Annotation of standard text IEC 60947-5-8-ed.2.0 :

IEC 60947-5-8:2020 specifies requirements for three-position enabling switches. These switches are used as components of enabling devices to provide signals that, - when activated, allow machine operation to be initiated by a separate start control, and - when de-activated, -- initiate a stop function, and -- prevent initiation of machine operation. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - due to the increasing range of useful applications of three-position enabling switches, note of scope, operational characteristics and tests are reviewed; - figures for example of devices incorporating enabling switch are added in Annex A; - new Annex B for procedure to determine reliability data for the switch used in functional safety applications is added. LIEC 60947-5-8:2020 specifie les exigences pour les interrupteurs de commande de validation a trois positions. Ces interrupteurs sont utilises comme composants dans les appareils de commande de validation pour fournir des signaux qui: - lorsqu’ils sont actives, permettent la mise en marche de la machine par une commande separee de demarrage; et - lorsqu’ils sont desactives: -- initient une fonction d’arret; et -- evitent la mise en marche de la machine. Cette deuxieme edition annule et remplace la premiere edition parue en 2006. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - en raison du nombre croissant d’applications utiles possibles avec les interrupteurs de commande de validation a trois positions, le domaine d’application, les caracteristiques de fonctionnement et les essais sont revus; - des figures representant des exemples d’appareils incorporant un interrupteur de commande de validation sont ajoutees dans l’Annexe A; - une nouvelle Annexe B est ajoutee, incluant une procedure visant a determiner des donnees de fiabilite pour l’interrupteur utilise dans des applications de securite fonctionnelle.
