INTERNATIONAL ELECTROTECHNICAL COMMISSION
____________
Wearable electronic devices and technologies -
Part 101-1: Terminology
FOREWORD
0.1 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 (here after 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.
0.2 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.
0.3 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.
0.4 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.
0.5 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.
0.6 All users should ensure that they have the latest edition of this publication.
0.7 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.
0.8 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.
0.9 IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights
in respect thereof. As of the date of publication of this document, IEC [had/had not] received notice of (a)
patent(s), which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the pat ent database available at
https://patents.iec.ch. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 63203-101-1 has been prepared by TC 124: Wearable electronic devices and technologies.
