This test method is suitable for use on walls to determine the ability of masonry wall drainage systems to collect water penetrating the exterior wythe and to direct this water back to the exterior surface of the exterior wythe. Removal of a portion of the interior wall finishes is desirable to observe leakage into backup walls. Even with removal of interior finishes, in many cases it is not practical to observe surfaces behind spandrel beams, columns, or other obstructions. Potential areas where leakage may occur but that are not visible during the test shall be considered when interpreting the results of the test and shall be recorded in the report.
This test method is suitable for use on mock-up walls to determine the performance of masonry wall drainage systems.
This test method is suitable for evaluating the effectiveness of flashing repairs.View Less
1.1 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.
1.2 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.
1.3 This test method is not applicable to masonry barrier walls or other masonry walls that are designed without drainage spaces behind the exterior wythe.
1.4 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.
1.5 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.
