Standard Specification for Atactic Polypropylene (APP) Modified Bituminous Sheet Materials Using a Combination of Polyester and Glass Fiber Reinforcements

Abstract

This specification covers Grades G (granule surfaced) and S (smooth surfaced) prefabricated bituminous sheet materials reinforced with a combination of polyester fabric and glass fiber, and modified with atactic polypropylene (APP), intended for use in the fabrication of multiple ply roofing and waterproofing membranes. This specification is intended as a material specification only, and does not address issues regarding the suitability of specific roof constructions or application techniques. The specified tests and property limits used to characterize the sheet materials covered by this specification are intended to establish minimum properties. Also, in-place roof system design criteria such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, the need for field applied coatings, and others are factors beyond the scope of this material specification. The physical properties for which sheet materials shall be tested on and consequently conform to are peak load before and after heat conditioning, elongation at peak load, tear strength, low temperature flexibility, dimensional stability, compound stability, granule embedment, water absorption, moisture content, and low temperature unrolling.

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, that use atactic polypropylene (APP) 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 specific roof constructions or application techniques are beyond the scope of this specification.

1.3 The specified tests and property limits used to characterize the sheet materials covered by this specification 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, the need for field applied coatings, and others, are factors beyond the scope of this material specification.

1.4 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 nonconformance with the standard.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
