1、Designation: D 5636 94 (Reapproved 2005)Standard Test Method forLow Temperature Unrolling of Felt or Sheet Roofing andWaterproofing Materials1This standard is issued under the fixed designation D 5636; the number immediately following the designation indicates the year oforiginal adoption or, in the
2、 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 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 SI units are to be regarded as thestandard. The values give

6、ing or waterproofing material roll istemperature conditioned. Specimens are then taken from theroll, wrapped around 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 r

8、searcher to measure therelative behavior of low temperature unrolling of roofing andwaterproofing felt or sheet materials 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 temper
9、ature. Unrolling capabilities areimportant during application, and the temperature at the time ofunrolling is believed to affect the performance of roofing andwaterproofing membranes. However, the actual link betweenthe test data and performance is unknown and is dependent onthe materials and exposu
10、re.6. Apparatus6.1 The mandrel for the test procedure is a 680 mm (3.125in.) outer diameter (Schedule 30) PVC pipe, a minimum 6250mm (10.0 in.) in length).7. Test Method7.1 Unrolling at Low TemperaturesThis test method de-termines the temperature at which no cracking is observed inthe felt or sheet
11、roofing or waterproofing materials afterunrolling at the test temperature from a 680 mm (3.125 in.)diameter mandrel.7.2 Sampling:7.2.1 The specimens are to be taken from a roll of roofing orwaterproofing materials conditioned at 23 6 3C(73.6 6 3.4F) and 50 6 5 % relative humidity for 24 h. Nospecime
12、ns are to be taken closer than 61.22 m (4 ft.) from theleading edge or closer than 6150 mm (6 in.) from the side ofthe roll.1This test method is under the jurisdiction ofASTM Committee D08 on Roofingand Waterproofing and is the direct responsibility of Subcommittee D08.20 onRoofing Membrane Systems.

15、250 mm (63 mm) 10 in.6 (18 in.) wide by 6450 mm (63 mm) 18 in. (618 in.) long.8. Procedure8.1 Secure the specimen to the mandrel, weather sideagainst mandrel, with polyethylene tape. Wrap the temperatureconditioned specimen evenly and firmly around the mandrel.Secure the specimen to the mandrel, wra
16、pping sufficiently withclear plastic wrap, and maintain the specimen on the mandrelat 23 6 3C (73 6 3.4F) and 50 6 5 % relative humidity for24 h.8.2 Place the specimen assembly in a refrigeration unit at atemperature where the felt or sheet is presumed to be capableof passing. If this information is
17、 not available, make apreliminary screening test at 0 6 1C (32 6 2F). Maintain thetemperature in the refrigeration unit at desired temperature0.5C (61F) for a minimum of 2 h. Change the temperatureintervals in preceding tests at 62C (64F). Allow therefrigerated unit and mandrel to equilibrate before
18、 proceedingwith subsequent testing.8.3 Remove the specimen assembly from the refrigerationunit. Remove the plastic wrap. Carefully and evenly clamp theexposed end of the specimen to a clip board. Unroll thespecimen onto a horizontal surface, keeping the material flatagainst the surface. Time allowan
19、ce for removal from refrig-erated unit to unrolling is 30 s, and time allowance of unrollingis between 4 and 6 s. Inspect for signs of cracking. Record thelocation and length of any cracks. Consider any visible surfaceruptures as a failure.8.4 Repeat the procedure until the lowest temperature atwhic
20、h none of the specimens show cracking is achieved.Allowthe refrigeration unit to equilibrate before testing subsequentspecimens at different temperatures.9. Report9.1 Report complete specimen identification and the lowesttemperature where cracking is not evident to the unaided eye.Tested specimens m
21、ay not be reused for successive testing atlower or higher temperatures. For the purposes of this testmethod, any surface crack is considered a failure at the testedtemperature where the crack appears.10.
