Standard Specification for Reinforced Non-Vulcanized Polymeric Sheet Used in Roofing Membrane

SCOPE
1.1 This specification covers reinforced non-vulcanized polymeric sheet made from chlorosulfonated polyethylene (CSM)  and poly-isobutylene (PIB) intended for use as a single-ply roof membrane exposed to the weather. The sheet shall be reinforced with fiber or fabric.
1.1.1 The polymers used in these sheets have thermoplastic characteristics at time of installation. The chlorosulfonated polyethylene will vulcanize in place under ambient conditions on a roof.
1.2 The tests and property limits used to characterize these sheets are minimum values specific for each classification.
1.2.1 In-place roof systems design criteria such as fire resistance, field seaming strength, impact/puncture resistance, material compatibility, and uplift resistance, among others, are factors that must be considered, but are beyond the scope of this specification.
1.3 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.
