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 should occur only after careful consideration,
extensive testing, risk assessment and thorough service evaluation have shown alternative methods or
conditions to be satisfactory. Such deviations are outside the scope of this document and a
manufacturer should be able to demonstrate an equivalent level of protection.
The machinery concerned and the extent to which hazards, hazardous situations and events are
covered are indicated in the Scope of this document.
This document is a type-C standard as stated in EN ISO 12100:2010.
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises).

The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document.
When provisions of this type-C standard are different from those which are stated in type-A or type-B
standards, the provisions 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. Deviations from requirements do not fall within the presumption of conformity given by the
document.
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 added in an informative Annex E.
The use of AFE on public roads is not intended with the following exceptions:
a) transportation of fuel from tank farms to refuelling areas out of the airport premises;
b) maintenance purposes with empty cargo tanks.
NOTE This could include the need of local traffic derogation (see !EN 1915-1:2023", Introduction, f) —
negotiation).
The intended functions of AFE are:
c) loading fuel from the tank farm and/or a hydrant system to the AFE;
d) storage and transportation of fuel;
e) fuelling from the AFE to the aircraft;
f) filtration of the fuel;
g) metering the fuel for a transfer of custody;
h) defuelling the aircraft to the AFE;
i) flushing fuel from hydrant systems;
j) unloading AFE to the tank farm after defuelling of an aircraft;
k) transferring fuel from one AFE to another.
