Fuel vapour recovery equipment is subject to full technical inspection and undergoes periodic and ad hoc technical tests during operation.
Periodic tests are carried out at the operator’s request:
- once a year,
- once every three years for automatic monitoring systems for fuel vapour recovery equipment.
An automatic monitoring system is a system which:
- detect faults in the proper functioning of a fuel vapour recovery system and in the monitoring system itself,
- signals that faults have been detected,
- automatically stops the flow of petrol from a faulty liquid fuel dispenser if a fault is not rectified within 7 days.
Ad hoc technical tests are carried out:
- at the operator’s request to obtain authorisation for placing into service after a negative result of the previous test,
- as needed, as part of supervision over and verification of compliance with applicable laws.
