WEARABLE ELECTRONIC DEVICES AND TECHNOLOGIES –

Part 406-1: Test method for measuring surface temperature of wrist-worn
wearable electronic devices while in contact with human skin

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.
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 some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 63203-406-1 has been prepared by technical committee 124: Wearable electronic devices
and technologies. It is an International Standard.
The text of this International Standard is based on the following documents:
Draft Report on voting
124/161/FDIS 124/168/RVD

Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.

WEARABLE ELECTRONIC DEVICES AND TECHNOLOGIES –

Part 406-1: Test method for measuring surface temperature of wrist-worn
wearable electronic devices while in contact with human skin



1 Scope
This part of IEC 63203 defines the terms, definitions, symbols, configurations, and test methods
to be used to specify the standard measurement conditions and methods for determining the
contact-surface temperature of wrist-worn wearable electronic devices intended to be worn
directly on a human wrist and that can be worn continuously during use. The conditions of the
test do not consider perfusion and results are therefore considered conservatively. The
temperature increase is induced by the thermal energy of wearable electronic devices during
operation. This document gives the general procedure for the test method applicable to various
wrist-worn wearable electronic devices for use by ordinary persons which in the context of this
document is a healthy human adult.
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.
IEC 62368-1:2018, Audio/video, information and communication technology equipment – Part 1:
Safety requirements
3 Terms and definitions
For the purpose 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 http://www.iso.org/obp
• IEC Electropedia: Available at http://www.electropedia.org/
3.1
ambient temperature
average temperature of air or another medium in the vicinity of a wearable electronic device
Note 1 to entry: During the measurement of the ambient temperature the measuring instrument/probe should be
shielded from draughts and radiant heating.
[SOURCE: IEC 60050-816:2004, 826-10-03, modified – In the definition, "the equipment" has
been replaced with "a wearable electronic device".]
