Designation:D6222/D6222M16Standard Specification forAtactic Polypropylene(APP)Modified Bituminous SheetMaterials Using Polyester Reinforcements1This standard is issued under the fixed designation D6222/D6222M;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,with orwithout granules,that use atactic polypropylene(APP)as theprimary modifier and are intended for use in the fabrication ofmultiple ply roofing and waterproofing membranes.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 Specification D6223/D6223M.1.2 This specification is intended as a material specificationonly.Issues regarding the suitability of specific roof construc-tions or application techniques are beyond the scope of thisspecification.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 9,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/D5147M Test Methods for Sampling and TestingModified Bituminous Sheet MaterialD5636/D5636M Test Method for Low Temperature Unroll-ing of Felt or Sheet Roofing and Waterproofing MaterialsD6223/D6223M Specification for Atactic Polypropylene(APP)Modified Bituminous Sheet Materials Using aCombination of Polyester and Glass Fiber Reinforcements3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this specification,referto Terminology D1079.4.Classification4.1 Type I and II modified bituminous sheet materialsreinforced with polyester fabric,are covered by this specifica-tion(see Table 1).4.2 The following grades are used to describe the materialsurfacing:4.2.1 Grade GGranule surfacing.4.2.2 Grade SSmooth surfacing.5.Materials and Manufacture5.1 In the process of manufacture,the reinforcement issaturated with APP modified asphalt and is impregnated andcoated on both sides with anAPPmodified bituminous coating.The APP modified bituminous coating shall be permitted to becompounded with a mineral stabilizer.5.2 Grade G materials are surfaced on the weather side withmineral granules,except for any selvage.To prevent sticking in1This 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 Nov.1,2016.Published November 2016.Originallyapproved in 1998.Last previous edition approved in 2011 as D6222/D6222M 11.DOI:10.1520/D6222_D6222M-16.2For 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 the 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 To prevent sticking in the roll,any selvage will besurfaced with mineral or other surfacing material that will notinterfere with adhesion or bonding during application.6.Physical Properties6.1 The sheet shall conform to the minimum physicalpro
