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


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.

2 Normative references

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

IEC 60809:2021, Lamps and light sources for road vehicles – Dimensional, electrical and

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


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.

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
White colour
Abbreviation Nominal CCT CIE x-coordinate boundary value
Cool white CW 5 700 K x ≤ 0,345
Neutral white NW 4 500 K 0,345 < x < 0,405
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
