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 document(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.
IEEE Standards documents are developed within IEEE Societies and Standards Coordinating Committees of the
IEEE Standards Association (IEEE SA) Standards Board. IEEE develops its standards through a consensus
development process, approved by the American National Standards Institute, which brings together volunteers
representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members
of IEEE and serve without compensation. While IEEE administers the process and establishes rules to promote
fairness in the consensus development process, IEEE does not independently evaluate, test, or verify the
accuracy of any of the information contained in its standards. Use of IEEE Standards documents is wholly
voluntary. IEEE documents are made available for use subject to important notices and legal disclaimers (see
http://standards.ieee.org/ipr/disclaimers.html for more information).
IEC collaborates closely with IEEE in accordance with conditions determined by agreement between the two
organizations. This Dual Logo International Standard was jointly developed by the IEC and IEEE under the terms
of that agreement.
2) The formal decisions 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. The formal decisions of IEEE on technical matters, once consensus within IEEE Societies
and Standards Coordinating Committees has been reached, is determined by a balanced ballot of materially
interested parties who indicate interest in reviewing the proposed standard. Final approval of the IEEE standards
document is given by the IEEE Standards Association (IEEE SA) Standards Board.
3) IEC/IEEE Publications have the form of recommendations for international use and are accepted by IEC National
Committees/IEEE Societies in that sense. While all reasonable efforts are made to ensure that the technical
content of IEC/IEEE Publications is accurate, IEC or IEEE 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
(including IEC/IEEE Publications) transparently to the maximum extent possible in their national and regional
publications. Any divergence between any IEC/IEEE Publication and the corresponding national or regional
publication shall be clearly indicated in the latter.
5) IEC and IEEE do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC and IEEE are 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 IEEE or their directors, employees, servants or agents including individual
experts and members of technical committees and IEC National Committees, or volunteers of IEEE Societies and
the Standards Coordinating Committees of the IEEE Standards Association (IEEE SA) Standards Board, 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/IEEE
Publication or any other IEC or IEEE 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 implementation of this IEC/IEEE Publication may require use of material
covered by patent rights. By publication of this standard, no position is taken with respect to the existence or
validity of any patent rights in connection therewith. IEC or IEEE shall not be held responsible for identifying
Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or
scope of Patent Claims or determining whether any licensing terms or conditions provided in connection with
submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discriminatory.
Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk
of infringement of such rights, is entirely their own responsibility.

INTRODUCTION
This document provides a method to evaluate the human exposure from wireless devices using
computational methods. This document was developed to provide procedures for the numerical
modelling and evaluation of such wireless devices operating close to the head, held in the hand
or in front of the face, mounted on the body or embedded in garments. It applies to individual
transmitters as well as to transmitters operating simultaneously with other transmitters within a
product. The choice of technique, i.e. FDTD or FEM, is optional but can be influenced by the
application. The advantages of computational procedures include the capability to provide
repeatable, non-intrusive methods for determining exposure in or near an object and without
the need for expensive hardware equipment. Device categories covered include but are not
limited to mobile telephones, radio transmitters in personal computers, desktop and laptop
devices, and multi-band and multi-antenna devices. This document specifies:
• requirements on the numerical software (Clause 5);
• model development and validation (Clause 7);
• power density computation and averaging (Clause 8);
• uncertainty evaluation (Clause 9);
• reporting requirements (Clause 10).
To develop this document, IEC Technical Committee 106 (TC 106) and IEEE International
Committee on Electromagnetic Safety (ICES), Technical Committee 34 (TC 34) Subcommittee
1 (SC 1) formed Joint Working Group 11 (JWG 11) on computational methods to assess the
power density of human exposure to radio frequency fields from wireless devices in close
proximity to the head and body.

ASSESSMENT OF POWER DENSITY OF HUMAN EXPOSURE TO RADIO
FREQUENCY FIELDS FROM WIRELESS DEVICES IN CLOSE PROXIMITY
TO THE HEAD AND BODY (FREQUENCY RANGE OF 6 GHz TO 300 GHz) –

Part 2: Computational procedure

1 Scope
This document specifies computational procedures for conservative and reproducible
computations of power density (PD) incident to a human head or body due to radio-
frequency (RF) electromagnetic field (EMF) transmitting devices. The computational
procedures described are finite-difference time-domain (FDTD) and finite element methods
(FEM), which are computational techniques that can be used to determine electromagnetic
quantities by solving Maxwell’s equations within a specified computational uncertainty. The
procedures specified here apply to exposure evaluations for a significant majority of the
population during the use of hand-held and body-worn RF transmitting devices. The methods
apply to devices that can feature single or multiple transmitters or antennas, and that can be
operated with their radiating part or parts at distances up to 200 mm from a human head or
body.
This document can be employed to determine conformity with any applicable maximum PD
requirements of different types of RF transmitting devices used in close proximity to the head
and body, including those combined with other RF transmitting or non-transmitting devices or
accessories (e.g. belt-clip), or embedded in garments. The overall applicable frequency range
of these protocols and procedures is from 6 GHz to 300 GHz.
The RF transmitting device categories covered in this document include but are not limited to
mobile telephones, radio transmitters in personal computers, desktop and laptop devices, and
multi-band and multi-antenna devices.
The procedures of this document do not apply to PD evaluation of electromagnetic fields emitted
or altered by devices or objects intended to be implanted in the body.
NOTE For the evaluation of the combined exposure from simultaneous transmitters operating on frequencies below
6 GHz, the relevant standards for SAR computation are IEC/IEEE 62704-1:2017 and IEC/IEEE 62704-4:2020.
