ASTM C1715/C1715M-15 PDF Download

The ASTM C1715/C1715M-15 standard is a test method that evaluates the water leakage performance of masonry wall drainage systems. The test is conducted on walls to determine the system's ability to collect water that enters the exterior masonry wythe during rainstorms and to direct the water back to the exterior surface of the wall. It is specifically applicable to wall systems that have an exterior masonry wythe with a drainage zone on the interior face. The standard emphasizes the removal of a portion of the interior wall finishes to observe leakage into backup walls, but acknowledges that some areas behind obstructions may not be visible during the test.

Additionally, the standard states that it is suitable for use on mock-up walls to evaluate the performance of masonry wall drainage systems, as well as to assess the effectiveness of flashing repairs. However, it is important to note that this test method is not applicable to single-wythe drainage walls or masonry barrier walls that do not have drainage zones behind the exterior wythe.
