EN 13760:2003 (E)4ForewordThis document EN 13760:2003 has been prepared by Technical Committee CEN/TC 286 “Liquefied Petroleum Gasequipment and accessories”, the secretariat of which is held by NSAI.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by February 2004, and conflicting national standards shall be withdrawn at the latestby February 2004.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive, see informative Annex ZA, which is an integral part of this document.Annexes A and B are normative.This document does not deal with the essential safety requirements of the Directive 97/23/EEC (PED).In the PED the nozzle is classified as a "pressure accessory". It is intended to be connected to a hose, which isclassified as "piping".¾ Article 1, 3.6 of Directive 97/23/EEC excludes equipment classified as no higher than category 1 under article9 if it is covered by Directive 94/9/EC (ATEX).¾ This document addresses the essential health and safety requirements of Directive 94/9/EC.¾ The category 1 limit is defined in Annex 2 Table 6 of the PED and is a function of the product of DN and PSwith a limit of 1 000.¾ Because the design pressure (PS) in this document is 2 500 kPa and the DN of the intended hose is less than40, the figure of 1 000 in Table 6 is not reached.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

The nozzle shall be designed and constructed according to good engineering practiceand 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 with5.2 of EN 13463-1.If the nozzle does not contain any effective ignition sources in normal operation it shall be classified as Group IIcategory 3.The design of the filling nozzle shall ensure that:a) it is suitable for use with automotive LPG as specified in EN 589;b) it is compatible with the relevant filling unit as specified in EN 12806 in accordance with annex B;
EN 13760:2003 (E)7c) entrapment of fingers and/or cold burns are not possible;d) it is not possible to open the valve in the filling nozzle if the filling nozzle is not properly locked and sealed onthe filling unit;e) it locks in the connected position;f) it is not possible to disconnect the filling nozzle from the filling unit unless the filling nozzle valve is closed;g) internal blocking due to freezing does not occur;h) it is tolerant to the effect of dirt;i) it will withstand a torque of 150 % of the mounting torque specified by the manufacturer without damage;j) k) the materials in contact with LPG are LPG-compatible;l) the external surfaces of the filling nozzle are corrosion resistant or protected against corrosion and are made ofmaterials that do not cause sparks when dropped on a surface;m) the minimum lifetime is 100 000 cycles;n) the maximum design temperature is 65 °C and the minimum design temperature is –20 °C. For extreme coldoperating conditions, a minimum design temperature of –40 °C shall be applied;o) the design pressure is 2 500 kPa;p) a locking mechanism is incorporated;q) the nozzle is provided with a means to securely attach it to the delivery hose.4.2 Service gasketThe service gasket between the filling nozzle and the filling unit, if required, shall be fitted in the nozzle.Changing the service gasket shall not result in any LPG release.The minimum lifetime of the service gasket shall be 20 000 cycles.4.3 Specific requirements4.3.1 Light duty vehicle filling nozzleThe release of LPG during disconnection shall be less than 1 cm3 liquid.The flow-rate through the filling nozzle, at a pressure difference of 70 kPa, shall be at least 60 l/min.The maximum weight of the filling nozzle shall be 2 kg (including swivel, if fitted).The external diameter of the filling nozzle shall not exceed 54 mm
