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.

The main task of IEC technical committees is to prepare International Standards. However, a

technical committee may propose the publication of a technical report when it has collected

data of a different kind from that which is normally published as an International Standard, for

example "state of the art".

IEC/TR 62493-1, which is a technical report, has been prepared by IEC technical committee

34: Lamps and related equipment.

INTRODUCTION

In 2011 it was decided by VDE and ZVEI to start a measurement campaign for testing a broad

range of different types of luminaires with different lamp technologies against the new EMF

(Electromagnetic Fields) standard IEC 62493:2009 (identical to EN 62493:2010-02). The goal

was to get an overview on the EMF measurement results dependent on different lamp

technologies used in current luminaires on the market. For this measurement campaign only

the test procedure with the so called Van der Hoofden head in the frequency range from

20 kHz to 10 MHz was used.

The goal of this campaign is to identify construction details of lighting equipment which are

critical for the EMF measurements.

NOTE The VDE Testing and Certification Institute is a part of the VDE Association for Electrical, Electronic &

Information Technologies. The VDE Testing and Certification Institute is accredited on a national and international

level for the area of testing and certification of electrotechnical equipment, components and systems. ZVEI is the

German Industry Association for the Electrical Industry.

1 Scope

This part of the IEC 62493 series presents an overview on EMF measurement results

dependent on different lamp technologies used in current luminaires. For the measurement

only the test procedure with the so called Van der Hoofden head in the frequency range from

20 kHz to 10 MHz was used.
2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and

are indispensable for its application. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any
amendments) applies.

3 Test procedure
The testing of luminaires has been performed according to the requirements of

IEC 62493:2009. The luminaires have been placed over the test head at the distance d as

required by the standard. Figure 1 shows the set-up in principal.
