Standard Guide for Low Slope Insulated Roof Membrane Assembly Performance
A roof assembly must work as a system. Any component of the roof assembly demonstrating an inherent weakness or inability to perform will diminish the roof system performance and service life expected. This guide lists minimum performance attributes required of low slope roof assemblies. Products not previously used as roof membrane materials require additional tests beyond the scope of this document. This guide is not intended for use on in-service roofing materials. Roof membranes and other components should conform to ASTM product standards, if available.
1.1 This guide lists test methods intended to establish a minimum level of performance for insulated roof membrane assemblies, and lists pertinent design guidelines and installation methods in a unified manner. Material tests and evaluations are included with and without roof insulation.
1.2 It is not possible to establish a precise correlation between laboratory tests on roof assemblies and natural weathering due to variations in geographical climate, design, material and installation.
1.3 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.
