Standard Practice for Dynamic Mechanical Analysis and Thermogravimetry of Roofing and Waterproofing Membrane Material

Fecha:
2017-05-16 /Active
Significance and Use:

5.1 Dynamic mechanical analysis provides a measure of the rheological properties of roofing and waterproofing membrane materials.

5.2 Thermogravimetry is used to characterize the thermal stability of roofing and waterproofing membrane materials under the specific temperature program and gaseous atmosphere conditions selected for the analysis.

5.3 Both dynamic mechanical analysis and thermogravimetry are used to evaluate the effect of either laboratory-simulated or in-service exposure on roofing and waterproofing membrane materials.

5.4 Both dynamic mechanical analysis and thermogravimetry can be applied to asphalt shingles. However, their application to asphalt shingles is beyond the scope of this practice, which is limited to low-slope membrane materials at this time.

5.5 This practice can be useful in the development of performance criteria for roofing and waterproofing membrane materials.

Scope:

1.1 This practice covers test procedures and conditions that are applicable when Test Methods D5023, D5024, D5026, D5279, and D5418 are used for conducting dynamic mechanical analysis of roofing and waterproofing membrane material in three-point bending, compression, tension, torsion, and dual cantilever modes, respectively. The specific method is selected by the analyst and depends on the membrane material and the operating principles of the individual instrument used for the analysis.

1.2 This practice covers test procedures and conditions that are applicable when Test Method E1131 is used for conducting thermogravimetry of roofing and waterproofing membrane material.

1.3 Membrane materials include bituminous built-up roofing, polymer-modified bitumen sheets, vulcanized rubbers, non-vulcanized polymeric sheets, and thermoplastics. The membrane materials can be either nonreinforced or reinforced.

1.4 This practice is applicable to new membrane materials received from the supplier, those exposed artificially in the laboratory or outdoors on an exposure rack, and those sampled from field installations.

1.5 This practice contains notes which are explanatory and are not part of the mandatory requirements of this practice.

1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
