Annotation of standard text IEC 60947-5-1-ed.5.0 :
IEC 60947-5-1:2024 applies to control circuit devices and switching elements intended for controlling, signalling, interlocking, etc., of switchgear and controlgear. It applies to control circuit devices having a rated voltage not exceeding 1 000 V AC (at a frequency not exceeding 1 000 Hz) or 600 V DC. This fifth edition cancels and replaces the fourth edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) update of the scope structure and exclusions; b) requirements for control circuits; c) update of the normal service conditions (e.g. shock and vibration); d) update of information and marking requirements including environmental information requirements referencing IEC TS 63058:2021; e) update of the constructional requirements and the corresponding tests considering safety aspects (e.g. artificial optical radiation, security aspects, limited energy source, stored charge energy circuit); f) update of the EMC requirements according to the generic documents; g) new requirements for reed contact magnetic switches in Annex D; h) requirements for class II circuit devices achieved by double or reinforced insulation in Annex F; i) update of pull-out tests in Annex G; j) information requirements for audible signalling device in Annex J; k) insertion of new Annex O. LIEC 60947-5-1:2024 sapplique aux appareils pour circuits de commande et aux elements de commutation destines a la commande, a la signalisation, au verrouillage, etc., de lappareillage. Elle sapplique aux appareils pour circuits de commande dont la tension assignee ne depasse pas 1 000 V en courant alternatif (a une frequence qui ne depasse pas 1 000 Hz) ou 600 V en courant continu. Cette cinquieme edition annule et remplace la quatrieme edition parue en 2016. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) mise a jour de la structure du domaine dapplication et des exclusions; b) exigences pour les circuits de commande; c) mise a jour des conditions normales demploi (chocs et vibrations, par exemple); d) mise a jour des exigences relatives aux informations et eu marquage, y compris les exigences concernant les informations relatives a lenvironnement qui font reference a lIEC TS 63058:2021; e) mise a jour des exigences de construction et des essais correspondants compte tenu des considerations de surete (par exemple rayonnement otique artificiel, aspects relatifs a la securite, source denergie limitee, circuit denergie de charge emmagasinee); f) mise a jour des exigences de CEM conformement aux documents generiques; g) nouvelles exigences pour les interrupteurs magnetiques a lames souples a lAnnexe D; h) exigences relatives aux appareils de classe II pour circuits respectees par une double isolation ou une isolation renforcee a lAnnexe F; i) mise a jour des essais de traction a lAnnexe G; j) exigences relatives aux informations concernant les dispositifs de signalisation sonore a lAnnexe J; k) insertion dune nouvelle Annexe O.
