Summary 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, 80
12、C) to somewhat (for example, 50C) above1This practice is under the jurisdiction ofASTM Committee D08 on Roofing andWaterproofing and is the direct responsibility of Subcommittee D08.20 on RoofingMembrane Systems.Current edition approved May 1, 2005.

The glass transition temperature, storagemodulus, loss modulus, and damping factor of the specimenare measured.4.2 In conducting a thermogravimetry analysis, the roofingor waterp
15、roofing membrane specimen is placed in a testchamber and subjected to a controlled, increasing temperatureprogram. The temperature range can be from about roomtemperature (for example, 20 to 40C) to well-above roomtemperature (for example, 900C), and the atmosphere of thechamber is controlled throug
16、h 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 membranematerials.5.
17、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 the effec
18、t 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 limited
19、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.
