Designation:D 6094 97(Reapproved 2004)Standard Guide toAssess the Compostability of Environmentally DegradableNonwoven Fabrics1This standard is issued under the fixed designation D 6094;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(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide covers suggested criteria,procedures,and ageneral approach to establish the compostability of environ-mentally degradable nonwoven fabrics and products.NOTE1The assessment of degradable plastics and nonwoven fabricsor products is considered similar.Consequently,this guide contains onlyminor changes in technical content from this guide developed bySubcommittee D20.96 on Environmentally Degradable Plastics of Com-mittee D-20 on Plastics.1.2 The values stated in SI units are to be regarded as thestandard.The inch-pound units given in parentheses are forinformation only.1.3 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:2D 123 Terminology Relating to TextilesD 883 Terminology Relating to PlasticsD 1776 Practice for Conditioning Textiles for TestingD 3593 Test Method for Molecular Weight and MolecularDistribution of Certain Polymers by Liquid Size ExclusionChromatography(GPC)Using Universal CalibrationD 3776 Test Methods for Mass per Unit Area(Weight)ofWoven FabricsD 3786 Test Method for Hydraulic Bursting Strength ofKnitted Goods and Nonwoven Fabrics-Diaphragm Burst-ing Strength Tester MethodD 5034 Test Method for Breaking Strength and Elongationof Textile Fabrics(Grab Test)D 5152 Practice for Water Extraction of Residual Solidsfrom Degraded Plastics for Toxicity TestingD 5209 Test Method for Determining the Aerobic Biodeg-radation of Plastic Materials in the Presence of MunicipalSewer SludgeD 5247 Test Method for Determining the Aerobic Biode-gradability of Degradable Plastics by Specific Microorgan-ismsD 5338 Test Method for Determining Aerobic Biodegrada-tion of Plastic Materials Under Controlled CompostingConditionsD 5509 Practice for Exposing Plastics to a Simulated Com-post EnvironmentD 5512 Practice for Exposing Plastics to a Simulated Com-post Environment Using an Externally Heated ReactorD 5734 Test Method for Tearing Strength of NonwovenFabrics by Falling-Pendulum(Elmendorf)ApparatusD 5988 Test Method for Determining the Aerobic Biodeg-radation In Soil of Plastic Materials or Residual PlasticMaterials After CompostingD 5951 Practice for Preparing Residual Solids ObtainedAfter Biodegradation Standard Methods for Plastics inSolid Waste for Toxicity and Compost Quality TestingD 6002 Guide toAssess the Compostability of Environmen-tally Degradable PlasticsE 1440 Guide for an Acute Toxicity Test with the RotiferBrachionus(and with Microcrustacean Thamnocelphalus)E 1720 Test Method for Determining Ready,Ultimate,Bio-degradability of Organic Chemicals in a Sealed Vessel CO2Production TestG 22 Practice for Determining Resistance of SyntheticPolymeric Materials to Bacteria2.2ORCA Standard:Guidelines for the Evaluation of Feedstock for SourceSeparated Biowaste Composting and Biogasification,199432.3OECD Standards:OECD Guideline 207,Earthworm,Acute Toxicity Tests4OECD Guideline 208,Terrestrial Plants,Growth Test41This guide is under the jurisdiction of ASTM Committee D13 on Textiles andis the direct responsibility of Subcommittee D13.64 on Non-Woven Fabric.Current edition approved May 10,1997.Published September 1997.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandardsvolume information,refer to the standards Document Summary page onthe ASTM website.3Organic Reclamation and Composting Association(ORCA),Avenue E.Mou-nier 83,Box 1,B-1200 Brussels,Belgium.4Organization for Economic Development(OECD),OECD Guidelines forTesting of Chemicals,Available from Director of Information,2 rue Andr Pascal,75775 Paris Cedex 16,France.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.2.4Other Documents:Guidelines for the Use of Environmental Marketing Claims,19925Towards Common Ground,The International Workshop onBiodegradability,199262.5Compositing Documents:Compost Facility Operating Guide,19957Recommended Test Methods for the Examination of Com-post and Composting7U.S.Solid Waste Composting Facility ProfilesVolume II,199383.Terminology3.1 Definitions:3.1.1 biodegradable material,na material in which thedegradation results from the action of naturally occurringmicro-organisms such as bacteria,fungi and algae.3.1
