Designation:D6163/D6163M00(Reapproved 2015)1Standard Specification forStyrene Butadiene Styrene(SBS)Modified BituminousSheet Materials Using Glass Fiber Reinforcements1This standard is issued under the fixed designation D6163/D6163M;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.1NOTEUnits information was editorially corrected in January 2015.1.Scope1.1 This specification covers prefabricated modified bitumi-nous sheet materials with glass fiber reinforcement,with orwithout granules,that use styrene butadiene styrene(SBS)thermoplastic elastomer as the primary modifier and areintended for use in the fabrication of multiple ply roofing andwaterproofing 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 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 Material3.Terminology3.1 DefinitionsFor definitions of terms used in thisspecification,refer to Terminology D1079.4.Classifications4.1 Modified bituminous sheet materials reinforced withglass fiber,Type I,Type II,and Type III 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 isimpregnated and coated on both sides with an SBS modifiedbituminous coating.The SBS modified bituminous coatingshall be permitted 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.7.Dimensions,Mass,and Permissible Variations7.1 The finished product shall conform to the followingdimensions and variations: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 Jan.1,2015.Published February 2015.Originallyapproved in 1997.Last previous edition approved in 2008 as D6163 00(2008).DOI:10.1520/D6163_D6163M-00R15E01.2For 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 7.1.1 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 and shall be not less than 76.2 mm3 in.in width without a laying line and 63.5 mm 2.5 in.inwidth if the sheet has a laying line.If a laying line is provided,the line must not be less than 76.2 mm 3 in.from the edge ofthe sheet.7.2 The mass and thickness of the finished product shall beas prescribed in Table 1.8.Workmanship,Finish,and Appearance8.1 The finished product 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
