Evaluation of human exposure to electromagnetic fields from a stand-alone broadcast transmitter (30 MHz - 40 GHz)

IEC 62577:2009 applies to a single stand-alone broadcast transmitter operating in the frequency range 30 MHz to 40 GHz when put on the market. The objective of the standard is to specify, for such equipment operating in typical conditions, the method for assessment of compliance distances according to the basic restrictions (directly or indirectly via compliance with reference levels) related to human exposure to radio frequency electromagnetic fields.
NOTE 1 - This standard only applies to broadcast transmitters being placed on the market (type approval) and does not apply to broadcast transmitters being commissioned or placed into service.
NOTE 2 - Compliance certification depends on the policy of national regulatory bodies.

Evaluation de l'exposition des personnes aux champs électromagnétiques provenant des émetteurs de radiodiffusion isolés (30 MHz - 40 GHz)

La CEI 62577:2009 s'applique à un émetteur de radiodiffusion isolé fonctionnant dans la gamme de fréquence de 30 MHz à 40 GHz lors de la mise en marché. Le but de cette norme est de spécifier, pour de tels équipements fonctionnant dans des conditions typiques, la méthode d'évaluation des distances de conformité relatives aux restrictions de bases (directement ou indirectement via la conformité aux niveaux de référence) liées à l'exposition du corps humain aux champs électromagnétiques de fréquences radio.
NOTE 1 Cette norme s'applique seulement aux émetteurs de radiodiffusion lors de la mise en marché (approbation de type) et ne s'applique pas aux émetteurs de radiodiffusion lors de la mise en service.
NOTE 2 La certification de conformité dépend de la politique des organismes de réglementation nationaux.

EVALUATION OF HUMAN EXPOSURE TO ELECTROMAGNETIC FIELDS
FROM A STAND-ALONE BROADCAST TRANSMITTER
(30 MHz – 40 GHz)
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
International Standard IEC 62577 has been prepared by IEC technical committee 106:
Methods for the assessment of electric, magnetic and electromagnetic fields associated with
human exposure, and CENELEC TC 106X: Electromagnetic fields in the human environment.
The text of this standard is based on the following documents:
FDIS Report on voting
106/176/FDIS 106/179/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
