ASTM D4637-96

1.1 This specification covers non-reinforced, fabric- or scrim-reinforced and fabric-backed vulcanized rubber sheet made from ethylene-propylene-diene terpolymer (EPDM), intended for use in single-ply roof membranes.

1.2 The test methods and property limits used to characterize these sheets are specific for each classification and are minimum values to make the product fit for its intended purpose.

1.3 In-place roof system design criteria, such as fire resistance, field seaming strength, material compatibility, and uplift resistance, among others, are factors that must be considered but are beyond the scope of this specification.

1.4 The following precautionary caveat pertains to the test methods portion only, Section 8, of this specification: 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 and health practices and determine the applicability of regulatory limitations prior to use.
