ASTM D4811/D4811M-16

Standard Specification for Nonvulcanized (Uncured) Rubber Sheet Used as Roof Flashing

ABSTRACT
This specification covers nonvulcanized (uncured) rubber sheet made of ethylene-propylene-diene terpolymer (EPDM) or polychloroprene (CR) intended for use as watertight roof flashing exposed to the weather. 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 flashing material shall be formulated from the appropriate polymer type and other compounding ingredients, and shall be capable of being bonded to itself, to the roofing membrane, and to substrate for making watertight field splices and repairs. Property requirements for flashing before vulcanization include thickness, Green strength modulus, ultimate elongation, shelf stability, vulcanizability, tensile strength and set, dimensional stability, and weatherability. Consequently, the property requirements for flashing after vulcanization includes tensile strength and set, elongation, tear resistance, brittle point, ozone resistance, air oven heat aging, water absorption and weight change, linear dimension change, and weatherability.
SCOPE
1.1 This specification covers nonvulcanized (uncured) rubber sheet made of EPDM (ethylene-propylene-diene terpolymer) or CR (polychloroprene) intended for use as watertight roof flashing exposed to the weather.  
1.2 The tests and property limits used to characterize these flashing materials are specific for each classification and are minimum values to make the product fit for its intended purpose.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 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.  
1.5 The following precautionary caveat pertains to the test methods portion only, Section 8, of this specification:  This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address the safety concerns 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.
