Annotation of standard text ASTM D4637/D4637M-15(2026) :

This specification covers flexible sheet made from ethylene-propylene-diene terpolymer (EPDM) intended for use in single-ply roofing membranes exposed to the weather. The rubber sheet may be non-reinforced (Type I), fabric or scrim internally reinforced (Type II), or fabric-backed (Type III) vulcanized. In-place roof system design criteria, such as fire resistance, field seaming strength, material compatibility, and uplift resistance, among others, are beyond the scope of this specification. The physical requirements for which flexible sheets shall be tested on and accordingly conform to are as follows: sheet-overall and coating over scrim or fabric thicknesses; breaking strength; tensile strength and set; dynamic and static puncture resistance; ultimate elongation and elongation at fabric break; tear resistance and strength; brittleness point; ozone resistance; behavior upon heat aging; linear dimensional change; water absorption; factory seam strength; weather resistance; and fabric adhesion.
