Anotation

IEC 62808:2015 establishes requirements for the design, analysis and qualification of isolation devices used to ensure electrical independence of redundant safety system circuits, or between safety and lower class circuits, as specified in IEC 60709. This standard includes guidance on the determination of the maximum credible fault that is applied to the isolation devices. The maximum credible fault can be used as a basis for the test levels used in testing based on other standards (e.g. IEC TS 61000-6-5 or IEC 62003). LIEC 62808:2015 etablit des exigences pour la conception, les analyses et la qualification des appareils disolement utilises pour garantir lindependance electriques entre les circuits des systemes de surete redondants ou entre les circuits des systemes de surete et des systemes dont la classe de surete est inferieure, comme specifie dans lIEC 60709. La presente norme comprend des recommandations portant sur la determination du defaut maximal previsible qui est pris en compte pour les appareils disolement. Le defaut maximal previsible peut etre utilise comme une base pour le niveau des essais definis a partir dautres normes (par exemple lIEC TS 61000-6-5 ou lIEC 62003).
