ASTM D5385-93(2000)e1

Standard Test Method for Hydrostatic Pressure Resistance of Waterproofing Membranes

SCOPE
1.1 This test method measures the hydrostatic resistance of a waterproofing membrane under controlled laboratory conditions. This test method is not suitable for systems that rely on confinement of the seams by the backfill since backfill is not part of this test method.
1.2 The primary units in this test method are inch-pounds; SI units are shown in parentheses.  
1.3 This standard does not purport to address all of the safety problems, 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.  Footnotes
  This test method is under the jurisdiction of ASTM Committee D-8 on Roofing, Waterproofing, and Bituminous Materials and is the direct responsibility of Subcommittee D08.22 on Waterproofing and Damproofing Systems.
Current edition approved May 15, 1993. Published July 1993.
