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.
This commented version (CMV) of the official standard IEC 60598-2-2:2023 edition 4.0
allows the user to identify the changes made to the previous IEC 60598-2-2:2011
edition 3.0. Furthermore, comments from IEC SC 34D experts are provided to explain the
reasons of the most relevant changes, or to clarify any part of the content.
A vertical bar appears in the margin wherever a change has been made. Additions are in
green text, deletions are in strikethrough red text. Experts' comments are identified by a
blue-background number. Mouse over a number to display a pop-up note with the
comment.
This publication contains the CMV and the official standard. The full list of comments is
available at the end of the CMV.

IEC 60598-2-2 has been prepared by subcommittee 34D: Luminaires, of IEC technical
committee 34:Lighting. It is an International Standard.
This fourth edition cancels and replaces the third edition published in 2011. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition (there are no major technical changes, see Annex D):
a) The requirements specific to recessed luminaries given in IEC 60598-1 are now
incorporated in this Part 2-2.
b) The requirements for air-handling luminaires given in IEC 60598-2-19 are now incorporated
in this Part 2-2.
c) The references to Part 1 have been updated.
The text of this International Standard is based on the following documents:
Draft Report on voting

LUMINAIRES –
Part 2-2: Particular requirements –
Recessed luminaires and recessed air-handling luminaires

2.1 Scope
This part of IEC 60598 specifies requirements for recessed luminaires incorporating electric
light sources for operation from supply voltages up to 1 000 V. This section does not apply to
air-handling or liquid-cooled luminaires. It also specifies requirements for recessed air-handling
luminaires for use with a ventilation duct or ventilated space (plenum).
NOTE The expressions "ventilation" and "ventilated" in this document refer to forced ventilation.
2.2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document.
