EN 13617-3:2012 (E) 4 Introduction The function of the shear valve is to prevent continuous liquid or vapour release in the event of impact or fire SIST EN 13617-3:2012



EN 13617-3:2012 (E) 5 1 Scope This European Standard specifies safety and environmental requirements for the construction and performance of shear valves to be fitted to metering pumps, dispensers, and/or satellite delivery systems installed at petrol filling stations and used to dispense liquid fuels into the tanks of motor vehicles, boats and light aircraft and into portable containers at flow rates up to 200 l min-1. The requirements apply to shear valves at ambient temperatures from –20 °C to +40 °C with the possibility for an extended temperature range. It pays particular attention to mechanical and hydraulic characteristics. NOTE 1 This European Standard does not apply to equipment for use with liquefied petroleum gas (LPG) or liquefied natural gas (LNG) or compressed natural gas (CNG). NOTE 2 Fuels other than of Explosion Group IIA are excluded from this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
