Full Name

ASTM C1601 – Standard Test Method for Field Determination of Water Penetration of Masonry Wall Surfaces


This test method covers the field determination of water penetration of a masonry wall surface under specific water flow rate and air pressure conditions.

This test is intended for use on any masonry wall surface that can be properly instrumented and tested within the requirements of this standard.

This test method is not identical to and the results are not the same as laboratory standard Test Method E514/E514M. Test Method E514/E514M measures through-wall water penetration, whereas this test method only measures surface water penetration.
