Designation:D6162/D6162M21Standard Specification forStyrene Butadiene Styrene(SBS)Modified BituminousSheet Materials Using a Combination of Polyester and GlassFiber Reinforcements1This standard is issued under the fixed designation D6162/D6162M;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 a combination of polyesterfabric and glass fiber,with or without granules,which usestyrene butadiene styrene(SBS)thermoplastic elastomer as theprimary modifier and are intended for use in the fabrication ofmultiple ply roofing and waterproofing membranes.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 nonconformancewith the standard.1.5 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:2D1079 Terminology Relating to Roofing and WaterproofingD5147/D5147M Test Methods for Sampling and TestingModified Bituminous Sheet Material3.Terminology3.1 DefinitionsFor definitions of terms used in thisspecification,refer to Terminology D1079.4.Classifications4.1 Modified bituminous sheet materials reinforced with acombination of polyester fabric and glass fiber reinforcement,Type I,Type II,and Type III are covered by this specification.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 mineral or any other surfacing that will notinterfere with adhesion or bonding of the lap during applica-tion.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 Dec.1,2021.Published December 2021.Originallyapproved in 1997.Last previous edition approved in 2016 as D6162/D6162M 16.DOI:10.1520/D6162_D6162M-21.2For 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?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 60 C 40 and140 F.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
