ASSESSMENT OF LIGHTING EQUIPMENT RELATED

AMENDMENT 1
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 1 to IEC 62493:2015 has been prepared by IEC technical committee 34: Lighting.
The text of this Amendment is based on the following documents:

INTRODUCTION
Replace the second paragraph of the introduction with the following new paragraph:
This standard is designed to assess, by measurements and/or calculations, electromagnetic
(EM) fields and their potential effect on the human body by reference to exposure levels of the
general public given by ICNIRP 2020 [1] , ICNIRP 2010 [2], IEEE C95.1:2005 [3] and IEEE
C95.6:2002 [4]. The exposure levels with which to comply are basic restrictions (both ICNIRP-
and IEEE-based).
3 Terms, definitions, physical quantities, units and abbreviations
3.1.14
intentional radiator
Add the following Note to entry to terminological entry 3.1.14:
Note 1 to entry: Devices that are designed to only receive electromagnetic fields from other sources are not
considered as intentional radiators. For example, near field communication (NFC) transducers are not considered as
intentional radiators.
4 Limits
4.1 General
Replace the first paragraph of 4.1 with the following new paragraph and note:
The basic restrictions or reference levels for the general public of either IEEE C95.1-2005 or
ICNIRP (ICNIRP 2020 and ICNIRP 2010) are used, see Annex C.
NOTE Reference levels have been taken from ICNIRP publications however, basic restrictions of IEEE and ICNIRP
are essentially the same.
6 Measurement procedure for the Van der Hoofden test
6.1 General
Replace the first sentence of 6.1 with the following new sentence:
The assessment method is based on basic restrictions given in both ICNIRP 2020 and ICNIRP
2010, or in IEEE C95.1-2005.
7.2.3 Determination of the low-power exclusion level
Replace the third sentence of 7.2.3 with the following new sentence:
___________
Numbers in square brackets refer to the Bibliography.

 IEC 2022
For instance for ICNIRP 2020, general public exposure, the worst case low-power exclusion
level is 20 mW for head and trunk.

C.2 ICNIRP
Replace the existing Clause C.2, including its title, with the following new Clause C.2:
C.2 ICNIRP basic restrictions
C.2.1 Basic restrictions - SAR
Table C.1 provides the basic restrictions (SAR) for general public exposure to time varying
electric and magnetic fields for frequencies between 100 kHz and 300 GHz (see [1]):
Table C.1 – Basic restrictions for general public exposure to time varying
electric and magnetic fields for frequencies between 100 kHz and 300 GHz
Frequency range Average SAR Localised SAR Localised SAR
(whole body) (head and trunk) (limbs)
W/kg W/kg W/kg
100 kHz to 6 GHz 0,08 2 4
a a
> 6 GHz to 300 GHz 0,08 NA NA
a
NA signifies "not applicable" and does not need to be taken into account when determining compliance.

C.2.2 Basic restrictions – Internal electric field
Table C.2 provides the basic restrictions for general public exposure to time varying electric
and magnetic fields for frequencies up to 10 MHz (see [1], [2]):
Table C.2 – Basic restrictions for general public exposure to time varying
electric and magnetic fields for frequencies up to 10 MHz
Exposure characteristic Frequency range Internal electric field
V/m
CNS tissue of the head 1 Hz to 10 Hz 0,1/f
10 Hz to 25 Hz 0,01
−4
25 Hz to 1 kHz 4 × 10 f
1 kHz to 3 kHz 0,4
−4
3 kHz to 10 MHz 1,35 × 10 f
All other tissues (head and body) 1 Hz to 3 kHz 0,4
−4
3 kHz to 10 MHz 1,35 × 10 f
f is the frequency in Hz.
All values are RMS.
C.2.3 Changes introduced by ICNIRP 2020 with respect to ICNIRP 1998 and ICNIRP 2010
Changes for the basic restrictions (SAR) from ICNIRP 1998 to ICNIRP 2020 have been made
by (i) extending the considered spectrum up to 100 GHz, while (ii) between 100 kHz and 6 GHz
limits remain unchanged and (iii) for frequencies above 6 GHz it has been found that they do
not need to be taken into account when determining compliance.
