European foreword
This document (EN 50665:2017) has been prepared by the Technical Committee CENELEC/TC 106X
“Electromagnetic fields in the human environment”.
The following dates are fixed:
– latest date by which the EN has to be implemented (dop) 2018-09-11
at national level by publication of an identical

national standard or by endorsement
– latest date by which the national standards conflicting (dow) 2020-09-11
with the EN have to be withdrawn

This European Standard has to be read in conjunction with EN 62311:2008 “Assessment of electronic and
electrical equipment related to human exposure restrictions for electromagnetic fields (0 Hz to 300 GHz)”.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CENELEC by the European Commission and
the European Free Trade Association and, and supports essential requirements of the Radio Equipment
Directive 2014/53/EU (M/536) and the Low Voltage Directive 2014/35/EU (M/511).
For relationships with EU Directives, see informative Annexes ZZA and ZZB, which are an integral part of
this document.
1 Scope
This European Standard applies to electronic and electrical equipment for which no dedicated harmonized
product- or product family standard, or standard relating to low power equipment, regarding human exposure
to electromagnetic fields exists. If such a standard does exist then it shall be used and this standard shall
not. Annex A lists such harmonized standards available at the time of writing This list may change with time.
The current list of standards harmonized under each Directive should be consulted at the time of use of this
standard.
The object of this generic standard is to provide a route for evaluation of such equipment against limits on
human exposure to electric, magnetic and electromagnetic fields, and induced and contact current.
The frequency range covered is 0 Hz to 300 GHz.
This standard is intended to cover both intentional and non-intentional radiators.
NOTE 1 Other standards can apply to products covered by this document. In particular, this document is not
designed to evaluate the electromagnetic compatibility with other equipment; nor does it reflect any product safety
requirements other than those specifically related to human exposure to electromagnetic fields.
NOTE 2 This standard addresses only human exposure from the specific equipment under evaluation. There is an
applicable putting-into service/in situ standard for equipment used by workers when at work:
EN 50664:2017. Generic standard to demonstrate the compliance of equipment intended for use only by workers with
limits on human exposure to electromagnetic fields (0 Hz - 300 GHz), when put into service or in situ.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content constitutes
requirements of this document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
EN 62311:2008, Assessment of electronic and electrical equipment related to human exposure restrictions
for electromagnetic fields (0 Hz - 300 GHz)
Council Recommendation 1999/519/EC of 12 July 1999, on the limitation of exposure of the general public to
electromagnetic fields (0 Hz to 300 GHz), Official Journal, L199, of 1999-7-30, p.59-70

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
action levels
levels provided for practical exposure assessment purposes. They are derived from exposure limit values.
Respect of the action level will ensure respect of the relevant exposure limit value. If the action level is
exceeded, it does not necessarily follow that the exposure limit value will be exceeded
3.2
basic restrictions
restrictions on exposure of the general public to electric, magnetic and electromagnetic fields that are based
directly on established health effects and biological considerations
3.3
exposure limit values
restrictions on exposure of workers to electric, magnetic and electromagnetic fields that are based directly on
established health effects and biological considerations
3.4
reference levels (or derived reference levels)
levels provided for practical exposure assessment purposes. They are derived from basic restrictions.
Respect of the reference level will ensure respect of the relevant basic restriction. If the reference level is
exceeded, it does not necessarily follow that the basic restriction will be exceeded
4 Exposure conditions
Equipment which meets the limits for general public exposure as given in this document (Clause 5) will
automatically meet the limits for workers without further testing.
Equipment which meets the limits for workers will not necessarily meet the limits for the general public and,
unless intended only for workers’ use when at work, equipment shall also be tested against general public
limits.
Equipment intended only for use by workers when at work shall have this condition clearly identified in the
user instructions. This use condition shall be identified in the test report.
All intended operating conditions as well as the reasonably foreseeable conditions of human exposure from
the equipment shall be taken into account in the evaluation.
The reasonably foreseeable conditions of exposure should be based on realistic exposure and/or installation
parameters representative of all readily-predictable human and system behaviour such as the duration of
exposure, time varying of transmitted power, simultaneously operated frequency bands and time averaging
as defined in normative limits.
