GB/T 30040.4-2013 Leak detection systems—Part 4:Liquid and/or vapour sensor systems for use in leakage containments or interstitial spaces

Scope

This part of GB/T 30040 specifies the overview of the Class III leak detection system for double-layered systems storing liquids that pollute water, or for single-layered systems with anti-leakage facilities; double-layered gaps, anti-leakage facilities, liquid sensors, vapor sensors, leak display devices, type testing of liquid sensors, type testing of liquid identification sensors, type testing of vapor sensors, and type testing of immersion-type vapor sensors.
This part applies to the Class III leak detection system for double-layered systems storing liquids that pollute water, or for single-layered systems with anti-leakage facilities, but does not apply to leak monitoring systems that use sensors that cannot be reused.
