1、Designation: D7505/D7505M 10Standard Specification forSelf-Adhesive Polyester Fabric Reinforced Polymer ModifiedAsphalt Steep Slope Roll Roofing Surfaced with MineralGranules1This standard is issued under the fixed designation D7505/D7505M; the number immediately following the designation indicates
2、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, self-ad
3、hesive,polyester fabric reinforced, polymer-modified asphalt surfacedroll roofing products, with granule surfacing, designed forsteep slope applications. These products use polymer modifiersin their top and bottom coatings. These products have anadhesive bottom layer which is exposed by removal of a
4、peel-away protective release paper or film sheet.1.2 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, materialcompat
5、ibility, uplift resistance, and others, are factors beyondthe scope of this material specification. Factors regarding thesuitability of specific roof constructions or application tech-niques are beyond this scope.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separate
6、ly 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.1.4 This standard does not purport to address all of thesafety concerns, i
7、f any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

This rate, which provides a laminate sepa-ration rate of 25 mm 1 in./min 63 %, shall be uniformthroughout the test.8.4.4 Procedure:8.4.4.1 Separate the free end of the sheet from the plywoodfor a distance of about 50 mm 2 in
32、. leaving about 75 mm 3in. of bonded length. Place the specimen in the testingmachine by clamping the free end of the plywood in the fixedgrip, turning back the free end of the sheet and clamping it inthe other grip. Maintain the specimen in the approximate planeof the clamps during the test. Peel a

43、hesive sheetand place the sheet on the plywood. Roll the sheet as describedin 8.4.2.2. Place the second sheet (with release film partiallypeeled off only to expose bottom coating to cover just theselvage) over the selvage positioned in a way to allow 25 mm1 in. 65 % of the salvage below to be expose
44、d per Fig. 1 andpress down the edges of the sheet manually with fingerpressure just hard enough to keep them from lifting. Roll overthe lap as specified in 8.4.2.2. The top sheet must only beadhered over the selvage, and must be loose over plywood pastthe selvage area.8.6.3.2 Cut the bottom out of a
45、 4-L 1-gal can with a canopener and center it, bottom side down, on the membranecentering it with the inner edge of the salvage. Apply a 6-mm0.25-in. bead of silicone sealant completely around theoutside rim of the can to bond it to the membrane. As shown inFig. 1, apply the bead of caulk around all
46、 three edges of theupper membrane until the end of the salvage area. Allow 2 hfor the sealant to set, then apply another bead around the insiderim of the can.8.6.3.3 After waiting 24 h at ambient temperature for thesealant caulking to cure, fill the can to a depth of 125 mm 5in. with deionized or di
