Assessment of lighting equipment related to human exposure to electromagnetic fields - Product family standard (IEC 62493:2009)

This International Standard applies to the assessment of lighting equipment related to human exposure to electromagnetic fields. The assessment consists of the induced current density for frequencies from 20 kHz to 10 MHz and the specific absorption rate (SAR) for frequencies from 100 kHz to 300 MHz around lighting equipment. Included in the scope of this standard are: - all lighting equipment for general lighting with a primary function of generating and/or distributing light intended for illumination purposes, and intended either for connection to the low voltage electricity supply or for battery operation; used indoor and/or outdoor. General lighting equipment means all industrial, residential and public and street lighting; - lighting part for general lighting of multi-function equipment where one of the primary functions of this is illumination; - independent auxiliaries exclusively for the use with lighting equipment. Excluded from the scope of this standard are: - lighting equipment for aircraft and airfields; - lighting equipment for road vehicles; (except lighting used for the illumination of passenger compartments in public transport) - lighting equipment for agriculture; - lighting equipment for boats/vessels; - photocopiers, slide projectors; - apparatus for which the requirements of electromagnetic fields are explicitly formulated in other IEC standards; This standard does not apply to built-in components for luminaires such as electronic control gear.

Evaluation d'un équipement d'éclairage relativement à l'exposition humaine aux champs magnétiques - Norme des familles de produits (CEI 62493:2009)

La CEI 62493:2009 traite de l'évaluation d'un équipement d'éclairage relativement à l'exposition humaine aux champs électromagnétiques. L'évaluation comprend la densité du courant induit pour les fréquences comprises entre 20 kHz et 10 MHz et le débit d'absorption spécifique (SAR) pour les fréquences comprises entre 100 kHz et 300 MHz autour de l'équipement d'éclairage. La présente norme ne s'applique pas aux composants intégrés dans des luminaires, tels que les appareillages électroniques.

Ocenjevanje opreme za razsvetljavo glede izpostavljenosti ljudi elektromagnetnim poljem - Standard za skupino izdelkov (IEC 62493:2009)

Ta mednarodni standard velja za ocenjevanje opreme za razsvetljavo glede izpostavljenosti ljudi elektromagnetnim poljem. Ocenjevanje je sestavljeno iz gostote induciranega toka za frekvence od 20 kHz do 10 MHz in določene stopnje absorpcije (SAR) za frekvence od 100kHz do 300 MHz okoli opreme za razsvetljavo. V področje uporabe tega standarda je vključeno: - vsa oprema za razsvetljavo za splošno razsvetljavo s prvotnim namenom za proizvodnjo in/ali razširitvijo svetlobe, predvidena za namene razsvetlitve, bodisi s priklopom na nizkonapetostno oskrbo z električno energijo ali z delovanjem na baterijo, za notranjo in/ali zunanjo uporabo. Splošna oprema za razsvetljavo pomeni: vso industrijsko, bivalno in javno razsvetljavo; - svetilni del splošne razsvetljave večnamenske opreme, kjer je ena izmed glavnih funkcij osvetljevanje; - neodvisno dodatno opremo, ki se uporablja izključno za opremo za razsvetljavo. Iz področja uporabe tega standarda je izvzeto: - oprema za razsvetljavo za letala in letališča; - oprema za razsvetljavo za cestna vozila (razen razsvetljave, uporabljene za razsvetlitev prostorov za potnike v javnem prevozu); - oprema za razsvetljavo za kmetijstvo; - oprema za razsvetljavo za čolne/plovila, fotokopirne stroje, diaprojektorje; - naprave, za katere so zahteve o elektromagnetnih poljih natančno oblikovane v drugih IEC standardih. Ta standard ne velja za vgradne sestavne dele za svetila, kot je na primer elektronska kontrolna naprava.

ASSESSMENT OF LIGHTING EQUIPMENT RELATED TO HUMAN
EXPOSURE TO ELECTROMAGNETIC FIELDS


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 determining 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
)
1
general public given by ICNIRP:1998 [1] , IEEE C95.1:2005 and IEEE C95.6:2002[2]. The
exposure levels with which to comply are basic restrictions (both ICNIRP- and IEEE-based).
NOTE 1 Maximum permissible exposure levels (IEEE-based) or reference levels (ICNRIP-based) are not used.
Based on the lighting equipment operating properties, the frequency range of the applicable
basic restrictions can be limited as follows:
• induced current density between 20 kHz to 10 MHz;
• specific absorption rate (SAR) between 100 kHz to 300 MHz;
• power density is outside the scope.
NOTE 2 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.
The exposure limits given in Annex C (informative) are for information only, do not comprise an
exhaustive list and are valid only in certain regions of the world. It is the responsibility of users of
this standard to ensure that they use the current version of the limit values specified by the
applicable national authorities.
