Standard Test Method for Evaluation of Water Leakage Performance of Masonry Wall Drainage Systems
|Publication Date:||1 May 2010|
This test method describes a standard procedure for determining the ability of masonry wall drainage systems to collect water that penetrates the exterior masonry wythe during rainstorms and to direct this water back to the exterior surface of the wall.
This test method is applicable to wall systems that contain an exterior masonry wythe with a drainage space on the interior face of the exterior wythe. It is not applicable to single-wythe drainage walls.
This test method is not applicable to masonry barrier walls or other masonry walls that are designed without drainage spaces behind the exterior wythe.
The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.
