Aircraft ground support equipment - Specific requirements - Part 5: Aircraft fuelling equipment
This document specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, operation and maintenance of AFE when carried out in accordance with the specifications given by the manufacturer or his authorised representative. It also takes into account some performance requirements recognised as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines, airports and fuelling companies.
This document applies to all types of aircraft fuelling equipment:
- aircraft refuellers;
- hydrant dispensers;
- defuellers;
- hydrant pit servicing vehicles;
- stationary dispensing units,
intended to service aircraft with aviation fuels and to be operated on airfields, heliports and other aircraft refuelling re-lated areas such as maintenance bases.
NOTE 1 In general, the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) is not applicable to AFE as they are not deemed to be used on public roads. However, certain requirements have been considered when developing this standard.
The use of AFE on public roads is not intended with the following exceptions:
- transportation of fuel from tank farms to refuelling areas;
- maintenance purposes with empty cargo tanks.
NOTE 2 This may include the need of local traffic derogation (see Clause 0 of EN 1915 1:2001 — negotiation).
The intended functions of AFE are:
- loading fuel from the tank farm and/or a hydrant system to the AFE;
- storage and transportation of fuel;
- fuelling from the AFE to the aircraft;
- filtration of the fuel;
- metering the fuel for a transfer of custody;
- defuelling the aircraft to the AFE;
- flushing fuel from hydrant systems;
- unloading AFE to the tank farm after defuelling of an aircraft;
- transferring fuel from one AFE to another.

ANMERKUNG 1 Im Allgemeinen ist das Europäische Übereinkommen über die internationale Beförderung gefährlicher
Güter auf der Straße (ADR) nicht auf die Luftfahrzeug-Betankungseinrichtungen anwendbar, da diese nicht für die
Benutzung auf öffentlichen Straßen konzipiert sind. Bei der Ausarbeitung der vorliegenden Norm wurden jedoch
verschiedene Anforderungen aus dem ADR berücksichtigt.
Der Betrieb von AFE auf öffentlichen Straßen ist nicht vorgesehen, mit folgenden Ausnahmen:
⎯ Transport von Kraftstoff zwischen Tanklagern und Betankungsbereichen;
⎯ Wartungszwecke mit leeren Ladungstanks.
ANMERKUNG 2 Dies kann das Erfordernis einschließen, nationale Verkehrsbeschränkungen zu beachten (siehe

EN 12312-5:2005+A1:2009 (E) 4 Introduction This document specifies health and safety requirements, as well as some functional and performance requirements for aircraft fuelling equipment (AFE) intended for use on all aircraft types commonly in service in civil air transport. The minimum essential criteria are considered to be of primary importance in providing safe, serviceable, economical and practical AFE. Deviations from the recommended criteria should occur only after careful consideration, extensive testing, risk assessment and thorough service evaluation have shown alternative methods or conditions to be satisfac-tory. This document is a Type C standard as stated in EN ISO12100-1 and EN ISO 12100-2. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indi-cated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the pro-visions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.
