Designation:D6164/D6164M11Standard Specification forStyrene Butadiene Styrene(SBS)Modified BituminousSheet Materials Using Polyester Reinforcements1This standard is issued under the fixed designation D6164/D6164M;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 reinforced with polyester fabric as theprimary reinforcement,(see Note 1)with or without granules,which use styrene butadiene styrene(SBS)thermoplasticelastomer as the primary modifier and are intended for use inthe fabrication of multiple ply roofing and waterproofingmembranes.NOTE1Many modified bituminous sheets are currently marketed withpolyester mat reinforced with glass yarns to improve processing in themanufacture of the finished modified bitumen product and to reducedistortions that may be introduced during production.These glass yarnsare typically a small percentage of the reinforcement and do not contributeto the physical properties of the finished product so much as to make theseproducts be classified by D6162.1.2 This specification is intended as a material specificationonly.Issues regarding the suitability of the specific roofconstructions or application techniques are beyond this scope.1.3 The specified tests and property limits used to charac-terize the sheet materials are intended to establish minimumproperties.In-place roof system design criteria,such as fireresistance,field strength,impact/puncture resistance,materialcompatibility,uplift resistance,and others,are factors beyondthe 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.2.Referenced Documents2.1 ASTM Standards:2D1079 Terminology Relating to Roofing and WaterproofingD5147 Test Methods for Sampling and Testing ModifiedBituminous Sheet MaterialD6162 Specification for Styrene Butadiene Styrene(SBS)Modified Bituminous Sheet Materials Using a Combina-tion of Polyester and Glass Fiber Reinforcements3.Terminology3.1 DefinitionsFor definitions of terms used in this speci-fication,refer to Terminology D1079.4.Classification4.1 Modified bituminous sheet materials reinforced withpolyester fabric,Type I and Type II,are covered by thisspecification.4.2 The following grades are used to describe the materialsurfacing:4.2.1 Grade GGranule Surfaced.4.2.2 Grade SSmooth Surfaced.5.Material and Manufacture5.1 In the process of manufacture,the reinforcement issaturated with asphalt or modified asphalt and is impregnatedand coated on both sides with an SBS modified bituminouscoating.The SBS modified bituminous coating shall be per-mitted to be compounded with a mineral stabilizer.5.2 The Grade G sheet is surfaced on the weather side withmineral granules,except for any selvage.To prevent sticking inthe roll,the reverse side and any selvage shall be permitted tobe covered with a fine mineral surfacing or any other surfacingthat will not interfere with adhesion or bonding of the lapduring application.5.3 Sheet material intended for application by heat welding(torching)shall meet the minimum bottom coating requirementfound in Table 1.6.Physical Properties6.1 The sheet shall conform to the minimum physicalproperties prescribed in Table 2.6.2 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 and140F.1This specification is under the jurisdiction ofASTM CommitteeD08 on Roofingand Waterproofing and is the direct responsibility of Subcommittee D08.04 on Feltsand Fabrics.Current edition approved Jan.1,2011.Published January 2011.Originallyapproved in 1997.Last previous edition approved in 2005 as D6164 051.DOI:10.1520/D6164_D6164M-11.2For 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 7.Dimensions,Mass,and Permissible Variations7.1 The finished product shall conform to the followingdimensions and variations:7.1.1 The width of the roll shall be as agreed between thepurchaser and the seller and shall not vary more than 1%.7.1.2 The area of the roll shall be no less than as agreedbetween the purchaser and the seller.7.1.3 The selvage width shall be within 6.4 mm 14in.ofthe nominal selvage width
