Overview

EN 62479:2010 (adoption of IEC 62479:2010) defines simple conformity assessment methods for low‑power electronic and electrical equipment with respect to human exposure to electromagnetic fields (EMF) in the 10 MHz to 300 GHz range. It provides streamlined routes to demonstrate compliance with basic restrictions (e.g., SAR, current density, power density) and is intended for devices where exposure is expected to be low. If a device cannot be shown compliant using EN 62479 methods, other EMF product standards such as IEC 62311 may be applied.

Key topics and requirements

• Scope and purpose: Simple, pragmatic assessment methods tailored for low‑power transmitters and electronic equipment to evaluate EMF exposure risks.
• Frequency range: Covers EMF from 10 MHz to 300 GHz, matching typical RF and microwave device operation.
• Low‑power exclusion level: Provides the concept and methods to determine a device’s low‑power exclusion level (Pmax) - a threshold below which simple assessment is acceptable rather than full SAR or detailed evaluation.
• Exposure quantities: Relates compliance to the applicable basic restrictions (SAR, current density, power density) and considers time‑averaging requirements defined by regional recommendations.
• Assessment methods: Routes include evaluation based on available antenna power, average total radiated power, multiple-source exposure scenarios, and measurement/estimation workflows.
• Documentation and reporting: Specifies content of an EMF assessment report, including device data, measurement methods, and treatment of measurement uncertainty.
• Special topics (informative annexes): Derivation of exclusion levels from ICNIRP/IEEE limits, alternative exclusion levels for devices used close to the body, pulsed‑field compliance, and references to ISO/IEC 17025 principles for testing labs.

Practical applications and users

• Who uses it: RF product manufacturers (portable wireless devices, IoT modules, wearables), compliance engineers, test laboratories, certification bodies, and regulatory authorities assessing low‑power EMF compliance.
• Why use it: Enables quicker, cost‑effective conformity assessment for many low‑power products without full SAR testing; helps manufacturers demonstrate compliance with EU recommendations and national regulations.
• Typical devices: Small transmitters, short‑range wireless modules, personal communication devices, low‑power IoT endpoints and accessories where radiated power and exposure are limited.

Related standards

• IEC 62311 - more comprehensive assessment for equipment related to human exposure (0 Hz–300 GHz).
• EN 50371:2002 - superseded by EN 62479.
• Council Recommendation 1999/519/EC - referenced for EU basic restrictions and time averaging.
• ISO/IEC 17025 - relevant for testing laboratory competence and report quality.

EN 62479:2010 is a practical standard for streamlined EMF exposure assessment of low‑power equipment, helping manufacturers and labs efficiently achieve EMF compliance.

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.

ASSESMENT OF THE COMPLIANCE OF LOW-POWER
ELECTRONIC AND ELECTRICAL EQUIPMENT
WITH THE BASIC RESTRICTIONS RELATED TO HUMAN
EXPOSURE TO ELECTROMAGNETIC FIELDS
(10 MHz to 300 GHz)
1 Scope
This International Standard provides simple conformity assessment methods for low-power
electronic and electrical equipment to an exposure limit relevant to electromagnetic fields
(EMF). If such equipment cannot be shown to comply with the applicable EMF exposure
requirements using the methods included in this standard for EMF assessment, then other
standards, including IEC 62311 or other (EMF) product standards, may be used for conformity
assessment.
2 Normative references
The following referenced documents are indispensable for the application 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.

restrictions for electromagnetic fields (0 Hz – 300 GHz)
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
available antenna power
the maximum power, averaged over a time interval equal to the averaging time, supplied to
the antenna feed line that can be theoretically delivered by a source having an impedance of
positive real part to a directly connected load when the impedance of the load is widely varied
NOTE 1 The available antenna power is obtained when the resistance of the load is equal to that of the source
and its reactance is equal in magnitude but of opposite sign. However, other scenarios are possible e.g. if the PA
monitors the current rather than the actual power, a changing antenna impedance (when DUT is operated close to
the body) might actually cause a higher output power than the matched load. Then, a push-pull analysis with varied
realistic loads (according to antenna impedance in the vicinity of the body) should be performed.
NOTE 2 In some cases, conditions such as overheating or overvoltage prevent the available antenna power from
being obtained.
NOTE 3 Time average shall be taken during continuous or maximum duty cycle transmission at maximum power
to the extent possible for a given technology.
1)
NOTE 4 Adapted from IEC 60050-702:1992 [11] , 702-07-10.
NOTE 5 Antenna feed line is defined by IEC 60050-712:1992 [12], 712-06-01.

3.2
average total radiated power
the time average of the total radiated power over a time interval equal to the averaging time.
This time average is taken during continuous or maximum duty cycle transmission at
maximum power to the extent possible for a given technology
NOTE If the user is in the reactive near field of the antenna, the presence of the user may result in a change in
the total radiated power due to a change in the antenna impedance. In this case, the average total radiated power
must be the maximum possible power in the presence of the user.
3.3
averaging time
t
avg
the appropriate time over which exposure is averaged for purposes of determining compliance
with exposure limits
3.4
basic restriction
restriction(s) on exposure to time-varying electric, magnetic, and electromagnetic fields that are based
directly on established health effects
NOTE Depending upon the frequency of the field, the physical quantities used to specify these restrictions are
current density, specific absorption rate (SAR), and power density.
3.5
conformity assessment
demonstration that specified requirements relating to a product, process, system, person or
body are fulfilled
NOTE The subject field of conformity assessment includes activities such as testing, inspection and certification,
as well as the accreditation of conformity assessment bodies.
[ISO 17000:2004 [14], definition 2.1, modified]
3.6
information technology equipment
ITE
any equipment which has a primary function of either (or a combination of) entry, storage,
display, retrieval, transmission, processing, switching, or control, of data and of
telecommunication messages and which may be equipped with one or more terminal ports
typically operated for information transfer
EXAMPLE Types of ITE include data processing equipment, office machines, electronic business equipment and
telecommunication equipment.
3.7
low-power equipment
equipment where the available antenna power and/or the average total radiated power is less
than or equal to the low-power exclusion level
3.8
low-power exclusion level
P
max
specified condition on device output power, which may also depend on other variables such
as frequency and distance of radiating source from persons, such that the exposure level
produced by the source will not exceed a specific basic restriction. If the device output power
is less than P , then the device is deemed to comply with the basic restrictions

multimedia equipment
MME
equipment that has the function of information technology equipment (ITE), audio, video or
broadcast-receiving equipment, interaction and/or communication with the user of the product
or combinations of these functions

[CISPR 32____ [9], definition 3.1.17]
3.10
peak radiated power
the maximum instantaneous radiated power
3.11
power density
the power passing through an element of surface normal to the direction of propagation of
energy of an electromagnetic wave divided by the area of the element

NOTE Power density is expressed in watts per square meter.
3.12
pulse repetition frequency
PRF
the number of pulses transmitted per unit time
3.13
specific absorption
SA
energy absorbed by (dissipated in) an incremental mass contained in a volume element of
biological tissue when exposure to a radio frequency electromagnetic field occurs
NOTE Specific absorption is expressed in joules per kilogram.
3.14

biological tissue when exposure to a radio frequency electromagnetic field occurs
NOTE SAR is expressed in watts per kilogram.
3.15
total radiated power
the total power emitted by the equipment in the form of electromagnetic fields in the absence
of any nearby objects (e.g. a human body)
NOTE For transmitters that use antennas, the total radiated power is independent of antenna gain.
3.16
unintentional radiator
non-intentional radiator
electrical or electronic equipment that radiates radio frequency (RF) energy, even though the
emission is not a deliberate or necessary part of its function
EXAMPLE Examples of unintentional radiators include all types of ITE without antenna and/or wireless radio
transmission function.

4 Conformity assessment methods
4.1 General considerations
Compliance of electromagnetic emissions from electronic and electrical equipment with the
basic restrictions usually is determined by measurements and, in some cases, calculation of
the exposure level. If the electrical power used by or radiated by the equipment is sufficiently
low, the electromagnetic fields emitted will be incapable of producing exposures that exceed
the basic restrictions. This standard provides simple EMF assessment procedures for this low
power equipment.
Any relevant compliance assessment procedure which is consistent with the state of the art,
reproducible and gives valid results can be used.
For transmitters intended for use with more than one antenna configuration option, the
combination of transmitter and antenna(s) which generates the highest available antenna
power and/or average total radiated power shall be assessed.
and described as follows, can be used to demonstrate
Four routes, as illustrated in Figure 1
compliance with this standard:
A Typical usage, installation and the physical characteristics of equipment make it
inherently compliant with the applicable EMF exposure levels such as those listed in the
bibliography. This low-power equipment includes unintentional (or non-intentional)
radiators, for example incandescent light bulbs and audio/visual (A/V) equipment,
information technology equipment (ITE) and multimedia equipment (MME) that does not
contain radio transmitters.
NOTE Equipment is described as A/V equipment, ITE or MME if its main use is playback/recording of music,
voice or images, or processing of digital information.
B The input power level to electrical or electronic components that are capable of radiating
electromagnetic energy in the relevant frequency range is so low that the available
antenna power and/or the average total radiated power cannot exceed the low-power
exclusion level defined in 4.2.
C The available antenna power and/or the average total radiated power are limited by
product standards for transmitters to levels below the low-power exclusion level defined
in 4.2.
D Measurements or calculations show t
