Designation:D597517Standard Test Method forDetermining the Stability of Compost by Measuring OxygenConsumption1This standard is issued under the fixed designation D5975;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 test method covers the stability of a compostsample by measuring oxygen consumption after exposure ofthe test compost to a well-stabilized compost under controlledcomposting conditions on a laboratory scale involving activeaeration.This test method is designed to yield reproducible andrepeatable results under controlled conditions that resemble theend of the active composting phase.The compost samples areexposed to a well-stabilized compost inoculum that is preparedfrom the organic fraction of municipal solid waste or wastesimilar to the waste from which the test materials are derived.The aerobic composting takes place in an environment wheretemperature,aeration,and humidity are monitored closely andcontrolled.1.2 This test method yields a cumulative amount of oxygenconsumed/g of volatile solids in the samples over a four-dayperiod.The rate of oxygen consumption is monitored as well.1.3 This test method is applicable to different types ofcompost samples including composts derived from wastes,such as municipal solid waste,yard waste,source-separatedorganics,biosolids,and other types of organic wastes that donot have toxicity levels that are inhibitory to the microorgan-isms present in aerobic composting systems.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 There is no similar or equivalent ISO method.1.6 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.Specific hazard statements are given in Section 8.1.7 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:2D883 Terminology Relating to PlasticsD1293 Test Methods for pH of WaterD2908 Practice for Measuring Volatile Organic Matter inWater by Aqueous-Injection Gas ChromatographyD3590 Test Methods for Total Kjeldahl Nitrogen in WaterD4129 Test Method for Total and Organic Carbon in Waterby High Temperature Oxidation and by CoulometricDetectionD5338 Test Method for Determining Aerobic Biodegrada-tion of Plastic Materials Under Controlled CompostingConditions,Incorporating Thermophilic TemperaturesD5907 Test Methods for Filterable Matter(Total DissolvedSolids)and Nonfilterable Matter(Total Suspended Solids)in WaterD8001 Test Method for Determination of Total Nitrogen,Total Kjeldahl Nitrogen by Calculation,and Total Phos-phorus in Water,Wastewater by Ion Chromatography2.2 APHA-AWWA-WPCF Standards:32540 D Total Suspended Solids Dried at 103105 C2540 E Fixed and Volatile Solids Ignited at 550 C3.Terminology3.1 Definitions of terms in this test method appear inTerminology D883.4.Summary of Test Method4.1 This test method consists of the following:4.1.1 Selecting a compost sample for the determination ofthe stability.1This test method is under the jurisdiction of ASTM Committee D34 on WasteManagement and is the direct responsibility of Subcommittee D34.03 on Treatment,Recovery and Reuse.Current edition approved Dec.1,2017.Published December 2017.Originallyapproved in 1996.Last previous edition approved in 2010 as D5975 96(2010).DOI:10.1520/D5975-17.2For 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.3Standard Methods for the Examination of Water and Wastewater,17th Edition,1989,American Public Health Association,1740 Broadway,New York,NY,19919.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 4.1.2 Producing a fully stabilized compost from a similarwaste stream under well-controlled laboratory conditions.4.1.3 Exposing the compost test sa
