Designation:D227/D227M03(Reapproved 2018)Standard Specification forCoal-Tar-Saturated Organic Felt Used in Roofing andWaterproofing1This standard is issued under the fixed designation D227/D227M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.This specification replaces Federal specification HH-R-595,Type 15C.1.Scope1.1 This specification covers coal-tar-saturated organic feltintended to be used with coal-tar pitches conforming to theappropriate requirements of Specification D450/D450M in theconstruction of built-up roofs and in the construction ofwaterproofing systems.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 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:2D146/D146M Test Methods for Sampling and TestingBitumen-Saturated Felts and Woven Fabrics for Roofingand WaterproofingD450/D450M Specification for Coal-Tar Pitch Used inRoofing,Dampproofing,and WaterproofingD1079 Terminology Relating to Roofing and Waterproofing3.Terminology3.1 DefinitionsFor definitions of terms used in thisspecification,refer to Terminology D1079.4.Materials and Manufacture4.1 In the process of manufacture,a single thickness of dryfelt shall be saturated with refined coal-tar from which some ofthe more volatile constituents have been removed.4.2 The felt shall be produced principally from organicfibers or mixtures thereof.The surface of the felt shall beuniform and relatively smooth.Upon splitting or tearing on thebias,the felt shall appear reasonably free of lumps and particlesof foreign substances.5.Physical Requirements5.1 The material shall conform to the physical requirementsprescribed in Table 1.5.2 The finished product shall not crack nor be so sticky asto cause tearing or other damage upon being unrolled attemperatures between 10 and 60C 50 and 140F.6.Workmanship,Finish,and Appearance6.1 The felt shall be saturated and shall show no unsaturatedspots at any point upon cutting 50-mm 2-in.wide strips atrandom across the entire sheet and splitting them open to theirfull length.6.2 The surface of the felt shall not be coated or coveredwith talc or other substances that would tend to interfere withadhesion between the felt and the plying cement.6.3 The finished material shall be free of visible externaldefects such as holes,ragged or untrue edges,breaks,cracks,tears,protuberances,and indentations.7.Sampling and Test Methods7.1 Sample the material and determine the properties enu-merated in this specification in accordance with Test MethodsD146/D146M.8.Inspection8.1 InspectionInspection shall be in accordance with therequirements of this specification.1This specification is under the jurisdiction of ASTM Committee D08 onRoofing and Waterproofing and is the direct responsibility of Subcommittee D08.04on Felts,Fabrics and Bituminous Sheet Materials.Current edition approved Sept.1,2018.Published October 2018.Originallyapproved in 1925.Last previous edition approved in 2011 as D227/D227M 03(2011)1.DOI:10.1520/D0227_D0227M-03R18.2For 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.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 8.2 Inspection AlternativesAlternative inspection require-ments shall be determined by and as agreed upon between thepurchaser and the supplier.9.Rejection and Resubmittal9.1 Failure to ConformFailure to conform to any of therequirements as stated in this specification constitutes groundsfor rejection.9.2 Rejection RedressThe supplier shall have the right toinspect the rejected materials.The supplier and the purchasershall agree to the quantity of rolls deemed unacceptable.Th
