Historical (view previous versions of standard)
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.
