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.

• amended.
INTRODUCTION
For this third edition of IEC 60598-2-18 the main technical changes comprise the following.
For LED luminaires with bus control, multi-core cables which are suitable for the transmission
of data streams are often used. These cables are not standardized. Subclauses 18.10.4 and
18.10.5 of the previous edition allowed the use of H05 RN-F cables but this type of cable is not
suitable for the transmission of data streams.
Table 5.1 of Part 1 does not specify a special cable type for luminaires of protection class III.
Therefore 18.10.4 and 18.10.5 of the previous edition renumbered as 18.11.4 and 18.11.5 in
this edition have been adapted to allow an alternative waterproof multi-core cable that conforms
to the waterproof test of Annex D and Annex E of EN 50525-2-21:2011 or to an equivalent
regional standard.
Due to the update of Section 5 of IEC 60598-1 regarding cross-sectional areas of external and
internal cables, 18.10.3 of the previous edition is no longer relevant. Subclause 18.10.3 was
given as a less stringent requirement but in the meantime the requirements of IEC 60598-1
have become less stringent. Therefore 18.10.3 has been deleted.
