(Specification)Standard Specification for Fiberglass Reinforced Styrene-Butadiene-Styrene (SBS) Modified Bituminous Sheets with a Factory Applied Metal Surface
Standard Specification for Fiberglass Reinforced Styrene-Butadiene-Styrene (SBS) Modified Bituminous Sheets with a Factory Applied Metal Surface
ABSTRACT
This specification covers fiberglass reinforced bituminous sheet materials modified by styrene-butadiene-styrene (SBS) thermoplastic elastomer, and are surfaced with a factory applied continuous metal foil. These materials are intended for use in the fabrication of multiple ply roofing and waterproofing membranes and flashings. This is intended as a material specification only, and does not address specific roof constructions or application techniques. The specified tests and property limits are intended to establish minimum properties. 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 specification. The properties for which the materials shall be tested on and consequently conform to are thickness, net mass per unit, back surface coating thickness, peak load value, elongation at peak load, ultimate elongation, tensile-tear strength, low-temperature flexibility, dimensional stability, compound stability, cyclic thermal shock, water absorption, and moisture content.
SCOPE
1.1 This specification covers fiberglass reinforced modified bituminous sheet materials that use styrene-butadiene-styrene (SBS) thermoplastic elastomer as the primary modifier and are surfaced with a factory applied continuous metal foil. These materials are intended for use in the fabrication of multiple ply roofing and waterproofing membranes and flashings.
1.2 This specification is intended as a material specification only. Questions regarding the suitability of the specific roof constructions or application techniques are beyond the scope of this specification.
1.3 The specified tests and property limits 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 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 non-conformance with the standard.
1.5 The following precautionary statement pertains to the test method 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, 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.
