Standard Specification for Reinforced White PIB Sheet Used in Roofing Membrane (Withdrawn 2014)

ABSTRACT
This specification covers fiber or fabric reinforced nonvulcanized white polymeric sheet made from polyisobutylene (PIB) intended for use as a single-ply roof membrane exposed to the weather. In-place roof systems design criteria such as fire resistance, field seaming strength, impact/puncture resistance, material compatibility, and uplift resistance, among others, are beyond the scope of this specification. Backed sheets shall conform to the following physical properties: thickness; breaking strength; elongation; tearing strength; low temperature bend; linear dimensional change; fabric adhesion; hydrostatic resistance; ozone resistance; and weather resistance. On the other hand, coating portions on the weather side of the sheet containing no backing shall adhere to the following physical properties: tensile strength; elongation; tear resistance; ozone resistance; and water absorption.
SCOPE
1.1 This specification covers white reinforced non-vulcanized polymeric sheet made from polyisobutylene (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.
1.2 The tests and property limits used to characterize these sheets are minimum values.
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.
The following precautionary caveat pertains to the test methods portion only, Section , 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 requirements prior to use.
WITHDRAWN RATIONALE
This specification covered white reinforced non-vulcanized polymeric sheet made from polyisobutylene (PIB) intended for use as a single-ply roof membrane exposed to the weather. The sheet shall have been reinforced with fiber or fabric.
Formerly under the jurisdiction of Committee D08 on Roofing and Waterproofing, this specification was withdrawn in July 2014 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
