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);
— consumers (in case of machinery intended for use by consumers).

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 1915-1:2013, Introduction, f) —

negotiation).
---------------------- Page: 8 ----------------------
SIST EN 12312-5:2021
EN 12312-5:2021 (E)
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.

1 Scope

This document specifies the technical requirements to minimize the hazards listed in Clause 4 which

can arise during the commissioning, operation and maintenance of AFE when used as intended,

including misuse reasonably foreseeable by the manufacturer, when carried out in accordance with the

specifications given by the manufacturer or his authorized representative. It also takes into account

some performance requirements recognized 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:
a) aircraft refuellers,
b) hydrant dispensers,
c) defuellers,
d) hydrant pit servicing vehicles,
e) pit cleaner vehicles, and
f) stationary dispensing units

intended to service aircraft with aviation fuels and to be operated on airfields, heliports and other

aircraft refuelling related areas such as maintenance bases.
This document does not apply to:

g) AFE whose only power source for aircraft refuelling is directly applied manual effort,

h) hydrant systems, tank farms, pipework and underground tanks,

i) specific hazards due to the operation of the AFE in a potentially explosive atmosphere, and

j) built-in fire extinguisher systems.
No extra requirements on noise and vibration are provided other than those in
EN 1915-3:2004+A1:2009 and EN 1915-4:2004+A1:2009.

NOTE EN 1915-3:2004+A1:2009 and EN 1915-4:2004+A1:2009 provide the general GSE vibration and noise

requirements.

This document does not deal with hazards in respect to a standard automotive chassis and from other

vehicles on the apron.

This document is not applicable to AFE which are manufactured before the date of publication of this

document by CEN.
This part of the EN 12312 series when used in conjunction with EN 1915-1:2013,

EN 1915-2:2001+A1:2009, EN 1915-3:2004+A1:2009 (for vehicles) and EN 1915-4:2004+A1:2009
