The function of the leak detection system must be checked at
appropriate intervals, at least twice per year.
The test must be performed in such a way as to verify the correct
function of the leak detection system in terms of the interaction of all
components when the sensors are wetted.
Probes that have been attacked by the liquid to be detected must be
replaced. It is the responsibility of the owner/operator to choose the
type of inspection and the intervals during the period mentioned.
