EN IEC 61969-1:2020

Mechanical structures for electrical and electronic equipment - Outdoor enclosures - Part 1: Design guidelines

IEC 61969-1:2020 is available as IEC 61969-1:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61969-1:2020 contains design guidelines for outdoor enclosures 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. This third edition cancels and replaces the second edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - alignment with the content of ETSI EN 300 019 and IEC 60721 series latest editions, particularly with the actualization of climate conditions; - new requirements added to reflect market requirements on environmental issues; - improvement on terminology and overall editorial improvement.

Structures mécaniques pour équipement électrique et électronique - Enveloppes de plein air - Partie 1: Lignes directrices pour la conception

IEC 61969-1:2020 est disponible sous forme de IEC 61969-1:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 61969-1:2020 fournit des lignes directrices pour la conception des enveloppes de plein air et s’applique à une grande variété d’équipements mécaniques, électromécaniques et électroniques et à leur installation en configuration modulaire. Le présent document est destiné: - à fournir une vue d’ensemble des spécifications applicables aux enveloppes, portant essentiellement sur les exigences propres aux applications de plein air pour une utilisation à poste fixe à des emplacements non protégés contres les intempéries, et - à assurer l’intégrité du produit dans des conditions extérieures et à faciliter le choix du produit lors de l’approvisionnement en enveloppes de plein air auprès des différents vendeurs. Cette troisième édition annule et remplace la deuxième édition parue en 2011. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - alignement sur le contenu de l’édition la plus récente des séries ETSI EN 300 019 et IEC 60721, en particulier concernant l’actualisation des conditions climatiques; - ajout de nouvelles exigences pour refléter celles du marché relatives aux questions environnementales; - amélioration de la terminologie et modifications éditoriales générales.

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
