Function Tests

The intervals for function checks of the safety valves must be
fixed by the operator of the installation under consideration of
the local requirements for pressure tanks (at least once a year
according to the recommendation of the manufacturer). The
facility operator should ensure that the function tests are
carried out regularly by an authorized person.
