Designation:D592918Standard Test Method forDetermining Biodegradability of Materials Exposed toSource-Separated Organic Municipal Solid Waste MesophilicComposting Conditions by Respirometry1This standard is issued under the fixed designation D5929;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 biodegradation properties ofa material by reproducibly exposing materials to conditionstypical of source-separated organic municipal solid waste(MSW)composting.A material is composted under controlledconditions using a synthetic compost matrix and determiningthe acclimation time,cumulative oxygen uptake,cumulativecarbon dioxide production,and percent of theoretical biodeg-radation over the period of the test.This test method does notestablish the suitability of the composted product for any use.1.2 This test is performed at mesophilic temperatures.Somemunicipal compost operations reach thermophilic temperaturesduring operation.Thermophilic temperatures can affect thebiodegradation of some materials.This test is not intended toreplicate conditions within municipal compost operations thatreach thermophilic temperatures.1.3 The values stated in both inch-pound and SI units are tobe regarded separately as the standard.The values given inparentheses are for information only.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:2D513 Test Methods for Total and Dissolved Carbon Dioxidein WaterD1129 Terminology Relating to WaterD1293 Test Methods for pH of WaterD2908 Practice for Measuring Volatile Organic Matter inWater by Aqueous-Injection Gas ChromatographyD6247 Test Method for Determination of Elemental Contentof Polyolefins by Wavelength Dispersive X-ray Fluores-cence SpectrometryE1621 Guide for Elemental Analysis by Wavelength Disper-sive X-Ray Fluorescence Spectrometry2.2 APHA-AWWA-WEF Standard Method:32540G Total,Fixed,and Volatile Solids in Solid and Semi-solid Samples3.Terminology3.1 DefinitionsDefinitions of terms applying to this testmethod appear in Terminology D1129.3.2 Definitions of Terms Specific to This Standard:3.2.1 acclimation time,nthe time required for the oxygenuptake to reach 10%of the total measured cumulative oxygenuptake.43.2.2 inoculum,na mixture of organic substances invarying degrees of biodegradation to provide microbial-richsubstrate in which to perform biodegradation testing.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 Feb.1,2018.Published February 2018.Originallyapproved in 1996.Last previous edition approved in 2009 as D5929 96(2009).DOI:10.1520/D5929-18.2For 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 from American Public Health Assoc.,1015 15th Street,NW,Washington,DC 20005,Standard Methods for the Examination of Water and WasteWater,18th ed.,1992.4Tabak,H.H.and Lewis,R.F.,“CEC/OECD Ring Test of Respiration Methodfor Determination of Biodegradability,”U.S.Environmental Protection Agency,pp.13.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 3.2.3 oxygen uptake,nthe cumulative oxygen consumedby the organisms during the test.3.2.4 theoretical carbon dioxide production(ThCO2P),nthe maximum carbon dioxide that can be produced by amaterial as calculated by the carbon content of the material.3.2.5 theoretical oxygen uptake(ThOU),nthe maximumoxygen consumption required to fully oxidize a material basedon the elemental content of the material.3.2.6 virgin newsprintnonprinted newspaper roll stock.4.Test Method4.1 Thi
