ASTM D 5957 : 1998

CONTAINED IN VOL. 04.04, 2015 Gives the user with a method for testing the watertightness of waterproofing installations applied to horizontal surfaces having a slope not greater than 20 mm/m (2% slope) (1/4 in. per ft).

1.1 The purpose of this guide is to provide the user with a method for testing the watertightness of waterproofing installations applied to horizontal surfaces having a slope not greater than 1/4 in. per ft (2 percent slope) (20 mm/m).

1.2 This guide is intended for waterproofing installation on parking garages and plaza deck type applications over habitable spaces or on elevated structures, but is not intended for use on building roofing systems. Applicable waterproofing membrane installations, which may be tested using this guide, are fully adhered or bonded sheet membranes, liquid or fluid applied membranes, or loose laid sheet membranes.

1.3 The procedures presented here are not intended for use on those waterproofing installation applications that are for long-term water storage or continuously submerged environments, such as swimming pools, fountains, tank liners with hydrostatic pressure, or water storage units (storage period greater than 48 h).

1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

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.
