1、Designation: D7505/D7505M 17Standard 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.1.5 This international standard was developed in accor-dance with internationally recogni

Place the specimen in the testingmachine by clamping the free end of the plywood in the fixedgrip, turning back the free end of
35、 the sheet and clamping it inthe other grip. Maintain the specimen in the approximate planeof the clamps during the test. Peel at least three quarters of thebonded area, even though a peel or stripping value may beindicated before this point.8.4.5 CalculationDetermine the peel strength as the aver-a
36、ge load line that accommodates the recorded curve. Recordthe load so indicated, corrected for any initial off-zero startingpoint caused by the weight of the test assembly.8.4.6 ReportingFor each series of tests, report the numberof measurements, the average, and the standard deviation of allthe test
37、 values in N/m of width lbf/ft of width.

39、n. below one of the150 mm 6 in. edges of the plywood; and bond the sheet to theplywood. Using a fine-point permanent marker, draw a linelocated at the bottom edge of the product sheet completelyacross the 150 mm 6 in. width of plywood.8.5.1.2 At least one specimen from each sample roll.8.5.2 Procedu

41、he bottom edgeof the product sheet, measure to the nearest 1 mm 0.05 in. thefurthest points of modified asphalt flow at five equally spacedlocations across the width of the specimen. For each specimen,calculate the flow across the lower edge by averaging thevalues determined at the five equally spac
42、ed locations.8.5.3 ReportReport the average of the individual speci-men averages calculated in 8.5.2.3. The average of the indi-vidual specimen averages calculated in 8.5.2.3 shall be used forcomparison with the requirement in Table 1.8.6 Side Lap Integrity (Head of Water Test)8.6.1 This test method
43、 determines the waterproof integrityof side lap seams formed according to the manufacturersinstructions or rolled as described in 8.4.2.2 at 23 6 2C 736 4F.8.6.2 Specimens:8.6.2.1 The test specimen shall consist of two pieces ofsheet, one with a salvage along the longer dimension, 200 by300 mm 8 by

45、e roll.8.6.3 Procedure:8.6.3.1 At room temperature (23 6 2C 73 6 4F), peelthe entire release paper or film off the first self-adhesive 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 c
46、oating to cover just theselvage) over the selvage positioned in a way to allow 25 mm1 in. 65 % of the salvage below to be exposed 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
47、 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 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 seala
48、nt completely around theoutside rim of the can to bond it to the membrane. As shown inFig. 1, apply the bead of caulk around all 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
49、waiting 24 h at ambient temperature for thesealant caulking to cure, fill the can to a depth of 125 mm 5in. with deionized or distilled water. Set the test assembly overa container capable of catching all the water in case there is aleak. Place the entire assembly in a refrigeration unit main-tained at 4 6 1C 40 6 2F for a period of three days.8.6.3.4
