Foreword
This European Standard was prepared by the Technical Committee CENELEC TC 106X,
Electromagnetic fields in the human environment.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50499 on
2008-10-21.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2009-11-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2011-11-01
This European Standard has been prepared under Mandate M/351 given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of
EC Directive 2004/40/EC.
This standard is intended to be a standard under which other standards related to the assessment of a
work place can be used.
The approaches outlined in this standard, are intended to be simple, allowing most employers to make an
assessment with the minimum of technical knowledge and effort.

1 Scope
The scope of this European Standard is to provide a general procedure in order to assess workers’
exposure to electric, magnetic and electromagnetic fields in a work place to demonstrate compliance with
exposure limit values and action values as stated in the Council and European Parliament Directive
2004/40/EC.
The purpose of this European Standard is to
- specify how to perform an initial assessment of the levels of workers' exposure to electromagnetic
fields (EMF), if necessary including specific exposure assessment of such levels by measurements
and/or calculations,
- determine whether it is necessary to carry out a detailed risk assessment of EMF exposure.
This European Standard can be used by employers for the risk assessment and, where required,
measurement and/or calculation of the exposure of workers. Based on specific workplace
standards it can be determined whether preventive measures/actions must be taken to comply
with the provisions of the Directive.
The frequencies covered are from 0 Hz to 300 GHz.
NOTE 1  This European Standard is written under Mandate M/351 and relates to the exposure limits as specified in the Directive
2004/40/EC. It is intended to protect workers from risks to their health and safety arising or likely to arise from exposure to
electromagnetic fields (0 Hz to 300 GHz) during their work. However, this and other directives may include additional measures for
the protection of specific groups of workers and/or specific work places for which the employer is required to investigate other
protective measures as a part of the overall risk assessment. See Annex A.
NOTE 2  The Council and European Parliament Directive 2004/40/EC will be transposed into national legislation in all the
EU member countries. It is recommended that users of this standard consult the national legislation related to this transposition in
order to identify the national regulations and requirements. These national regulations and requirements may have additional
requirements that are not covered by this standard.
