1、Designation: D 6222 08Standard Specification forAtactic Polypropylene (APP) Modified Bituminous SheetMaterials Using Polyester Reinforcements1This standard is issued under the fixed designation D 6222; the number immediately following the designation indicates the year oforiginal adoption or, in the
2、 case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers prefabricated modified bitumi-nous sheet materials reinforced
3、 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 reinforced with g

Issues regarding the suitability of specific roof construc-tions or application techniques are beyond the scope of thisspecification.1.3 The specified tests an
6、d 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

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 tearing or other material damage upon being unrolled atany product temperature between 4 and 60C (40 and 140F).7. Dimensions, M

19、een 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 edge of the sheet.7.2 The mass and thickness of the finished product shall beas prescribed in Table 2.8. Workmanship, Finish
20、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 deformations,blisters, ragged or untrue edges, and areas of uncoated rein-forcement.8.2 The surface of the weather side shal
