Organization: ASTM
Publication Date: 1 August 2014
Status: active
Page Count: 7
scope:

This guide describes standard procedures for using electrical conductance measurement methods to locate leaks in exposed or covered waterproof membranes.

This guide addresses the need for a general technical description of the current methods and procedures that are used to test and verify the integrity of waterproof membranes.

This guide is not intended to replace visual, infrared, or other methods of inspection. It is to be used in conjunction with other methods of roof inspection when specified.

This guide recommends that the leak location equipment, procedures, and survey parameters used are calibrated to meet established minimum leak detection sensitivity. The leak detection sensitivity calibration should be verified on a regular basis according to the manufacturer's recommendations.

Leak location surveys can be used on waterproofing membranes installed in roofs, plaza decks, pools, water features, covered reservoirs and other waterproofing applications.

The procedures are applicable for membranes made of materials such as polyethylene, polypropylene, polyvinyl chloride, bituminous material, and other electrically insulating materials.

This guide provides a general description of the equipment and methods for locating membrane breaches using electric conductance. Refer to the manufacturer's instructions for the proper operation and use of the equipment described in this guide.

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.
