EN IEC 62368-1:2024

Audio/video, information and communication technology equipment - Part 1: Safety requirements

IEC 62368-1:2023 is available as IEC 62368-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62368-1:2023 is a product safety standard that classifies energy sources, prescribes safeguards against those energy sources, and provides guidance on the application of, and requirements for, those safeguards. The prescribed safeguards are intended to reduce the likelihood of pain, injury and, in the case of fire, property damage. The objective of the introduction is to help designers to understand the underlying principles of safety in order to design safe equipment. These principles are informative and not an alternative to the detailed requirements of this document.

Equipements des technologies de l'audio/vidéo, de l'information et de la communication - Partie 1: Exigences de sécurité

IEC 62368-1:2023 est disponible sous forme de IEC 62368-1:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 62368-1:2023 est une norme de sécurité des produits qui classe les sources d’énergie, prescrit des mesures de protection contre ces sources d’énergie et fournit des lignes directrices sur l’application et les exigences de ces garanties. Les mesures de protection prescrites visent à réduire la probabilité de douleur, de blessure et, en cas d’incendie, de dommages matériels. L’objectif de l’introduction est d’aider les concepteurs à comprendre les principes sous-jacents de la sécurité afin de concevoir des équipements sûrs. Ces principes sont instructifs et ne constituent pas une alternative aux exigences détaillées du présent document.
