1.1 This test method covers the determination of water migration resistance of roof membranes including built-up roof membranes, modified bitumen, and single ply roof membranes. The procedures were developed to determine the potential for leakage of water through the roof membranes resulting from a standing head of water and when pressurized with air from the underside.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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 limitations prior to use.


5.1 This test method provides a means of evaluating roof membranes, seams, and laps for resistance to water migration from standing water on the roof. This test method evaluates roof membranes when first applied and also after simulated deterioration caused by the ultraviolet energy of the sun.
