This European Standard sha
19、ll be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2012, and conflicting national standards shall be withdrawn at the latest by September 2012. Attention is drawn to the possibility that some of the elements of this
20、 document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13617-2:2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade
21、 Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. According to edition EN 13617-2:2004 the following fundamental changes are given: a new note at the end of the scope: Fue
22、ls other than of Explosion Group IIA are excluded from this European Standard added; informative Annex C concerning environmental aspects added. The present standard is composed of the following parts: Part 1: Safety requirements for construction and performance of metering pumps, dispensers and rem
23、ote pumping units; Part 2: Safety requirements for construction and performance of safe breaks for use on metering pumps and dispensers; Part 3: Safety requirements for construction and performance of shear valves; Part 4: Safety requirements for construction and performance of swivels for use on me
24、tering pumps and dispensers. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Gree

DIN EN 13617-2:2012-05 EN 13617-2:2012 (E) 4 1 Scope This European Standard specifies safety requ
26、irements for the construction and performance of safe breaks to be fitted to metering pumps and dispensers installed at 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 requ
27、irements apply to safe breaks at ambient temperatures from 20 C to +40 C with the possibility for an extended temperature range. It pays particular attention to electrical, mechanical and hydraulic characteristics of, and electrical apparatus incorporated within or mounted on, the safe break. This E
28、uropean Standard applies mainly to hazards related to the ignition of liquid fuels being dispensed or their vapour. This European Standard also addresses electrical and mechanical hazards. NOTE 1 This European Standard does not apply to equipment for use with liquefied petroleum gas (LPG) or liquefi
29、ed 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.
