Standard for Leak Detection Devices (Volumetric Type) for Underground Storage Tanks for Flammable Liquids and Combustible Liquids

1.1 This Standard provides minimum requirements for primary containment leak detection that uses quantitative assessment of physical characteristics to detect leaks in the primary containment.

1.2 These requirements do not cover qualitative nonvolumetric leak detection devices.

1.3 The requirements of this Standard apply to newly-manufactured products. The requirements of this Standard do not apply to installation and monitoring procedures.

NOTE: The identifier “leak detection device” used throughout this document applies to the sensor, plus any cables, connected equipment, software, and display necessary to detect and declare a leak. Since the elements of a particular product may range from all of these items, to a sensor with an integrated display alone, the requirements for marking permit the product elements to be marked “leak detection device” or “leak detection equipment” as appropriate.
