Designation:D6509/D6509M09(Reapproved 2015)Standard Specification forAtactic Polypropylene(APP)Modified Bituminous BaseSheet Materials Using Glass Fiber Reinforcements1This standard is issued under the fixed designation D6509/D6509M;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.1.Scope1.1 This specification covers prefabricated modified bitumi-nous sheet materials with glass fiber reinforcement,which useatactic polypropylene(APP)as the primary modifier and whichare intended for use as a base sheet in the fabrication ofmultiple ply roofing and waterproofing membranes.1.2 This is a material specification only.Issues regarding thesuitability of specific roof constructions or application tech-niques are beyond the scope of this specification.1.3 The specified tests and property limits used to charac-terize the sheet materials covered by this specification areintended to establish minimum properties.In-place roof systemdesign criteria,such as fire resistance,field strength,impact/puncture resistance,material compatibility,uplift resistance,the need for field applied coatings,and others,are factorsbeyond the scope of this material specification.1.4 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.1.5 The following precautionary statement pertains only tothe test method portion,Section 8,of this specification.Thisstandard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.Referenced Documents2.1 ASTM Standards:2D1079 Terminology Relating to Roofing and WaterproofingD5147 Test Methods for Sampling and Testing ModifiedBituminous Sheet MaterialD5636 Test Method for Low Temperature Unrolling of Feltor Sheet Roofing and Waterproofing Materials3.Terminology3.1 DefinitionsFor definitions of terms used in thisspecification,refer to Terminology D1079.4.Materials and Manufacture4.1 In the manufacturing process,the reinforcement isimpregnated and coated on both sides in an APP-modifiedbituminous coating.The APP-modified bituminous coatingshall be permitted to be compounded with a mineral stabilizer.4.2 The base sheet shall be permitted to be surfaced withmineral matter to prevent sticking in the roll.The reverse sideshall be permitted to be covered with a thin polyolefin film orwith other surfacing that will not interfere with adhesion orbonding of the sheet during application.5.Physical Properties5.1 The sheet shall conform to the minimum physicalproperties described in Table 1.5.2 The finished product shall not crack or be so sticky as tocause tearing or other material damage upon being unrolled atany product temperature between 4 and 60C 40 and140F.6.Dimensions,Mass,and Permissible Variations6.1 The finished product shall conform to the followingdimensions and variations:6.1.1 The width of the roll shall be as agreed upon betweenthe purchaser and the supplier and shall not vary more than1%.1This specification is under the jurisdiction of ASTM Committee D08 and is thedirect responsibility of SubcommitteeD08.04 on Felts,Fabrics and BituminousSheet Materials.Current edition approved Jan.1,2015.Published January 2015.Originallyapproved in 2000.Last previous edition approved in 2009 as D6509/D6509M 09.DOI:10.1520/D6509_D6509M-09R15.2For 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 States1 6.1.2 The area of the roll shall be no less than as agreedupon between the purchaser and the supplier.6.1.3 The selvage width shall be within 6 mm 14in.of thenominal selvage width and shall be not less than 76 mm 3 in.in width from the edge of the sheet.6.2 The mass and thickness of the finished product shall beas prescribed in Table 2.7.Workmanship,Finish,and Appearance7.1 The finished product shall be uniformly impregnatedand coated with atactic polypropylene(APP)-modified bitu-men.It shall be free of visible defects,such as holes,ragged oruntrue edges,breaks,cracks,tears,and protrusions.7.2 When unrolled on a smooth plane,the sheet shall bestraight and true so that the lap will mate with an adjacentsheet,within the tolerance for the lap without wrinkles,bu
