Roof flood testing astm.

Manufacturers should specify a minimum time period for materials to cure prior to performing flood test however no testing should be performed during the first 24 h following installation of system materials 48 h min if materials are installed at a time when ambient temperatures are below 10 c 50 f. It is commonly referenced as the standard for flood testing roof systems. These systems are assembled in the uppermost part of building structures to provide protection and insulation from external elements such as rain sunlight and heat. This astm testing procedure utilizes a calibrated spray rack with specific water pressures nozzles and distances to wet a wall with water at the rate of five gallons per square foot per hour.

However astm d5957 specifically states the standard is not intended for use on building roofs astm d5957 references a maximum water depth of 100 mm 4 in. Standard guide for flood testing horizontal waterproofing installations. Astm d5957 98 2013 illustrates a method for testing the water tightness of waterproofing installations applied to horizontal surfaces having a slope of no greater than 20 mm m 2 slope 1 4 per ft.
