INTERNET OF THINGS (IoT) –
VOCABULARY
FOREWORD

1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical

Commission) form the specialized system for worldwide standardization. National bodies that are members of

ISO or IEC participate in the development of International Standards through technical committees established

by the respective organization to deal with particular fields of technical activity. ISO and IEC technical

committees collaborate in fields of mutual interest. Other international organizations, governmental and non-

governmental, in liaison with ISO and IEC, also take part in the work.

2) The formal decisions or agreements of IEC and ISO 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 and ISO National bodies.

3) IEC and ISO documents have the form of recommendations for international use and are accepted by IEC and

ISO National bodies in that sense. While all reasonable efforts are made to ensure that the technical content of

IEC and ISO documents is accurate, IEC and ISO 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 and ISO National bodies undertake to apply IEC and

ISO documents transparently to the maximum extent possible in their national and regional publications. Any

divergence between any IEC and ISO document and the corresponding national or regional publication shall be

clearly indicated in the latter.

5) IEC and ISO do not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC and ISO marks of conformity. IEC and ISO 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 document.

7) No liability shall attach to IEC and ISO or their directors, employees, servants or agents including individual

experts and members of its technical committees and IEC and ISO National bodies 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 ISO/IEC document or any

other IEC and ISO documents.

8) Attention is drawn to the Normative references cited in this document. Use of the referenced publications is

indispensable for the correct application of this document.

9) Attention is drawn to the possibility that some of the elements of this ISO/IEC document may be the subject of

patent rights. IEC and ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO/IEC 20924 has been prepared by subcommittee 41: Internet of

Things and related technologies, of ISO/IEC joint technical committee 1: Information

technology.

This second edition cancels and replaces the first edition published in 2018. This edition

constitutes a technical revision.

This edition includes the following technical changes with respect to the previous edition:

a) addition of new terms (safety, wearable device, data acquisition functional system,

transport interoperability, etc) which are used in other ISO/IEC IoT related standards;

b) update of some definitions (data, data store, discovery service, etc.) to align with current

usage in other IoT standards.
The text of this International Standard is based on the following documents:
FDIS Report on voting
JTC1-SC41/195/FDIS JTC1-SC41/209/RVD

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
