This European Standard specifies the safety, constructional and performance requirements for valve
proving systems, hereafter referred to as VPS, for gas burners and gas appliances.
It applies to all types of VPS which are used for the automatic detection of leakage in a gas burner
section having at least 2 valves designed to EN 161 and which give a signal if the leakage of one of
the valves exceeds the detection limit.
It applies to VPS with declared maximum working pressure up to and including 4 bar, for use in systems
using fuel gases of the Ist, 2nd or 3rd families.
This standard does not apply to VPS for use in explosive atmospheres.
This European Standard covers type testing only.
