Standard Test Methods for Characterizing Thermoplastic Fabrics Used in Roofing and Waterproofing
The following bibliographic material is provided to assist you with your purchasing decision:
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. The procedures appear in the following order: (1) unit mass, (2) thickness, (3) breaking load, elongation at break, and work-to-break, (4) trapezoid tearing strength, (5) puncture strength (6) static heat stability, and (7) dynamic heat stability. Sampling, test specimen preparation and conditioning, and calculations (including rupturing load and percentage change in length for puncture strength and heat stability, respectively) for the procedures are detailed. The test apparatus for the procedures are as follows: breaking load, elongation at break, and work-to-break: CRE machine; puncture strength: tensile testing machine, ring clamp attachment, and solid steel rod; static heat stability: self-supporting aluminum mounting board, oven, ruler, clips, timing device, and marking pen; dynamic heat stability: self-supporting aluminum mounting board, oven, bulldog clamps, ruler, hook weight set, timing device, and marking pen. The solid steel rod for the puncture strength test apparatus is illustrated.
