ASTM C1715/C1715M-22 PDF Download

The ASTM C1715/C1715M-22 standard is a test method that determines the effectiveness of masonry wall drainage systems in collecting water that enters the exterior masonry wythe during rainstorms and guiding it back to the exterior surface of the wall. The scope of the standard specifies that it can be used for wall systems that have an exterior masonry wythe with a drainage zone on the interior face. However, it is not applicable to single-wythe drainage walls or masonry barrier walls that do not have drainage zones behind the exterior wythe. This standard provides a standardized procedure for evaluating the water leakage performance of masonry wall drainage systems.
