ASTM D5665/D5665M-99a (R2021) PDF Download

The ASTM D5665/D5665M-99a (R2021) standard is a specification that outlines the requirements for thermoplastic fabrics used in cold-applied roofing and waterproofing applications. The standard covers fabrics made of materials such as polyester, polyester/polyamide bicomponent, or composites with fiberglass or polyester scrims.

The standard classifies the thermoplastic fabrics into seven types (Type I to Type VII). It specifies the thickness, mass, and physical properties that the fabrics must conform to. The properties of the fabrics are determined through various tests, including unit mass, thickness, breaking load and elongation, trapezoid tearing strength, and puncture strength.

It is important to note that this specification focuses on the material properties of the fabrics and does not address issues related to specific roof constructions or application techniques. The standard is intended to establish minimum properties for the fabrics and does not cover in-place system design criteria or performance attributes.
