1、Designation: D 6222 02e1Standard 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 t
2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.e1NOTEEditorial changes were made throughout in July 2005.1. Scope1.1 This specification covers
3、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.1.2 This specification is intended
4、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 est
5、ablish 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 sta
6、ted in SI units are to be regarded as thestandard. The inch-pound units given in parentheses are forinformation only.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 concern
7、s,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.

12、 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.1This specification is under the jurisdiction of ASTM Commi

15、.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 physicalproperties prescribed in Table 1.6.2 The finished pro
16、duct 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, Mass, and Permissible Variations7.1 The finished product shall conform to the followingdimensions and variations:7.1.1 The wid
17、th of the roll shall be as agreed upon betweenthe 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 shal
18、l 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 and Appearance8.1 The finished product shall be completely coated in acontinuous, unbroken film and shall be free of such def
19、ects 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 shall be uniform infinish and texture.8.3 For Grade G products, mineral granules shall be uni-formly distributed over the entire
20、surface of the sheet in aneven layer, excluding any selvage, 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
21、on a smooth plane, the sheet shall bestraight and true so that the selvage will mate with an adjacentsheet, within the tolerance for the lap without wrinkles,buckles, or fishmouths.9. Sampling and Test Methods9.1 Sample the material and determine the properties de-scribed in this specification in ac
