This specification covered in-situ applied, single-pack, moisture-triggered, aliphatic polyurethanes intended to form an elastomeric single-ply membrane, once cured. The cured membrane may or may not contain a reinforcing material.
Formerly under the jurisdiction of Committee D08 on Roofing and Waterproofing, this specification was withdrawn in August 2013. This standard is being withdrawn without replacement because the language in the scope together with the title presented a confusing package to the user. The title promised a specification for a roofing membrane while the scope presented a specification for the material used to make the membrane.
1.1 This specification covers in-situ applied, single-pack, moisture-triggered, aliphatic polyurethanes intended to form an elastomeric single-ply membrane, once cured. The cured membrane may or may not contain a reinforcing material.
1.2 Single-pack, moisture-triggered, aliphatic polyurethanes are characterized by their ability to use moisture to trigger the curing process only.
1.3 The tests and property limits used to characterize the liquid material and cured membrane are values intended to ensure minimum quality. In-place roof system design criteria such as fire resistance, material compatibility, and uplift resistance, among others, are factors that shall be considered but are 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 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 limitations prior to use.
