(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
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 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.3This 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.
1.4 There are no ISO standards similar or equivalent to this ASTM standard.
