Terminology3.1 DefinitionsRefer to Terminology C717 for definitionsof technical terms used in this test method.4. Summ
7、ary of Test Method4.1 This test method is conducted in two stages. In the firststage, the test membrane is subjected to hydrostatic pressurethat is increased steadily over an 8 h period until the specimenfails or the maximum pressure is achieved. In the second partof the test, three more specimens a
8、re subjected to hydrostaticpressure that is increased slowly from 50 % of the failure valueto failure in 2.5 psi increments every two to three days.5. Significance and Use5.1 This test method is used as a screening tool to determinethe hydrostatic pressure to which a liquid-applied waterproof-ing me
9、mbrane may be subjected without failing when stretchedover a crack in the substrate. This test method discriminatesbetween a membrane that is very resistant to hydrostaticpressure and one that is not. Because of the variability inherentin this test method, it is not recommended that this test method
10、be used to set a numerical standard for hydrostatic pressureresistance. No prediction of durability at lower hydrostaticpressures can be made when using the results of this testmethod.6.

20、 form a dam. Addsufficient material to yield a dry film thickness of 1.5 6 0.1 mm0.060 6 0.005 in. Check the coating thickness with a wetfilm gage. The film thickness may be built up in several coatsif specified by the manufacturer.10.1.4 For non-sag materials, stretch a rubber band aroundthe perime
