Designation:D7530/D7530M10Standard Specification forSelf-Adhesive Glass Fiber Fabric Reinforced PolymerModified Asphalt Steep Slope Roll Roofing Surfaced withMineral Granules1This standard is issued under the fixed designation D7530/D7530M;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,self-adhesive,glass fiber fabric reinforced,polymer-modified asphalt rollroofing,with granule surfacing,designed for steep slopeapplications.These products use polymer modifiers in their topand bottom coatings.These products have an adhesive bottomlayer which is exposed by removal of a peel-away protectiverelease paper or film sheet.1.2 The specified tests and property limits used to charac-terize the sheet materials are intended to establish minimum,ormaximum properties.In-place roof system design criteria,suchas fire resistance,field strength,impact/puncture resistance,material compatibility,uplift resistance,and others,are factorsbeyond the scope of this material specification.Factors regard-ing the suitability of specific roof constructions or applicationtechniques are beyond this scope.1.3 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.1.4 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D903 Test Method for Peel or Stripping Strength of Adhe-sive BondsD1079 Terminology Relating to Roofing and WaterproofingD4977 Test Method for Granule Adhesion to Mineral Sur-faced Roofing by AbrasionD5147 Test Methods for Sampling and Testing ModifiedBituminous Sheet Material3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this specification,referto Terminology D1079.3.1.2 ultimate elongation,nthe elongation measured onthe load-elongation curve at which point the load has droppedto 5%of its maximum value.4.Materials and Manufacture4.1 In the process of manufacture,the reinforcing mat isimpregnated and coated on its top and bottom sides withpolymer modified asphalt coatings.The polymer modifiedasphalt coatings are permitted to be compounded with amineral stabilizer.The coating on the bottom side shall featureself-adhesive properties.4.2 The sheet is surfaced on the weather side with mineralgranules,except for any selvage.5.Physical Properties5.1 The sheet shall conform to the minimum physicalproperties prescribed in Table 1.5.2 The finished product shall not crack nor be so sticky asto cause tearing or other material damage upon being unrolledat any product temperature between 4 and 60C 40 and 140F1This specification is under the jurisdiction of ASTM Committee D08 onRoofing and Waterproofing and is the direct responsibility of Subcommittee D08.02on Steep Roofing Products and Assemblies.Current edition approved July 1,2010.Published July 2010.DOI:10.1520/D7530_D75305M10.2For 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 or at a lower temperature if the manufacturer allows applica-tion at such lower temperature.5.3 The release paper,or film sheet,shall not tear duringremoval.6.Dimensions and Permissible Variations6.1 The width and area of the finished product shall conformto the following:6.1.1 The width of the roll shall be as agreed between thepurchaser and the seller and shall not vary more than 1%.6.1.2 The area of the roll shall be no less than as agreedbetween the purchaser and the seller.7.Workmanship,Finish,and Appearance7.1 The reinforcement shall be coated completely in acontinuous,unbroken film and shall be free of such defects asholes,tears,cracks,wrinkles,or permanent deformations,blisters,ragged or untrue edges,and areas of uncoated rein-forcement.7.2 The surface of the weather side,exclusive of anyselvage,shall be uniform in finish and texture.7.3 The mineral granules shall be distributed in a uniformlayer over the entire surface,excluding any selvage,and shallbe embedded firmly in the polymer modified asphalt coating.The line of demarcation between the granule-surfaced portionof the weather side and any selv
