Overview

IEC 62493:2015 is the International Electrotechnical Commission (IEC) standard dedicated to the assessment of lighting equipment concerning human exposure to electromagnetic fields (EMF). This standard covers critical frequency ranges from 20 kHz to 300 MHz and establishes evaluation methods for the induced internal electric field and the specific absorption rate (SAR) near lighting devices. The 2015 edition of IEC 62493 replaces the previous 2009 version, incorporating significant technical updates to ensure state-of-the-art compliance and safety guidance for manufacturers and regulatory professionals.

Key Topics

• Human Exposure Assessment
  IEC 62493 specifies measurement and evaluation techniques for determining the safety of lighting equipment regarding EMF exposure. It focuses on:

  • Induced Internal Electric Field: Measured in lighting equipment emissions from 20 kHz to 10 MHz.
  • Specific Absorption Rate (SAR): Evaluated for frequencies between 100 kHz and 300 MHz to assess thermal effects on human tissue.

• Updated Compliance Requirements
  Notable technical revisions in this edition include:

  • Identification of lighting product types that comply without requiring additional testing.
  • Removal of the previous prerequisite for compliance with CISPR-15.
  • Integration of the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines updated in 2010, specifically relevant to frequencies up to 100 kHz.
  • Enhanced guidance on the Van der Hoofden test head measurement method to improve reproducibility and accuracy of results.
  • Procedures for demonstrating compliance for lighting equipment featuring intentional radiators (devices emitting radio waves by design).

• Measurement Techniques
  The standard outlines the Van der Hoofden test, which uses a specialized head-shaped probe for assessing electric fields induced by lighting equipment. It details setup requirements, ambient conditions for testing, measurement distances, and instrumentation accuracy.

• Assessment of Intentional Radiators
  IEC 62493 includes specific procedures for assessing lighting devices that incorporate intentional radio frequency transmitters. This ensures that both unintentional and intentional emissions are adequately evaluated for safety.

Applications

• Lighting Equipment Manufacturers
  Utilize IEC 62493 to design, test, and certify lighting products, ensuring compliance with international EMF exposure limits while maintaining product safety and market acceptance.

• Regulatory Authorities
  Employ the standard as a benchmark to evaluate lighting products' safety related to electromagnetic field exposure, supporting enforcement of health and safety regulations.

• Testing Laboratories
  Apply the standardized measurement methods, including the Van der Hoofden test, to perform consistent and accurate EMF exposure assessments on lighting devices.

• Product Designers and Engineers
  Reference this standard during product development to minimize EMF emissions and meet human health safety guidelines effectively.

Related Standards

• CISPR-15 – Previously linked as a prerequisite, this standard addresses electromagnetic disturbances from lighting equipment but is no longer mandatory for IEC 62493 compliance.

• ICNIRP Guidelines (2010 & 2020 Revisions) – International guidelines for limiting exposure to non-ionizing radiation; IEC 62493 aligns with these for frequencies up to 100 kHz and integrates updated safety thresholds.

• IEEE EMF Standards – Complementary guidance on electromagnetic field exposure; some assessment methods and limits referenced in IEC 62493 align with IEEE recommendations.

• EMF Product Standards for Base Stations and Body-Worn Equipment – Used in assessing radiation from intentional radiators, integrated within the IEC 62493 framework for comprehensive safety evaluation.

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.

INTRODUCTION
This International Standard establishes a suitable evaluation method for the influence of the
electromagnetic fields in the space around the equipment mentioned in the scope, and
defines standardized operating conditions and measurement distances.
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:1998 [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).
Based on the lighting equipment operating properties, the frequency range of the applicable
basic restrictions can be limited as follows:
• internal electric field between 20 kHz and 10 MHz;
• specific absorption rate (SAR) between 100 kHz and 300 MHz;
• power density is outside the scope.
NOTE Operating frequencies of lighting equipment are higher than 20 kHz to avoid audible noise and infrared
interference. Frequency contributions above 300 MHz can be neglected.
This standard is not meant to supplant definitions and procedures specified in exposure
standards, but it is aimed at supplementing the procedure already specified for compliance
with exposure.

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.

INTRODUCTION
This International Standard establishes a suitable evaluation method for the influence of the
electromagnetic fields in the space around the equipment mentioned in the scope, and
defines standardized operating conditions and measurement distances.
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:1998 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).
Based on the lighting equipment operating properties, the frequency range of the applicable
basic restrictions can be limited as follows:
• internal electric field between 20 kHz and 10 MHz;
• specific absorption rate (SAR) between 100 kHz and 300 MHz;
• power density is outside the scope.
NOTE Operating frequencies of lighting equipment are higher than 20 kHz to avoid audible noise and infrared
interference. Frequency contributions above 300 MHz can be neglected.
This standard is not meant to supplant definitions and procedures specified in exposure
standards, but it is aimed at supplementing the procedure already specified for compliance
with exposure.

electric discharge lamp in which the light-producing arc is stabilized by wall temperature and
the arc has a bulb wall loading in excess of 3 W/cm
Note 1 to entry: HID lamps include groups of lamps known as high pressure mercury, metal halide and high
pressure sodium lamps.
Note 2 to entry: This note applies to the French language only.
3.1.10
high-pressure lamp
high intensity discharge lamp in which the major portion of the light is produced, directly or
indirectly, by radiation from mercury or sodium vapour operating at relatively high levels of
partial pressure
3.1.11
independent auxiliary
auxiliaries consisting of one or more separate elements designed so that it can be mounted
separately outside a luminaire, with protection according to the marking of the auxiliaries and
without any additional enclosure
EXAMPLE: Examples are dimmers, transformers and convertors for incandescent lamps or LED light sources,
ballasts for discharge lamps (including fluorescent lamps) and semi-luminaires for compact fluorescent lamps,
incandescent lamps or LED light sources
Note 1 to entry: This may consist of a built-in auxiliary housed in a suitable enclosure which provides all the
necessary protection according to its markings.
3.1.12
independent lamp controlgear
independent electronic converter
lamp controlgear consisting of one or more separate elements so designed that it can be
mounted separately outside a luminaire, with protection according to the marking of the lamp
controlgear and without any additional enclosure
Note 1 to entry: This may consist of a built-in lamp controlgear housed in a suitable enclosure that provides all
the necessary protection according to its markings.
3.1.13
integral lamp controlgear
lamp controlgear which forms a non-replaceable part of a luminaire and which cannot be
tested separately from the luminaire
3.1.14
intentional radiator
any device that is designed to produce electromagnetic fields on purpose in order to provide
functions such as wireless communication, control, detection, etc.
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.
3.1.15
lamp controlgear
one or more components between the supply and one or more lamps which may serve to
transform the supply voltage, limit the current of the lamp(s) to the required value, provide
starting voltage and preheating current, prevent cold starting, correct power factor or reduce
radio interference

4 Limits
4.1 General
The basic restrictions or reference levels for the general public of either IEEE C95.1-2005 or
ICNIRP 1998 (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.
Lighting equipment shall comply with the Van der Hoofden test limit (4.2.3), unless it is
inherently compliant (4.2.2). If equipped with intentional radiators, it shall also pass the
assessment procedure for intentional radiators (4.3). An overview of the routes to
demonstrate compliance against these limits is given in Figure1.
4.2 Unintentional radiating part of lighting equipment
4.2.1 General
This subclause 4.2 applies for lighting equipment, excluding the intentional radiating part (as
far as applicable).
