Designation:D1327/D1327M04(Reapproved 2012)1Standard Specification forBitumen-Saturated Woven Burlap Fabrics Used in Roofingand Waterproofing1This standard is issued under the fixed designation D1327/D1327M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1NOTEUnits information was editorially corrected in June 2012.1.Scope1.1 This specification covers woven burlap fabrics,satu-rated with either asphalt or refined coal-tar,as specified by thepurchaser,for use in the membrane system of roofing orwaterproofing or as specified by the manufacturer.1.1.1 Asphalt-saturated burlap fabric shall be used withasphalt base plying cement;typical ones are mopping asphaltsconforming to Specifications D312,D449,or appropriatesolvent-bearing bituminous materials.1.1.2 Coal-tar-saturated burlap fabric shall be used withcoal-tar base plying cements;typical ones are coal-tar pitchesconforming to Specification D450,or appropriate solvent-bearing bituminous materials.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.2.Referenced Documents2.1 ASTM Standards:2D146 Test Methods for Sampling and Testing Bitumen-Saturated Felts and Woven Fabrics for Roofing andWaterproofingD312 Specification for Asphalt Used in RoofingD449 Specification for Asphalt Used in Dampproofing andWaterproofingD450 Specification for Coal-Tar Pitch Used in Roofing,Dampproofing,and WaterproofingD1079 Terminology Relating to Roofing and Waterproofing2.2 AATCC Standard:Method 30-1974 Test for Resistance of Textiles to Mildewand Rot33.Terminology3.1 DefinitionsFor definitions of terms used in this speci-fication,refer to Terminology D1079.4.Materials and Manufacture4.1 The fabric to be saturated shall be composed of 100%jute fiber except for two cotton threads in each selvage.If theselvage is used,it shall be no more than 6 mm 14in.wide.The minimum fabric construction used shall be 180 g/m25.4oz/yd2 minimum burlap.4.2 In the process of manufacture,the dry burlap fabric shallbe saturated with bitumen.5.Physical Properties5.1 The material shall conform to the physical propertiesprescribed in Table 1.5.2 The rolls shall not crack nor be so sticky as to causetearing or material damage upon being unrolled at temperaturesbetween 10 and 60C 50 and 140F.5.3 Resistance to RottingThe average percentage of theoriginal strength retained by the saturated product shall be atleast 1.75 times that retained by the control sample after oneweek.6.Workmanship,Finish,and Appearance6.1 The burlap fabric shall be thoroughly and uniformlysaturated in such a manner that every fiber shall be visiblystained through by the saturant.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 May 1,2012.Published June 2012.Originallyapproved in 1954.Last previous edition approved in 2004 as D1327 04.DOI:10.1520/D1327_D1327M-04R12E01.2For 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 Association of Textile Chemists and Colorists(AATCC),One Davis Dr.,P.O.Box 12215,Research Triangle Park,NC 27709-2215.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 6.2 The meshes of the fabric shall not be completely closedor sealed by the process of saturation.There shall be sufficientporosity maintained to allow successive moppings of theplying cement to seep through.6.3 The surface of the fabric shall not be coated or coveredwith talc or any other substances that would tend to interferewith the adhesion between the fabric and the plying cement.6.4 The surface shall be uniformly smooth and free ofirregularities,folds,and knots.6.5 The finished material shall be free of visible externaldefects,such as ragged or untrue edges,breaks,rents,orcracks.7.Sampling and Test Methods7.1 Sample the material and determine the properties enu-merated in this specification in accordance with Test MethodsD146.7.2 Determine resistance to rotting by the soil burial methoddescribed in Test 1 of AATCC Test Method 30-1974,modifiedas follows:7.2.1 The control sample shall consist of at least fivespecimens of 238 g/m27-oz/1 yd2 untreated
