Part 2-5: Particular requirements for d.c. supplied electronic ballasts
for public transport lighting
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61347-2-5 has been prepared by subcommittee 34C: Auxiliaries
for lamps, of IEC technical committee 34: Lamps and related equipment.
This first edition of IEC 61347-2-5, together with IEC 61347-1, cancels and replaces section
four of the first edition of IEC 60924, published in 1990, and constitutes a minor revision.
This standard shall be used in conjunction with IEC 61347-1. It was established on the basis
of the first edition (2000) of that standard.
This part 2 supplements or modifies the corresponding clauses in IEC 61347-1 so as to
convert that publication into the IEC standard: Particular requirements for d.c. supplied
electronic ballasts for public transport lighting
NOTE In this standard, the following print types are used:
– Requirements proper: in roman type.
– Test specifications: in italic type.
– Explanatory matter: in smaller roman type.

lamps)
– Part 2-10: Particular requirements for electronic invertors and convertors for high-
frequency operation of cold start tubular discharge lamps (neon tubes)
– Part 2-11: Particular requirements for miscellaneous electronic circuits used with

INTRODUCTION
This first edition of IEC 61347-2-5, published in conjunction with IEC 61347-1, represents an
editorial review of section four of IEC 60924. The formatting into separately published parts
provides for ease of future amendments and revisions. Additional requirements will be added
as and when a need for them is recognized.
This standard, and the parts which make up IEC 61347-2, in referring to any of the clauses of
IEC 61347-1, specify the extent to which such a clause is applicable and the order in which
the tests are to be performed; they also include additional requirements, as necessary. All
parts which make up IEC 61347-2 are self-contained and, therefore, do not include references
to each other.
Where the requirements of any of the clauses of IEC 61347-1 are referred to in this standard
by the phrase "The requirements of clause n of IEC 61347-1 apply", this phrase is interpreted
as meaning that all requirements of the clause in question of part 1 apply, except any which
are clearly inapplicable to the specific type of lamp controlgear covered by this particular part
of IEC 61347-2.
