(Test Method)Standard Test Method for Water Penetration and Leakage Through Masonry
Standard Test Method for Water Penetration and Leakage Through Masonry
SCOPE
1.1 This laboratory test method provides a procedure for determining the resistance to water penetration and leakage through unit masonry subjected to wind-driven rain.
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. For a specific hazard statement see Section .
