Scope: It applies to horizontal surfaces with a slope no greater than 2% (1/4 inch per foot).
Water Depth: The test area should be flooded to a minimum depth of 1 inch and a maximum of 4 inches at the lowest point.
Duration: The water must be maintained for a minimum of 24 hours and a maximum of 72 hours.
Curing Time: Testing should not begin until at least 24 hours after the waterproofing system installation (or 48 hours if temperatures are below 50°F/10°C). ASTM D5957-98 is the Standard Guide for Flood
Structural Review: A licensed structural engineer must verify that the building can handle the added weight of the water before testing begins. Exclusions and Warnings
Not for Roofing: This standard specifically states it is not intended for use on building roofing systems.
Temperature Limits: It is not recommended for use if freezing temperatures are expected, as ice can damage the membrane or flashings.
Leak Protocol: If a leak is detected, the water must be drained immediately, repairs made, and the test repeated after the repairs have cured.
