ASTM C1601-22a PDF Download

ASTM C1601-22a is a standard test method that aims to determine the water penetration of masonry wall surfaces in the field. The test is conducted by subjecting the masonry wall surface to specific water flow rate and air pressure conditions. This test can be applied to any masonry wall surface that can be appropriately instrumented and tested according to the requirements of the standard.

It is important to note that this test method should not be confused with laboratory standard Test Method E514/E514M, as the results obtained from the field test are not the same as through-wall water penetration measured by Test Method E514/E514M. ASTM C1601-22a exclusively measures surface water penetration rather than water penetration across the entire wall structure.
