This test is meant to simulate the ability of a coating applied to a basement or other below grade masonry walls to prevent the intrusion of water through the coating caused by hydrostatic pressure from water on the outside of the structure.

1.1 This practice is for the evaluation of coatings used in below grade applications to resist the passage of water through concrete block.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 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 to determine the applicability of regulatory limitations prior to use.
