1、Designation: D 5385 93 (Reapproved 2006)Standard Test Method forHydrostatic Pressure Resistance of WaterproofingMembranes1This standard is issued under the fixed designation D 5385; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, t
2、he year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method measures the hydrostatic resistance ofa waterproofing membrane under controlled laborator
3、y condi-tions. This test method is not suitable for systems that rely onconfinement of the seams by the backfill since backfill is notpart of this test method.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 This standar
4、d does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Terminology2.1 Definition:2.
5、1.1 post-formed crackfor the purposes of this testmethod, one that forms and widens behind the waterproofingmembrane after it has been applied and cured.3. Significance and Use3.1 This test method tests the hydrostatic resistance of awaterproofing membrane and can be used to compare thehydrostatic r
6、esistance of waterproofing membranes.3.2 No correlation has been established between the perfor-mance in this test method and that in the field.4. Apparatus4.1 Hydrostatic Testing Equipment, including a chamber(Fig. 1), and a clamping bracket (Fig. 2), and the gasket andfasteners to form the complet
7、ed assembly (Fig. 3).4.2 Conditioning Room, with forced air circulation to main-tain a temperature of 2 to 7C (35 to 45F) for testing sheetsystems, 18 to 24C (65 to 75F) for liquid-applied systems,and large enough to condition, prepare, and test samples.4.3 Source of Compressed Air, with pressure up
8、 to 690 kPa(100 psi) and with an air pressure controller to regulate the airin 103-kPa (15-psi) increments.4.4 Cut Off Saw, equipped with a diamond or masonryblade, to prepare precast concrete blocks for testing substrates.4.5 ClockEither a common time piece or a 1-h intervaltimer.4.6 Silicone Vacuu

Test Substrate Preparation5.1 Cut an approximately 3.2-mm (18-in.) wide kerf 44 mm(134 in.) deep lengthwise down the center of a
10、191 by 394 by51-mm (712 by 1512 by 2-in.) concrete block.5.2 Cut a kerf in at least three blocks for each system to betested, and condition the blocks at the test temperature for atleast 24 h.5.3 Condition all other materials necessary for the system tobe tested at the test temperature for at least
11、4 h.6. Sample Preparation6.1 Prime, surface condition, or otherwise prepare the sur-face of the block to receive the membrane, as recommended bythe manufacturer of the system. Permit the primer to dry orcure for the minimum time recommended by the manufacturer.6.2 For single-ply sheet samples, cut a
12、nd install the mem-brane over the prepared block, with a lap of the widthrecommended by the manufacturer perpendicular to and in thecenter of the kerf in the other side of the blocks. The edges ofthe lapped sheets should extend beyond the block edgesapproximately 6 mm (14 in.). Roll membranes intend
