ASTM C1305-08
(Test Method)Standard Test Method for Crack Bridging Ability of Liquid-Applied Waterproofing Membrane
Standard Test Method for Crack Bridging Ability of Liquid-Applied Waterproofing Membrane
SIGNIFICANCE AND USE
This test method is used to indicate a waterproofing membrane's ability to maintain its integrity while bridging a preexisting crack in the substrate at low ambient temperatures, when the membrane is least likely to be flexible.
SCOPE
1.1 This test method covers a laboratory procedure for determining the ability of a waterproofing membrane to bridge a crack in the substrate.
1.2 There are no ISO standards similar or equivalent to this ASTM standard.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.4 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.
