Part 22: Equipment to be installed outdoors
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.
International Standard IEC 60950-22 has been prepared by IEC TC 108: Safety of electronic
equipment within the field of audio/video, information technology and communication
technology.
This second edition cancels and replaces the first edition published in 2005. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– more extensive requirements for battery ventilation.

FDIS Report on voting
108/615/FDIS 108/634/RVD
Full information on the voting for the approval of this 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.
This Part 22 of IEC 60950 is intended to be used with IEC 60950-1:2005. The subclauses of
IEC 60950-1 apply as far as reasonable. Where safety aspects are similar to those of Part 1
the relevant Part 1 clause or subclause is shown for reference in parentheses after the clause
or subclause title in Part 22. Where a requirement in Part 22 refers to a requirement or
criterion of Part 1, a specific reference to IEC 60950-1, is made.
A list of all parts in the IEC 60950 series, published under the general title Information
technology equipment – Safety, can be found on the IEC website.
In this standard, the following print types are used:
– requirements proper and normative annexes: roman type;
– compliance statements and test specifications: italic type;
– notes in the text and in tables: smaller roman type;
– terms that are defined on Clause 3 and in IEC 60950-1: SMALL CAPITALS.
The following differing practices of a less permanent nature exist in the countries indicated
below.
– 4.1: Outdoor equipment demand special design at temperatures down to –50 °C (Finland,
Norway, Sweden)
– 4.3: Rise of earth potential requirements (USA, Canada)
– 8.5.1: Enclosure types specifications (USA, Canada).
– D.4: In Canada and United States, IRM Immersion Oil No. 903 is accepted (USA, Canada).
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
This standard proposes safety requirements for information technology equipment intended to
be installed, when exposed wholly or partly, in a location where protection from the weather
and other outdoor influences such as rain, dust, etc. normally provided by a building or other
structure is limited or non-existent. There are many examples of information technology
equipment in use throughout the world that are housed in special ENCLOSURES located on
pavements, mounted on telecommunications poles and situated underground. Presently,
IEC 60950 has no requirements for such equipment and this proposal would rectify this
omission. The proposed requirements would not apply to portable or transportable equipment
that may be occasionally used outdoors, but are not intended to be installed in conditions of
inclement weather.
It is expected that IEC TC108 will continue to coordinate the output of its work with other
technical committees dealing with equipment installed outdoors, such as IEC TC70 (Degrees
of protection provided by enclosures, responsible for IEC 60529) and IEC TC 48 (Electrical
connectors and mechanical structures for electrical and electronic equipment).
Annex E describes the rationale behind the treatment of specific safety aspects in this
standard.
