Summary of Test
ASTM D5385 is a testing standard that measures the hydrostatic resistance of a waterproofing membrane under controlled laboratory conditions. The results of this testing can be used to compare the hydrostatic resistance of waterproofing membranes.
A hydrostatic testing machine with a chamber, a clamping bracket, and a gasket is required to run ASTM D5385. The testing area should also have a source of compressed air with pressure up to 100 psi (690kPa) as well as a clock or a 1-hour interval timer to add air pressure each hour (or time specified).
Prior to conducting ASTM D5385, it is important to read the entire specification in the relevant ASTM publication.
Recommended Equipment
Testing Procedure
- Prepare the specimens as described in the standard.
- Load the sample following the steps under Section 7.1.
- Start the test when the pressure chamber is filled.
- Monitor the assembly for leaks for 30 minutes and at times specified.
- End test when a pressure drop is detected.
- After test completion, evacuate the liquid from the chamber.
