15.1.2 Leakage containment
The standard EN 13160-7:2003 defines the following requirements for the
leakage containment:
• The design of the leakage containment (with liquid) must allow for the
indication of a minimum amount of 10 l of the leak detection fluid.
• The number of sensors in the system must correspond to the number
of recesses in the leakage containment.
• The leakage containment must be liquid-tight and impermeable to the
stored liquid. The leakage containment must not have an outlet below
the liquid level.
• No water may be able to enter the leakage containment (for example,
through rain).
- If necessary, take appropriate measures so that the function of the
product is not impaired.
• There must be no openings through the walls of the leakage space that
could impair the function of the leakage space.
• It must be possible to inspect the leakage containment for leaks.
• The primary barrier is constituted by the inner jacket or the inner tank
wall. If the leakage containment is used as a retention unit for a primary
system containing liquid, then the retention unit must be able to contain
the entire contents of the primary system.
