FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62282-4-101 has been prepared by IEC technical committee 105:

The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

INTRODUCTION
IEC 62282-4 deals with categories such as safety, performance and interchangeability of fuel
cell power systems for propulsion other than road vehicles and auxiliary power units (APU).
Among the categories mentioned above, this standard, IEC 62282-4-101, focuses on safety of
industrial electric trucks with fuel cell power systems because such an application is urgently
demanded in the world. The future standards in the Part 4 series will deal with other
applications related to onboard vehicles other than road vehicles and auxiliary power units
(APU).

FUEL CELL TECHNOLOGIES –
Part 4-101: Fuel cell power systems for propulsion other
than road vehicles and auxiliary power units (APU) –
Safety of electrically powered industrial trucks

1 Scope
1.1 This part of IEC 62282 covers safety requirements for fuel cell power systems intended
to be used in electrically powered industrial trucks.
1.2 This standard is limited to electrically powered industrial trucks and is applicable to
material-handling equipment, e.g. forklifts.
1.3 This standard applies to gaseous hydrogen-fuelled fuel cell power systems and direct
methanol fuel cell power systems for electrically powered industrial trucks.
1.4 The following fuels are considered within the scope of this standard:
– gaseous hydrogen
– methanol.
1.5 This standard covers the fuel cell power system as defined in 3.8 and Figure 1.
1.6 This standard applies to d.c. type fuel cell power systems, with a rated output voltage
not exceeding 150 V d.c. for indoor and outdoor use.
1.7 This standard covers fuel cell power systems whose fuel source container is
permanently attached to either the industrial truck or the fuel cell power system.
1.8 The following are not included in the scope of this standard:
– detachable type fuel source containers;
– hybrid trucks that include an internal combustion engine;
– reformer-equipped fuel cell power systems;
