Scope: 1 Scope EN 13611:2019, Clause 1 is replaced by following: This document specifies the safety, design, construction and performance requirements, and testing for valve-proving systems, hereafter referred to as “VPS”, intended for use with gas burners and gas-burning appliances burning one or more gaseous fuels. This document applies to all types of VPS used for the automatic detection of leakage in a gas burner section having at least two automatic shut-off valves, and which give a signal if the leakage of one of the valves, the piping in-between the valves or of the VPS itself and its components exceeds the detection limit. This document applies to VPS for gases with a maximum inlet pressure up to and including 500 kPa. This document does not apply to VPSs for use in explosive atmospheres. This document is applicable to AC and DC supplied VPS (for VPS supplied by stand-alone battery system, battery systems for mobile applications, or VPS which are intended to be connected to DC supply networks, see Annex I).
