IEC TR 63491:2025 This document has been prepared to provide guidance to end users for the selection, use and maintenance of electrical arc flash personal protective equipment (PPE).

IEC TR 63162:2025, which is a Technical Specification, provides failure rates at reference conditions for electric components, considering reference conditions defined in IEC 61709. Reference conditions are useful since they provide a known standard basis from which failure rates can be modified to account for differences in environment from the environments taken as reference conditions. To…

IEC 61097-7:2025 specifies the minimum performance requirements, technical characteristics and test methods with required test results for VHF radio installations capable of voice communication and digital selective calling as required by chapter IV of the International Convention for Safety of Life at Sea (SOLAS). This document incorporates the applicable part of the performance standards…

IEC 61097-9:2025 specifies the minimum operational and performance requirements and test methods with required test results for transmitters and receivers capable of voice communication and digital selective calling for the GMDSS operating in either the medium frequency band only or in medium and high frequency bands allocated in the ITU Radio Regulations to the Maritime Mobile Service, as…

Le présent document spécifie les caractéristiques des écrous hauts hexagonaux autofreinés (tout métal) à fente(s), en acier et en acier inoxydable, à filetage métrique à pas gros M5 à M39, et de grades A et B.
