1.1 This test method covers the evaluation of the dynamic puncture energy that roofing membrane specimens can withstand, without allowing the passage of water, when subjected to impact from a rigid object having a sharp edge.
1.2 This laboratory test can be conducted at any desired temperature using membrane specimens 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; however, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
