European foreword
This document (CLC/TR 50713:2021) has been prepared by CLC/TC 106X “Electromagnetic fields in the human
environment”.
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.
Introduction
Directive 2014/53/EU (Radio Equipment Directive, RED) and Directive 2014/35/EU (Low Voltage Directive,
LVD) require that equipment meets the electromagnetic fields (EMF) exposure requirements when used as
intended as well as under reasonably foreseeable conditions. Consequently, all relevant product standards are
to be revised to meet the new requirements introduced in these directives.
Both the above-mentioned directives introduce new wordings such as “conditions of use which can be
reasonably foreseen” as well as “reasonably foreseeable conditions” which are considered synonymous
phrases. These new wordings could be open to different interpretations. Therefore, there is a need for
clarification of what “conditions of use which can be reasonably foreseen” and its synonyms “reasonably
foreseeable conditions” as well as “reasonably foreseeable use” mean when dealing with the EMF compliance
of different product categories and applications.
Reasonably foreseeable conditions not only take into account the user behaviour but also exposure conditions
representative of all readily-predictable human and system behaviour including parameters such as the duration
of exposure, time variability of transmitted power, simultaneously operated frequency bands, availability of
manufacturer-approved accessories, and time averaging as defined in normative limits and exposure guidelines.
This document addresses only the EMF assessment perspective (both measurement and calculation).
This document refers to the wording of the underlying directives. The considerations are restricted to the EMF
exposure assessment and not intended to be applied beyond EMF exposure assessment.
1 Scope
This document illustrates good practices and provides guidance with regard to the term “reasonably foreseeable
use” as it relates to product compliance assessment standards concerning the exposure of humans to electric,
magnetic and electromagnetic fields (EMF) as required in the Radio Equipment Directive (RED) and Low
Voltage Directive (LVD). Other safety aspects and requirements from other directives are not covered by this
document.
This document uses the term “reasonably foreseeable use”, which in the context of this document is
interchangeable with the terms “reasonably foreseeable conditions” and “conditions of use which can be
reasonably foreseen”. The document provides guidance that is not specific to individual equipment.
The document covers both occupational and general public use of equipment and also provides a rationale for
the distinction between occupational use and use by the general public.
This document is limited to the standards in the scope of TC106X.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at http://www.electropedia.org/
3.1
intended use
use of equipment in accordance with the information for use or user training provided by the manufacturer
Note1 to entry: According to the RED, intended use requires proper installation and maintenance of radio equipment and
that radio equipment has to be used for its intended purpose.
Note 2 to entry: Some usage of a product, shown for advertising purpose only, might not be intended to be repeated by
the user and is therefore not part of the intended use.
[SOURCE: CENELEC Guide 32:2016, definition 4.8, modified; IEV 903-01-13, modified]
3.2
reasonably foreseeable use
intended use as well as use of equipment in conditions, which results from lawful and readily predictable human
and system behaviour that can be anticipated by the manufacturer
Note 1 to entry: Use conditions explicitly excluded by the manufacturer in the information for use or user training, but
nevertheless reasonably foreseeable under the assumption that the user has not read the information for use or has not
followed training instructions, are deemed to represent reasonably foreseeable misuse and such conditions fall outside this
definition.
Note 2 to entry: This document uses the term “reasonably foreseeable use”. In this context, the terms “reasonably
foreseeable conditions”, “reasonably foreseeable use” and “conditions of use which can be reasonably foreseen” are
interchangeable.
3.3
reasonably foreseeable misuse
any use conditions not included in “reasonably foreseeable use” or “unreasonable misuse”, including use
conditions which contradict the information for intended use or user training, even if considered reasonably
predictable human behaviour
Note 1 to entry: Any potential misuse shall not be considered for the compliance assessment of equipment regarding
human exposure to EMF.
[SOURCE: CENELEC Guide 32:2016, definition 4.11, modified; IEV 903-01-14, modified]
3.4
unreasonable misuse
use conditions, which are based on not predictable or unlawful human behaviour
3.5
general public
individuals of all ages and of differing health statuses, which may include particularly vulnerable groups or
individuals, and who might have no knowledge of or control over their exposure to EMF
Note 1 to entry: In many cases, members of the general public are unaware of their exposure to EMF. These
considerations underlie the adoption of more stringent exposure restrictions for the public than for workers while they are
occupationally exposed.
Note 2 to entry: Consumers are considered to be members of general public.
Note 3 to entry: Conscious medical treatment to a maximum dosage is excluded.
3.6
professional use
use conditions intended only for trained experts or instructed persons
[SOURCE: IEV 851-11-12 modified]
3.7
worker
any person employed by an employer, including trainees and apprentices but excluding domestic servants
Note 1 to entry: The formal distinction between general public and worker is often given in national legislation.
[SOURCE: Council Directive 89/391/EEC of 12 June 1989 on the introduction of measures to encourage
improvements in the safety and health of workers at work]
4 Distinction between general public and workers
Directive 89/391/EEC defines worker as any person employed by an employer, including trainees and
apprentices but excluding domestic servants; an employer is any natural or legal person who has an
employment relationship with the worker and has responsibility for the undertaking and/ or establishment.
Directive 89/391/ECC as well as Directive 2013/35/EU require information and training for workers who are
likely to be exposed to risks from EMF at work.
Thus, the exposure guidelines distinguish whether the worker is aware of the EMF exposure or not and whether
the person is professionally trained. What can be presumed as reasonably foreseeable use regarding a worker
who is aware of the EMF exposure and professionally trained about the EMF exposure is different from what
can be expected from an unaware and untrained worker. If workers are unaware of their exposure to EMF they
are treated like members of the general public. The reference levels and basic restrictions for the exposure of
the general public to electric, magnetic, and electromagnetic fields are stricter than for occupational exposure.
Equipment that is compliant with the requirements for general public is deemed to be usable for workers.
5 Intended Use
This document considers mainly the placing on the market of equipment. The intended use implies proper
installation and maintenance as well as using equipment for its intended purpose.
NOTE 1 The use of the equipment includes relevant accessories and components, as long as the mode of operation is
approved by the manufacturer.
The manufacturer should provide sufficient documentation on the intended use of the equipment in a clear,
understandable and intelligible language for general public and workers. Any labelling should be clear and
understandable. Such user documentation may include a description of manufacturer-approved accessories
and components, including software, which allow the equipment to operate as intended.
NOTE 2 The Blue Guide, in Chapter 3.1.4, provides more details on how the instructions and safety information is
expected to be provided.
6 Reasonably foreseeable use
6.1 Fundamental elements of reasonably foreseeable use
Reasonably foreseeable use includes the reasonably foreseeable conditions under which a device is used.
The devices are required to meet applicable regulatory standards including EMF compliance. In the case of
electromagnetic fields (EMF) exposure assessment, when the equipment operated by the user, three
fundamental elements can easily be recognized:
1) The Device/Equipment,
2) The User,
3) The way the device is used, i.e. the
