EN 13617-4:2004 (E) 4 1 Scope This document specifies safety requirements for the construction 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 particular attention to electrical, mechanical and hydraulic characteristics of swivels. This document applies mainly to hazards related to the ignition of liquid fuels being dispensed or their vapour. This document also addresses electrical and mechanical hazards of swivels. This document is not applicable to swivels for the dispensing of any compressed gas. 2 Normative references The following referenced documents are indispensable for the application of this document.

EN 13617-4:2004 (E) 5 3 Terms and definitions For the purposes of this document, the terms and definitions according to EN 13012:2001, EN 13617–1:2004 and EN 13617–2:2004 and the following apply: 3.1 swivel a device fitted between nozzle and metering pump or dispenser to allow rotational movement 3.2 single plane swivel a swivel with one plane of rotation 3.3 dual plane swivel a swivel with two planes of rotation 4 Explosion protection measures 4.1 Explosion protection measures shall be taken in accordance with EN 1127-1 and Annex B of EN 13617-1:2004. 4.2 Equipment and components used within hazardous areas shall be suitable as a minimum requirement for Explosion Group IIA and temperature class T3 as defined in EN 60079-0 and EN 13463–1.
Inside the vapour path the requirements for equipment group II, Category 1 as defined in EN 13463-1 shall apply. 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 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 13463-1:2001. 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 manufacturers' declaration and by the tests detailed in Annex A. Light alloys when used shall conform to the requirements of Clause 8 of EN 13463–1:2001. If other specifications for explosion protected equipment impose more stringent requirements then the more stringent requirement shall apply.
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 such that they allow ventilation 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 threads shall be one of the following styles: SIST EN 13617-4:2005



EN 13617-4:2004 (E) 6 Style 1: Swivels without a vapour recovery path, shall use parallel threads in accordance with EN ISO 228–1. The connection thread dimensions shall be in accordance with Table 1 Table 1 — Thread specifications Nominal connect
