1 Scope Replacement: This part of IEC 61558 deals with the safety of auto-transformers for general applications and power supply units incorporating auto-transformers for general applications. Transformers incorporating electronic circuits are also covered by this document. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here onward, the…

1 Domaine d’application 1.1 Inclusions Cette norme s’applique à la conception, à l’installation, au fonctionnement, à l’entretien et aux essais des groupes électrogènes et l’équipement connexe dont le rôle est d’assurer l’alimentation électrique de secours des charges électriques : a) dans des bâtiments ou des installations en cas de panne de l’alimentation normale, lorsqu’une alimentation…

This document specifies requirements for defining structure and content for library objects to support project inception, brief, design, tendering, construction, operations, use and demolition, supporting the development of information throughout the process, in connection with building information modelling (BIM) and the organization of the objects into libraries. This document does the…

L’IEC 60939-3:2024 couvre les filtres passifs utilisés pour atténuer les signaux aux fréquences radioélectriques indésirables (par exemple, le bruit ou le brouillage) générés par des sources électromagnétiques. Les filtres à voie unique et à voies multiples à l’intérieur d’une enveloppe, ou montés sur une carte de circuit imprimé qui forme une entité compacte, font partie du domaine d’application…

IEC 60079-11:2023 (EN) specifies the construction and testing of intrinsically safe apparatus intended for use in explosive atmospheres, and for associated apparatus which is intended for connection to intrinsically safe circuits which enter such atmospheres. This Type of Protection is applicable to electrical equipment in which the electrical circuits themselves are incapable of causing…
