This European Standard shall be given the status of
15、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of an identical text or by endorsement, at the latest by September 2012, and conflicting national standards shall be withdrawn at the latest by September 2012.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 document may be the subje
16、ct of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13617-4:2004. According to edition EN 13617-4:2004 the following fundamental changes are given: a new note at the end of the scope: Fuels other than of Exp

BS EN 13617-4:2012EN 13617-4:2012 (E) 4 1 Scope This European Standard specifies safety requirements for the construct
22、ion and performance of swivels to be fitted to delivery hose assemblies on 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. It pays pa
23、rticular attention to electrical, mechanical and hydraulic characteristics of swivels. The requirements apply to swivels at ambient temperatures from 20 C to +40 C with the possibility for an extended temperature range. This European Standard applies mainly to hazards related to the ignition of liqu
24、id fuels being dispensed or their vapour. This European Standard also addresses electrical and mechanical hazards of swivels. This European Standard is not applicable to swivels for the dispensing of any compressed gas. NOTE 1 This European Standard does not apply to equipment for use with liquefied
25、 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 indis

34、 rotation 4 Explosion protection measures 4.1 Explosion protection measures shall be taken in accordance with EN 1127-1 and Annex B of EN 13617-1:2012. 4.2 The swivel shall be explosion protected and shall be Category 2 in accordance with EN 134631. The vapour path of a vapour recovery swivel shall
35、be Category 1 in accordance with EN 134631. The swivel shall fulfil the requirements for temperature Class T3 and Group IIA to EN 60079-0 or EN 134631. 5 Construction 5.1 General All electrical and non-electrical equipment and components, intended for use in potentially explosive atmospheres, shall
36、be designed and constructed according to good engineering practice and in conformity with the required categories for Group II equipment to ensure avoidance of any ignition source. To classify the category of the equipment it shall be subjected to an ignition hazard assessment in accordance with 5.2
37、 of EN 13463-1:2009. Materials used in the construction shall be chemically and dimensionally stable under known service conditions. Materials likely to come into contact with fuels in both liquid and vapour phases shall be resistant to attack by these fuels. Conformity shall be demonstrated by manu
38、facturers declaration and by the tests detailed in Annex A. Light alloys when used shall conform to the requirements of 6.4.4.2 of EN 134631:2009. If other specifications for explosion protected equipment impose more stringent requirements then the more stringent requirement shall apply. BS EN 13617
39、-4:2012EN 13617-4:2012 (E) 6 All components shall be of corrosion resistant material or shall be provided with a corrosion resistant protective coating. Outside surfaces likely to be handled shall be free of sharp edges. If protective covers are fitted they shall be constructed so that they allow ve
40、ntilation and evaporation of fuel even if some shrinkage occurs. They shall not affect the performance of the swivels. The sealing surfaces of the connection threads shall be designed such that they are suitable for use with an enclosed O-ring or flat gasket. 5.2 Connection threads Connection thread

43、gasket. When no inner flat gasket is used the minimum thread length depends on the tightness requirements of the threaded connection. Style 2: Swivels with a vapour recovery path shall use M 34 x 1,5 male outlet threads according to ISO 261 and ISO 965-2. The total thread length shall be maximum 15,
