INTERNATIONAL ELECTROTECHNICAL COMMISSION
____________
LUMINAIRES –
Part 1: General requirements and tests

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60598-1 has been prepared by subcommittee 34D: Luminaires, of
IEC technical committee 34: Lamps and related equipment.
This seventh edition cancels and replaces the sixth edition published in 2003. It constitutes a
technical revision. The major changes which may affect certification are given in Annex R.
Annex R shows where a new text has been included which contains more serious/critical
requirements requiring products to be re-tested.
The text of this standard is based on the following documents:
FDIS Report on voting
34D/889/FDIS 34D/895/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

LUMINAIRES –
Part 1: General requirements and tests

0 SECTION 0: GENERAL INTRODUCTION
0.1 Scope and object
This Part 1 of International Standard IEC 60598 specifies general requirements for luminaires,
incorporating electric light sources for operation from supply voltages up to 1 000 V. The
requirements and related tests of this standard cover: classification, marking, mechanical
construction and electrical construction.
Each section of this Part 1 is read in conjunction with this Section 0 and with other relevant
sections to which reference is made.
Each part of IEC 60598-2 details requirements for a particular type of luminaire or group of
luminaires on supply voltages not exceeding 1 000 V. These parts are published separately for
ease of revision and additional sections will be added as and when a need for them is
recognized.
Attention is drawn to the fact that this Part 1 covers all aspects of safety (electrical, thermal
and mechanical).
The presentation of photometric data for luminaires is under consideration by the International
Commission on Illumination (CIE) and is not, therefore, included in this Part 1.
Requirements are included in this Part 1 for luminaires incorporating ignitors with nominal peak
values of the voltage pulse not exceeding those of Table 11.2. The requirements apply to
luminaires with ignitors built into ballasts and to luminaires with ignitors separate from ballasts.
For luminaires with ignitors built into lamps, the requirements are under consideration.
Requirements for semi-luminaires are included in this Part 1.
In general, this Part 1 covers safety requirements for luminaires. The object of this Part 1 is to
provide a set of requirements and tests which are considered to be generally applicable to
most types of luminaires and which can be called up as required by the detail specifications of
IEC 60598-2. This Part 1 is thus not regarded as a specification in itself for any type of
luminaire, and its provisions apply only to particular types of luminaires to the extent
determined by the appropriate part of IEC 60598-2.
The parts of IEC 60598-2, in making reference to any of the sections of Part 1, specify the
extent to which that section is applicable and the order in which the tests are to be performed;
they also include additional requirements as necessary.
The order in which the sections of Part 1 are numbered has no particular significance as the
order in which their provisions apply is determined for each type of luminaire or group of
luminaires by the appropriate part of IEC 60598-2. All parts of IEC 60598-2 are self-contained
and therefore do not contain references to other parts of IEC 60598-2.

– 12 – 60598-1 © IEC:2008
Where the requirements of any of the sections of Part 1 are referred to in the parts of
IEC 60598-2 by the phrase "The requirements of section. of IEC 60598-1 apply", this phrase
is to be interpreted as meaning that all the requirements of that section of Part 1 apply except
those which are clearly inapplicable to the particular type of luminaire covered by that part of
IEC 60598-2.
For explosion proof luminaires, as covered by IEC 60079, the requirements of IEC 60598
(selecting the appropriate parts 2) are applied in addition to the requirements of IEC 60079. In
the event of any conflict between IEC 60598 and IEC 60079, the requirements of IEC 60079
take priority.
Attention is drawn to lamp performance standards which contain “information for luminaire
design”; this should be followed for proper lamp operation; however, this standard does not
require the testing of lamp performance as part of the type test approval for luminaires.
Improvements in safety to take into account the state of the art technology are incorporated in
the standards with revisions and amendments on an ongoing basis. Regional standardisation
bodies may include statements in their derived standards to cover products which have
complied with the previous document as shown by the manufacturer or standardization body.
The statements may require that for such products, the previous standard may continue to
apply to production until a defined date after which the new standard shall apply.
