Mechanical structures for electrical and electronic equipment - Outdoor enclosures - Part 1: Design guidelines (IEC 61969-1:2023)

This part of IEC 61969 contains design guidelines for outdoor enclosures for electrical and electronic equipment and is applicable over a wide field of mechanical, electromechanical and electronic equipment and its installation where a modular design is used.
The objectives of this document are:
- to provide an overview of specifications for enclosures focused on requirements for outdoor applications for stationary use at non-weather protected locations, and
- to achieve product integrity under outdoor conditions and to ease product selection for the sourcing of outdoor enclosures from different vendors.
These enclosures are considered to contain any equipment and provide protection for the outdoor installed facilities against unwanted environmental impacts. The installed equipment can be, but is not limited to, subracks or chassis according to IEC 60917 (all parts) or IEC 60297 (all parts). A typical outdoor enclosure is shown in Figure 1.

Mehanske strukture za električno in elektronsko opremo - Ohišja na prostem - 1. del: Smernice za projektiranje (IEC 61969-1:2023)

Ta del standarda IEC 61969 vsebuje smernice za projektiranje za ohišja električne in elektronske opreme na prostem in se uporablja za široko področje mehanske, elektromehanske in elektronske opreme ter njene namestitve, pri kateri se uporablja modularno projektiranje.
Namen tega dokumenta je:
– zagotoviti pregled specifikacij za ohišja, ki temeljijo na zahtevah za stacionarno uporabo na prostem na lokacijah, ki niso zaščitene pred vremenskimi vplivi; in
– doseči celovitost izdelka pod zunanjimi pogoji in olajšati izbiro ohišij za uporabo na prostem, ki jih ponujajo različni trgovci.
Ta ohišja so namenjena shranjevanju opreme in zagotavljanju zaščite pred neželenimi okoljskimi vlivi za opremo, ki je nameščena na prostem. Nameščena oprema lahko med drugim vključuje nosilce sklopov ali šasijo v skladu s standardom IEC 60917 (vsi deli) ali standardom IEC 60297 (vsi deli). Tipično ohišje za uporabo na prostem je prikazano na sliki 1.

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 61969-1 has been prepared by subcommittee 48D: Mechanical structures for electrical and
electronic equipment, of IEC technical committee 48: Electrical connectors and mechanical
structures for electrical and electronic equipment. It is an International Standard.
This fourth edition cancels and replaces the third edition published in 2020. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) added references to the environmental conditions defined by ETSI EN 300 019-1 and
IEC 60721-2 series;
b) reference made to the correct test specifications;
c) addition of laser hazard warning in case opto-electronic equipment is used.

54 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
55 services carried out by independent certification bodies.
56 6) All users should ensure that they have the latest edition of this publication.
57 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
58 members of its technical committees and IEC National Committees for any personal injury, property damage or
59 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

113 1 Scope
114 This part of IEC 61969 contains design guidelines for outdoor enclosures for electrical and
115 electronic equipment and is applicable over a wide field of mechanical, electromechanical and
116 electronic equipment and its installation where a modular design is used.
117 The objectives of this document are:
118 – to provide an overview of specifications for enclosures focused on requirements for outdoor
119 applications for stationary use at non-weather protected locations, and
120 – to achieve product integrity under outdoor conditions and to ease product selection for the
121 sourcing of outdoor enclosures from different vendors.
122 These enclosures are considered to contain any equipment and provide protection for the
123 outdoor installed facilities against unwanted environmental impacts. The installed equipment
124 can be, but is not limited to, subracks or chassis according to IEC 60917 (all parts) or
125 IEC 60297 (all parts). A typical outdoor enclosure is shown in Figure 1.
