1、Designation: D 6164 05Standard Specification forStyrene Butadiene Styrene (SBS) Modified BituminousSheet Materials Using Polyester Reinforcements1This standard is issued under the fixed designation D 6164; the number immediately following the designation indicates the year oforiginal adoption or, in
2、 the 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.1. Scope1.1 This specification covers prefabricated modified bitumi-nous sheet materials reinf
3、orced with polyester fabric as theprimary reinforcement, (see Note 1) with or without granules,which use styrene butadiene styrene (SBS) thermoplasticelastomer as the primary modifier and are intended for use inthe fabrication of multiple ply roofing and waterproofingmembranes.NOTE 1Many modified bi
4、tuminous sheets are currently marketedwith polyester mat reinforced 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 reinforcem
5、ent and do not contributeto the physical properties of the finished product so much as to make theseproducts be classified by D 6162.1.2 This specification is intended as a material specificationonly. Issues regarding the suitability of the specific roofconstructions or application techniques are be
6、yond 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 o
7、thers, are factors beyondthe scope of this material specification.1.4 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.2.

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
16、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:7.1.1 The width of the roll shall be as agreed between thepurc
17、haser 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 (14 in.) ofthe nominal selvage width and shall be not less than 76.2 mm(3 in.) in width without a laying
18、 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
19、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 rein-forcement.8.2 The surface of the weather side shall be uniform infinish
20、 and texture.8.3 For Grade G material, the mineral granules shall bedistributed uniformly over the entire surface in an even layerexcluding any selvage, shall be embedded firmly in the SBSmodified bituminous coating, and the line of demarcationbetween the granule-surfaced portion of the weather side
21、 andany selvage shall be straight and parallel to the edges of thesheet.8.4 When unrolled on a smooth plane, the sheet shall bestraight and true so that the lap will mate with the adjacentsheet within the tolerance for the lap without wrinkles, buckles,or fishmouths.9. Sampling and Test Methods9.1 S
