1、Designation: D6222/D6222M 11Standard 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 adoptio
2、n 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 material
3、s 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.NOTE 1Many modified bituminous sheets are currently marketedwith polyester mat reinf
4、orced with glass yarns to improve processing inthe manufacture 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 fin
5、ished product so much as to make theseproducts be classified by Specification D6223.1.2 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 specifi
6、ed 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 nee
7、d 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 use
8、d 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,i
9、f 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.

Physical Properties6.1 The sheet shall conform to the minimum physicalproperties prescribed in Table 1.6.2 The finished product shall not crack or be so sticky as tocause
18、 tearing or other material damage upon being unrolled atany product temperature between 4 and 60C 40 and 140F.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 upon betweenthe
19、 purchaser and the supplier and shall not vary more than1%.7.1.2 The area of the roll shall be no less than as agreedupon between the purchaser and the supplier.7.1.3 The selvage width shall be within 6 mm 14 in. of thenominal selvage width and shall be not less than 76 mm 3 in.in width from the edg
20、e of the sheet.7.2 The mass and thickness of the finished product shall beas prescribed in Table 2.8. Workmanship, Finish and Appearance8.1 The finished product shall be completely coated in acontinuous, unbroken film and shall be free of such defects asholes, tears, cracks, wrinkles or permanent de
21、formations,blisters, ragged or untrue edges, and areas of uncoated rein-forcement.8.2 The surface of the weather side shall be uniform infinish and texture.8.3 For Grade G products, mineral granules shall be uni-formly distributed over the entire surface of the sheet in aneven layer, excluding any s
22、elvage, and shall be firmly embed-ded in the APP modified bituminous coating. The line ofdemarcation between the granule surfaced portion of theweather side and any selvage shall be straight and parallel tothe edges of the sheet.8.4 When unrolled on a smooth plane, the sheet shall bestraight and tru
