This specification covers prefabricated bituminous sheet materials reinforced with a combination of polyester fabric and glass fiber, with or without granules, modified by styrene butadiene styrene (SBS) thermoplastic elastomer, and are intended for use in the fabrication of multiple ply roofing and waterproofing membranes. This specification is intended as a material specification only. Hence, issues regarding the suitability of the specific roof constructions or application techniques are beyond this scope. Also not addressed here are in-place roof system design criteria such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, and others. Materials shall conform to specified values of the following dimensional and physical properties: total and bottom coating thickness; net mass per unit area; peak load before and after heat conditioning; elongation at peak load; ultimate elongation; tear strength; low temperature flexibility; dimensional stability; compound stability; and granule embedment.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers prefabricated modified bituminous sheet materials reinforced with a combination of polyester fabric and glass fiber, with or without granules, which use styrene butadiene styrene (SBS) thermoplastic elastomer as the primary modifier and are intended for use in the fabrication of multiple ply roofing and waterproofing membranes.

1.2 This specification is intended as a material specification only. Issues regarding the suitability of the specific roof constructions or application techniques are beyond this scope.

1.3 The specified tests and property limits used to characterize the sheet materials are intended to establish minimum properties. In-place roof system design criteria such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, and others, are factors beyond the scope of this material specification.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
