Anotace textu normy ASTM D5726-98(2020) :
This specification covers thermoplastic fabrics such as polyester, polyester/polyamide bicomponent, or composites with fiber glass or polyester scrims that can be used during the construction of hot-applied roofing and waterproofing. The thermoplastic fabrics are classified according to general constructions and compositions: Type I which is polyester spunbonded with resin, unneedled, Type II which is polyester spunbonded with resin, needled, Type III which is polyester mat plus fiber glass scrim and resin, and Type IV which is polyester core/polyamide sheath bicomponent spunbonded. The fabric shall be a uniform, thin, porous mat of the primary thermoplastic polymer, with or without the addition of reinforcing stranded glass or thermoplastic yarns. Chemically bonding with a water-resistant resin or thermally bonding with other thermoplastic polymers shall be permitted. Different tests shall be conducted in order to determine the following physical properties of thermoplastic fabrics: unit mass, thickness, breaking load, elongation, trapezoid tearing strength, puncture strength, appearance rating, and heat distortion stability.
Keywords:
fiberglass scrim, hot-applied roofing and waterproofing, polyester/polyamide reinforcement, polyester reinforcement, thermoplastic fabrics,, ICS Number Code 83.080.20 (Thermoplastic materials), 91.100.50 (Binders. Sealing materials)

1.1 This specification covers thermoplastic fabrics such as polyester, polyester/polyamide bicomponent, or composites with fiberglass or polyester scrims that can be used during the construction of hot-applied roofing and waterproofing. 1.2 This specification is intended as a material specification. Issues regarding the suitability of specific roof constructions or application techniques are beyond the scope of this specification. 1.3 The specified tests and property values used to characterize the respective fabrics are intended to establish minimum properties. In-place system design criteria or performance attributes are factors beyond the scope of this material specification. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 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. |
