1.1 This standard is a performance-based practice for using the spark test to electrically locate leaks in exposed geomembranes with an insulating layer that are in intimate contact with a conductive layer. For clarity, this document uses the term leak to mean holes, punctures, tears, cuts, cracks and similar breaches over the partial or entire area of an installed geomembrane (as defined in ).
1.2 This test method can be used on exposed geomembranes installed in basins, ponds, tanks, ore and waste pads, landfill cells, landfill caps, and other containment facilities. This standard is applicable for geomembranes in direct and intimate contact with a conductive surface or with a conductive layer integrally included.
1.3 SAFETY WARNING: The electrical methods used for geomembrane leak location use high voltage, low current power supplies, resulting in the potential for electrical shock. The electrical methods used for geomembrane leak location should be attempted by only qualified and experienced personnel. Appropriate safety measures must be taken to protect the leak location operators as well as other people at the site.
This standard does not purport to address all of the safety and liability 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.
