DIN EN 13617-4:2012-05 EN 13617-4:2012 (E) 4 1 Scope This European Standard specifies safety requirements for the construction and performance of swivels to be fitted to delivery hose assemblies on met

24、ering 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 particular attention to electrical, mechanical and hydraulic characteristics of

25、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 liquid fuels being dispensed or their vapour. This European Standard also addresse

26、s 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 petroleum gas (LPG) or liquefied natural gas (LNG) or compressed natural gas

27、(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.

36、es 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 be Category 1 in accordance with EN 134631. The swivel shall fulfil the r

37、equirements 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 be designed and constructed according to good engineering practice and in

38、 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 of EN 13463-1:2009. Materials used in the construction shall be chemical

39、ly 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 manufacturers declaration and by the tests detailed in Annex A. Light alloys

40、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.

41、sistant 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 ventilation and evaporation of fuel even if some shrinkage occurs. The

42、y 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 threads shall be one of the following styles: Style 1 Swivels without a va

When no inner flat gasket is used the minimum thread length

45、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 15,0 mm. The inlet end shall be machined to a diameter of (35,0 0,05) m
