47 FOREWORD
48 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
49 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
50 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
51 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
52 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
53 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
54 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
55 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
56 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
57 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
58 consensus of opinion on the relevant subjects since each technical committee has representation from all
59 interested IEC National Committees.
60 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
61 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
62 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
63 misinterpretation by any end user.
64 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
65 transparently to the maximum extent possible in their national and regional publications. Any divergence between
66 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
67 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
68 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
69 services carried out by independent certification bodies.
70 6) All users should ensure that they have the latest edition of this publication.
71 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
72 members of its technical committees and IEC National Committees for any personal injury, property damage or
73 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
74 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
75 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
76 indispensable for the correct application of this publication.
77 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
78 rights. IEC shall not be held responsible for identifying any or all such patent rights.
79 IEC 61969-3 has been prepared by subcommittee 48D: Mechanical structures for electrical and
80 electronic equipment, of IEC technical committee 48: Electrical connectors and mechanical
81 structures for electrical and electronic equipment. It is an International Standard.
82 This fourth edition cancels and replaces the third edition published in 2020. This edition
83 constitutes a technical revision.
84 This edition includes the following significant technical changes with respect to the previous
85 edition:
86 a) alignment with the content of ETSI EN 300 019 and IEC 60721 series latest editions,
87 particularly with the actualization of climate conditions;
88 b) rational for the selected operating conditions from IEC 60721-3-4 are added;
89 c) tests are grouped according to the classification of conditions in IEC 60721-3-4;
90 d) test severities for vibration and shock tests are aligned with ETSI EN 300 019-2-4;
91 e) addition of pass/fail criteria for each test.

113 INTRODUCTION
114 The products covered by IEC 61969 (all parts) are empty enclosures for outdoor locations, to
115 be equipped with application-specific combinations of electrical and electronic equipment, and
116 to be used at non-weather protected locations above ground.
117 IEC 61969 (all parts) consists of:
118 – a design guidelines general part (IEC 61969-1);
119 – a coordination dimensions standard (IEC 61969-2);
120 – an environmental requirements and tests, safety aspects standard (IEC 61969-3).
121 This document provides basic environmental requirements and tests, as well as safety aspects,
122 to be used for outdoor enclosures in absence of local regulatory documents, or of application-
123 specific environmental test requirements.
124 This document provides manufacturers and users of generic outdoor enclosures with minimum
125 performance compliance criteria. The thermal management solution depends on the specific
126 environment of the outdoor enclosure.
127 Since forced air heat dissipation and acoustic noise are closely related, noise limitations are
128 typically defined by local regulatory documents.
129 It is responsibility of the outdoor enclosure vendor to provide a solution for thermal management
130 within the local regulatory noise limitations.
