Semiconductor devices - Mechanical and climatic test methods - Part 34-1: Power cycling test for pow...
IEC 60749-34-1:2025 describes a test method that is used to determine the capability of power semiconductor modules to withstand thermal and mechanical stress resulting from cycling the power dissipation of the internal semiconductors and the internal connectors. It is based on IEC 60749-34, but is developed specifically for power semiconductor module products, including insulated-gate bipolar…
Dispositifs à semiconducteurs - Méthodes d’essais mécaniques et climatiques - Partie 34-1: Essai de ...
L’IEC 60749-34-1:2025 décrit une méthode d’essai utilisée pour déterminer la capacité des modules de puissance à semiconducteurs à résister aux contraintes thermiques et mécaniques du fait du cyclage de la dissipation de puissance des semiconducteurs internes et des connecteurs internes. Elle est basée sur l’IEC 60749‑34, mais est développée spécifiquement pour les modules de puissance à…
Explosive atmospheres - Part 18: Equipment protection by encapsulation "m"
IEC 60079-18:2025 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60079-18:2025 edition 5.0 and the previous IEC 60079-18:2014+AMD1:2017 CSV edition 4.1. Furthermore, comments from IEC TC 31 experts are provided to explain the reasons of the most relevant changes, or to clarify…
Guidance and plan to develop smart energy ontologies
IEC SRD 63417:2025 provides guidance and a plan to develop smart energy ontologies and other domain-based ontologies within smart energy to achieve semantic interoperability through various standards, generic and specific ontologies projects. This includes but is not limited to the following.
• Assessment of a selection of existing ontologies for the purpose of smart energy applications:
