ASTM WK60881

    New Practice for Use of a Low-Voltage Electronic Scanning System for Detecting and Locating Breaches in Roofing and Waterproofing Membranes

    (What is a Work Item?)

    Developed by Subcommittee: D08.22 | Committee D08 | Contact Staff Manager


    1. Scope

    1.1 This practice describes standard procedures for using an electronic scanning system to locate membrane breaches on both horizontal and vertical surfaces to locate potential leaks in exposed roofing and waterproofing membranes. 1.2 This practice addresses the need for a detailed technical description of a scanning method and procedures that are used to test and verify the integrity of membranes. 1.3 This practice is not intended to replace visual or other methods of inspection. It is to be used in conjunction with other methods of roof inspection when specified. 1.4 This practice requires that the detection and location equipment, procedures, and survey parameters used are calibrated to meet established minimum leak detection sensitivity. The detection sensitivity calibration shall be verified on a regular basis using the manufacturers procedures to assure maximum confidence in the results. 1.5 Scanning surveys can be used on membranes installed on roofs, plaza decks, pools, water features, covered reservoirs, and other roofing and waterproofing applications. 1.6 The procedures are applicable for membranes made of materials such as polyethylene, polypropylene, polyvinyl chloride, bituminous material, and other electrically insulating materials. This procedure is also useful on certain conductive membranes such as EPDM. 1.7 This practice provides a description of the scanning method and equipment for locating membrane breaches using electric conductance. This practice is intended to be used in conjunction with the manufacturers instructions for the proper operation and use of the equipment. 1.8 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.
