradability may be considered by type of environ-mental compartment:aerobic fresh water,aerobic marine,aerobic soil,and anaerobic media.Test methods for aerobicfresh water,aerobic soil and anaerobic media have beendeveloped that are appropriate for the concerns and needs oftesting in each compartment.1.3 This guide addresses releases to the environment thatare incidental to the use of a hydraulic fluid but is not intendedto cover situations of major,accidental release.The testsdiscussed in this guide take a minimum of three to four weeks.Therefore,issues relating to the biodegradability of hydraulicfluid are more effectively addressed before the fluid is used,and thus before incidental release may occur.Nothing in thisguide should be taken to relieve the user of the responsibilityto properly use and dispose of hydraulic fluids.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 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:2D5210 Test Method for Determining the Anaerobic Biodeg-radation of Plastic Materials in the Presence of MunicipalSewage Sludge(Withdrawn 2016)3D5291 Test Methods for Instrumental Determination ofCarbon,Hydrogen,and Nitrogen in Petroleum Productsand LubricantsD5480 Test Method for Engine Oil Volatility by Gas Chro-matography(Withdrawn 2003)3D5864 Test Method for Determining Aerobic Aquatic Bio-degradation of Lubricants or Their ComponentsE1196 Test Method for Determining the Anaerobic Biodeg-radation Potential of Organic Chemicals(Withdrawn1998)32.2 ISO Standards:ISO 9439:1990 Technical Corrigendum I,Water Quali-tyEvaluation in an Aqueous Medium of the UltimateBiodegradability of Organic Compounds4ISO 4259:1992(E)Petroleum ProductsDetermination andApplication of Precision Data in Relation to Methods ofTest42.3 OECD Standards:OECD 301B(the Modified Sturm Test)Guidelines forTesting Chemicals5OECD 301F(the Manometric Respirometry Test)Guide-lines for Testing of Chemicals53.Terminology3.1 Definitions:1This guide is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.12 on Environmental Standards for Lubricants.Current edition approved Jan.1,2017.Published February 2017.Originallyapproved in 1996.Last previous edition approved in 2011 as D6006 11.DOI:10.1520/D6006-17.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.5Available from Organisation for Economic Co-Operation and Development(OECD),2,rue Andr Pascal,F-75775 Paris Cedex 16,France.*A Summary of Changes section appears at the end of this standardCopyright 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 3.1.1 aerobic,adj1.taking place in the presence ofoxygen;2.living or active in the presence of oxygen.3.1.2 anaerobic,adj1.taking place in the absence ofoxygen;2.living or active in the absence of oxygen.3.1.3 biodegradation,nthe process of chemical break-down or transformation of a material caused by organisms ortheir enzymes.3.1.3.1 DiscussionBiodegradation is only one mechanismby which materials
