Are European suction systems required to have a line test as part of release detection?

• A. Always required
• B. Sometimes required
• C. Never required
• D. No line test is required

Answer: (D)

In European practice, release detection for underground systems is built around continuous monitoring methods that cover both the tank and the connected piping. A separate line test, done as a routine part of release detection for suction lines, isn’t generally mandated. Instead, leak detection relies on measures like interstitial monitoring, automatic tank gauging with leak thresholds, inventory reconciliation, and, where applicable, line leak detectors. Because of this approach, a dedicated line test isn’t required as part of standard release detection for suction systems. Exceptions can exist for commissioning or after major work, but as a routine requirement, it’s not imposed.
