3、1.1 This practice covers test procedures and conditions thatare applicable when Test Methods D5023, D5024, D5026,D5279, and D5418 are used for conducting dynamic mechani-cal analysis of roofing and waterproofing membrane material inthree-point bending, compression, tension, torsion, and dualcantilev
4、er modes, respectively. The specific method is selectedby the analyst and depends on the membrane material and theoperating principles of the individual instrument used for theanalysis.1.2 This practice covers test procedures and conditions thatare applicable when Test Method E1131 is used for condu
5、ctingthermogravimetry of roofing and waterproofing membranematerial.1.3 Membrane materials include bituminous built-up roof-ing, polymer-modified bitumen sheets, vulcanized rubbers,non-vulcanized polymeric sheets, and thermoplastics. Themembrane materials can be either nonreinforced or reinforced.1.
6、4 This practice is applicable to new membrane materialsreceived from the supplier, those exposed artificially in thelaboratory or outdoors on an exposure rack, and those sampledfrom field installations.1.5 This practice contains notes which are explanatory andare not part of the mandatory requiremen
7、ts of this practice.1.6 The values stated in either SI units or inch-pound unitsare to be regarded separately 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
8、non-conformancewith the standard.1.7 This standard does not purport to address all of thesafety concerns, if any, associated with its use.

12、mary of Practice4.1 In conducting a dynamic mechanical analysis, the roof-ing or waterproofing membrane specimen is placed in a testchamber and subjected to a controlled, increasing temperatureprogram. The temperature range can be from well-below (forexample, 80C) to somewhat (for example, 50C) abov
13、eroom temperature. The glass transition temperature, storagemodulus, loss modulus, and damping factor of the specimenare measured.4.2 In conducting a thermogravimetry analysis, the roofingor waterproofing membrane specimen is placed in a test1This practice is under the jurisdiction ofASTM Committee

17、ed through the use of inert gas such asnitrogen or reactive gas such as air. The percent mass loss ofthe specimen is determined as a function of temperature.5. Significance and Use5.1 Dynamic mechanical analysis provides a measure of therheological properties of roofing and waterproofing membranemat
18、erials.5.2 Thermogravimetry is used to characterize the thermalstability of roofing and waterproofing membrane materialsunder the specific temperature program and gaseous atmo-sphere conditions selected for the analysis.5.3 Both dynamic mechanical analysis and thermogravim-etry are used to evaluate
19、the effect of either laboratory-simulated or in-service exposure on roofing and waterproofingmembrane materials.5.4 Both dynamic mechanical analysis and thermogravim-etry can be applied to asphalt shingles. However, their appli-cation to asphalt shingles is beyond the scope of this practice,which is
20、 limited to low-slope membrane materials at this time.5.5 This practice can be useful in the development ofperformance criteria for roofing and waterproofing membranematerials.DYNAMIC MECHANICAL ANALYSIS6. Test Procedure6.1 Select the specific test method (that is, Test MethodD5023, D5024, D5026, D5
