Standard Test Methods for Characterizing Thermoplastic Fabrics Used in Roofing and Waterproofing

Fecha:
2016-12-27 /Active
Scope:

1.1 These test methods cover the procedures for characterizing thermoplastic fabrics (for example polyester, polyamide, polypropylene, and so forth) used in prefabricated roofing and waterproofing membranes.

1.2 Procedures appear in the following order:

 

Section

Unit Mass

3

Thickness

4

Breaking Load, Elongation and Work-to-Break

5

Trapezoid Tearing Strength

6

Puncture Strength

7

Static Heat Stability

8

Dynamic Heat Stability

9


1.3 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.

1.4 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.
