A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers test procedures and conditions thatare a
3、pplicable 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 dualcantilever modes, respectively. The specific method is selectedby the ana

5、al.1.3 Membrane materials include bituminous built-uproofing, polymer-modified bitumen sheets, vulcanized rubbers,non-vulcanized polymeric sheets, and thermoplastics. Themembrane materials can be either nonreinforced or reinforced.1.4 This practice is applicable to new membrane materialsreceived fro
6、m 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 requirements of this practice.1.6 The values stated in either SI units or inc
7、h-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 non-conformancewith the standard.1.7 This standard does not purport
8、 to address all of thesafety concerns, if 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.1.8 This international standard was developed in

The tem
17、perature range can be from well-below (forexample, 80C) to somewhat (for example, 50C) aboveroom 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 memb
18、rane 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 through the use of
19、 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.5.2 Thermograv
20、imetry 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 effect of either
21、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 to low-slope
22、 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.
