(Test Method)Standard Test Method for Hydrostatic Pressure Resistance of a Liquid-Applied Waterproofing Membrane
Standard Test Method for Hydrostatic Pressure Resistance of a Liquid-Applied Waterproofing Membrane
SCOPE
1.1 This test method describes a laboratory procedure for determining the resistance of a waterproofing membrane to hydrostatic pressure.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units 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 determine the applicability of regulatory limitations prior to use.

9. Conditioning/Mixing
9.1 Store all materials to be tested at standard conditions of
23 6 2°C (73.4 6 3.6°F) and 50 6 5 % relative humidity for
at least 24 h before any test specimens are prepared.
9.2 Follow the manufacturer’s instructions for mixing and
preparing membrane materials for testing.
9.3 When a primer is required by the membrane manufac-
turer, use the primer as instructed by the membrane manufac-
turer.
10. Procedure
10.1 Application of the Membrane to the Test Substrate:

10.1.2 Measure the thickness of each block to the nearest
0.025 mm (0.001 in.), using vernier calipers. Record this value.
10.1.3 For self-leveling membrane materials, lay the bound
blocks on a sand bed and level them.Apply 50 mm (1 in.) wide
masking tape around the perimeter of the joined test substrates
so that approximately half of the width of the tape protrudes
above the test surface on all four sides to form a dam. Add
