AMENDMENT 2
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 document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 2 to IEC 60810:2017 has been prepared by subcommittee 34A: Electric light
sources, of IEC technical committee 34: Lighting.
The text of this Amendment is based on the following documents:
Draft Report on voting
34A/2272/FDIS 34A/2277/RVD
Full information on the voting for its approval can be found in the report on voting indicated in

described in greater detail at www.iec.ch/standardsdev/publications/.
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

2 Normative references
Replace the existing reference to IEC 60809:2014 with the following new reference:

luminous requirements
3 Terms and definitions

Replace, in the note to entry, "IEC 60809:2014" with "IEC 60809:2021".
6 Requirements and test conditions for discharge lamps
Add, at the end of Subclause 6.8, the following new Subclause 6.9:
6.9 White colour groups
The discharge lamp shall be marked with the applicable colour group name or its abbreviation
or its nominal CCT value as defined in Table 17. No marking is required for discharge lamps of
the white colour group "Neutral white".
NOTE "Neutral white" is considered as the default white colour group for discharge lamps (e.g. in UN Resolution
R.E.5).
These three white colour groups are defined with a nominal correlated colour temperature (CCT).
The white colour space, which is subdivided into these colour groups, is defined in UN
Regulation No. 48 and in IEC 60809:2021, 4.4.

– 4 – IEC 60810:2017/AMD2:2022

The three colour groups are separated by their x-coordinate value from the CIE x,y chromaticity
coordinates according to CIE 015, as shown in Table 17 and Figure 14:
Table 17 – Three white colour groups, their abbreviation, nominal CCT
and CIE x-coordinate boundary value for discharge lamps

Warm white WW 3 500 K x ≥ 0,405

Figure 14 – Three white colour groups for discharge lamps
For the purpose of measuring the colour group of a discharge lamp, the CIE colour coordinates
(x,y) shall be tested under the following conditions:
• Prior to the test, the discharge lamp shall be aged for 10 on/off switching cycles as specified
