Information technology equipment - Safety - Part 22: Equipment to be installed outdoors

Abstract

IEC 60950-22:2016 is available as IEC 60950-22:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60950-22:2016 applies to information technology equipment intended to be installed in an outdoor location. The requirements for outdoor equipment also apply, where relevant, to outdoor enclosures suitable for direct installation in the field and supplied for housing information technology equipment to be installed in an outdoor location. Each installation may have particular requirements. Some examples are given in 4.2. In addition, requirements for protection of the outdoor equipment against the effects of direct lightning strikes are not covered by the standard. For information on this subject, see IEC 62305-1. 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. Key words: Outdoor Equipment, Outdoor Locations, Outdoor Enclosure

This publication is to be read in conjunction with IEC 60950-1:2005.

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)
