This European Standard specifies safety, constructional and performance requirements of valve-proving systems, hereafter referred to as VPS, intended for use with gas burners and gas-burning appliances. It also describes the test procedures for checking compliance with these requirements and provides information necessary for the purchaser and user. This European Standard applies to all types of VPS which are used for the automatic detection of leakage in a gas burner section having at least two valves designed in accordance with EN 161 and which give a signal if the leakage of one of the valves exceeds the detection limit. This European Standard applies to VPSs with a declared maximum working pressure up to and including 500 kPa for use in systems using fuel gases of the 1 st , 2 nd or 3 rd families. This European Standard does not apply to VPSs for use in explosive atmospheres. Provisions for production control are not part of this European Standard.
