Over deze norm
1.1 This test method covers evaluation of the maximum static puncture load that roofing membrane samples can withstand without allowing the passage of water.
1.2 This laboratory test is conducted at any desired temperature using sheet membrane samples manufactured in a factory or prepared in a laboratory.
1.3 Roof membrane specimens to which the test method is applicable include bituminous built up, polymer-modified bitumens, vulcanized rubbers, non-vulcanized polymeric, and thermoplastic materials.
1.3.1 The applicability of this test method to these membrane specimens includes their use in vegetative roof systems.
1.4 This test method is not applicable to aggregate-surfaced membrane specimens, but it is applicable to specimens having factory-applied granules.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.6 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.
