GB/T 30040.1-2013

This standard specifies general principles for leak detection systems used with double-walled tanks and piping, primarily for underground storage of liquids such as petroleum products or chemicals. It applies to the design, installation, and performance evaluation of these detection systems to ensure environmental protection and safety in service stations, industrial facilities, and other fluid storage contexts. The standard provides a framework for testing and compliance, covering both interstitial monitoring and external leak detection methods.
