Norme ASTM C1601-09
1.1 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.
1.2 This test method is not identical to and the results are not directly comparable with the laboratory standard Test Method E 514
1.3 Surface penetration, as determined by this test method, is defined as the amount of water passing through the wall surface exposed to testing per unit time per unit area. This property is not directly comparable to overall water penetration and leakage, which are typically defined as the amount of water travelling completely through a masonry system.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard may involve hazardous materials, operations, or equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
