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 redline version of the official IEC Standard allows the user to identify the changes made to
the previous edition IEC 60598-2-22:2014+AMD1:2017 CSV. A vertical bar appears in the margin
wherever a change has been made. Additions are in green text, deletions are in strikethrough
red text.

IEC 60598-2-22 has been prepared by subcommittee 34D: Luminaires of IEC technical
committee 34: Lighting. It is an International Standard.
This fifth edition cancels and replaces the fourth edition published in 2014 and
Amendment 1:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) update of requirements for rest mode and inhibiting mode;
b) clarification of high temperature operation tests;
c) introduction of new requirements for lithium batteries;
d) introduction of new requirements for electric double layer capacitors (EDLCs);
e) clarification of resistance to heat, fire and tracking;
f) clarification of test facilities for self-contained luminaires;
g) clarification of the test method for contrast measurements of exit signs.
The text of this International Standard is based on the following documents:
Draft Report on voting
34D/1635/FDIS 34D/1642/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement,
available at www.iec.ch/members_experts/refdocs. The main document types developed by
IEC are described in greater detail at www.iec.ch/standardsdev/publications.
This Part 2-22 is to be used in conjunction with the latest edition of IEC 60598-1 and its
amendment(s). It was established on the basis of the ninth edition (2020) of that standard.
NOTE 1 When "Part 1" is mentioned in this document, it refers to IEC 60598-1.
NOTE 2 In this document, the following print type is used:
– compliance statements: in italic type.
A list of all parts in the IEC 60598 series, published under the general title Luminaires, can be
found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION to Amendment 1
The light output of LED light sources depends also on the temperature at which it is operated.
Typically the temperature is controlled by a heat sink on which it is mounted (e.g. luminaire
surface).
For this reason, the calculation of the ratio of the electrical parameter (EOF ) will be
x
introduced in the LED controlgear standards IEC 61347-2-13 and IEC 61347-2-7, as the direct
measurement of EBLF is not practicable.
In particular EOF is defined as the ratio of the current in emergency mode from constant
I
current controlgear divided by the nominal current of LED (I ):
normal mode
EOF = I / I
I emergency normal mode
Knowing that the light output of an LED light source is nearly directly proportional with the
foreward current flowing through it, it is possible to calculate the luminous flux of the luminaire
in emergency mode by using the EOF or I from constant current controlgear
.
