IEC 60966-2-2:2024 is a blank detail specification that relates to flexible coaxial cable assemblies operating in the transverse electromagnetic mode (TEM). The creation of a uniform layout and style of detail specifications is determined by the use of a blank detail specification pro forma. The detail specification may be prepared by a national organization, a manufacturer or a user.

L’IEC 60966-2-2:2024 est une spécification particulière-cadre qui concerne les cordons coaxiaux souples qui fonctionnent en mode électromagnétique transverse (TEM, Transverse Electromagnetic Mode). La création d'une présentation et d'un modèle uniformes de spécifications particulières est déterminée par l'utilisation d'un modèle de spécification particulière-cadre. La…

IEC 60034-2-1:2024 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60034-2-1:2024 is intended to establish methods of determining efficiencies from tests, and also to specify…

IEC 60034-2-2:2024 applies to large rotating electrical machines and establishes additional methods of determining separate losses and to define an efficiency supplementing IEC 60034‑2‑1. These methods apply when full-load testing is not practical and results in a greater uncertainty. The specific methods described are: - Calibrated-machine method. - Retardation method. - Calorimetric method…

L'IEC 60034-2-2:2024 s'applique aux machines électriques tournantes de grande taille et établit des méthodes supplémentaires pour la détermination des pertes séparées et qui sont destinées à définir un rendement, en complément de l'IEC 60034‑2‑1. Ces méthodes s'appliquent lorsqu'un essai à pleine charge n'est pas possible ou qu'il présente une plus grande…

IEC 60669-2-4:2024 applies to manually operated general purpose isolating switches with a rated voltage not exceeding 440 V and a rated current not exceeding 125 A, intended for household and similar fixed electrical installations, either indoors or outdoors. This second edition cancels and replaces the first edition published in 2004. This edition constitutes a technical revision. This edition…

L’IEC 60669-2-4:2024 s’applique aux interrupteurs-sectionneurs pour usage général manœuvrés manuellement, de tension assignée ne dépassant pas 440 V et de courant assigné ne dépassant pas 125 A, destinés aux installations électriques fixes domestiques et analogues intérieures ou extérieures. Cette deuxième édition annule et remplace la première édition parue en 2004, dont elle constitue une…

IEC 60669-2-4:2024 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60669-2-4:2024 EXV includes the content of the references made to IEC 60669-1:2017. IEC 60669-2-4:2024 applies to manually operated general purpose…

IEC TS 62443-6-1:2024 specifies the evaluation methodology to support interested parties (e.g. during conformity assessment activities) to achieve repeatable and reproducible evaluation results against IEC 62443-2-4 requirements. This document is intended for first-party, second-party or third-party conformity assessment activity, for example by product suppliers, service providers, asset owners…
