Standard for Nonvolumetric Precision Leak Detection Devices for Underground and Aboveground Storage Tanks and Piping for Flammable and Combustible Liquids
Scope:
1 SCOPE
1.1 This Standard provides minimum requirements for primary containment leak detection that uses
qualitative characteristics to detect leaks in the primary containment.
NOTE: Depending on the design of the tank system, and the capabilities of the leak detection devices, leaks from the
tank alone, and/or from other parts of the tank system, may be detected.
1.2 Nonvolumetric leak detection devices may be categorized, but not restricted to, one of the following
types:
A Internal Devices designed to operate within a primary containment to assess one or more
physical characteristics that would indicate a leak in the primary containment;
B External Devices designed to operate outside of a primary containment to assess physical
characteristics that would indicate a leak in the primary containment; and
C Interstitial Devices designed to operate within a secondary containment interstice to assess
physical characteristics that indicate a leak in the primary containment.
NOTE: The requirements of this Standard apply to products that may be used in static or mobile leak detection
applications.
1.3 These requirements do not cover quantitative volumetric leak detection devices.
1.4 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.
