1、Designation:D5636/D5636M94(Reapproved 2022)Standard Test Method forLow-Temperature Unrolling of Felt or Sheet Roofing andWaterproofing Materials1This standard is issued under the fixed designation D5636/D5636M;the number immediately following the designation indicates theyear of original adoption or
2、,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 test method covers the procedure for the physicaltesting and analysis of surface
3、cracking due to low-temperatureunrolling of roofing composed of bituminous impregnated feltsand reinforced polymer-modified bituminous sheet materials.These products may employ various surfacing materials on oneside.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separ
4、ately 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 nonconformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns,if a

8、a mandrel,temperature conditioned,unrolled,and inspected for cracking.5.Significance and Use5.1 Since felts or sheet roofing or waterproofing materialsare brought to the roof in a roll and unrolled,this test methodsimulates felt or membrane behavior under actual field condi-tions during the unrollin
9、g process.5.2 This test method is designed to aid those interested inthe physical properties of roofing and waterproofing felts andsheet materials.5.3 This test method enables a researcher to measure therelative behavior of low-temperature unrolling of roofing andwaterproofing felt or sheet material
10、s under laboratory condi-tions.5.4 The data obtained from this test method will not permitservice life prediction or the ability of the material to beinstalled at the tested temperature.Unrolling capabilities areimportant during application,and the temperature at the time ofunrolling is believed to
11、affect the performance of roofing andwaterproofing membranes.However,the actual link betweenthe test data and performance is unknown and is dependent onthe materials and exposure.6.Apparatus6.1 The mandrel for the test procedure is a 680 mm3.125 in.outer diameter(Schedule 30)PVC pipe,a minimum6250 m
