15、 13012:2012) has been prepared by Technical Committee CEN/TC 393 “Equipment for tanks and filling stations”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest b
16、y December 2012, and conflicting national standards shall be withdrawn at the latest by December 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all suc

Compared with the EN 13012:2001 version, the following fundamental changes have been made: a) a new note at the end of the scope was added: Fuels other than of Explosion Group IIA are excluded from this European Standard; b) an informative Ann
18、ex C concerning environmental aspects was added. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive. For relationship with EU Directives, see informative Annex ZA, which
19、is an integral part of this document. 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, Germ

BS EN 13012:2012EN 13012:2012 (E) 4 1 Scope This European Standard specifies safety and
21、environmental requirements for the construction and performance of nozzles to be fitted to metering pumps and dispensers installed at filling stations and which are used to dispense liquid fuels into the tanks of motor vehicles, boats and light aircraft and into portable containers, at flow rates up
22、 to 200 l min-1. The requirements apply to automatic nozzles dispensing flammable liquid fuels at ambient temperatures from 20 C to +40 C with the possibility for an extended temperature range. This European Standard does not apply to equipment dispensing liquefied petroleum gas nor compressed natur
23、al gas. This European Standard does not include any requirements for metering performance, such as may be specified under the Measuring Instruments Directive, nor those requirements specified under the Electromagnetic Compatibility Directive. Vapour recovery efficiency rates are not considered withi
24、n this European Standard. 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 referenc
