Anotation

IEC 60947-5-5:2026 This edition includes the following significant technical changes with respect to the previous edition: a) re-shaping the document with the clause numbers and names to be in line with other documents of the 60947 series; b) review of the test method to reasonably determine that the latch mechanism meets the requirements of the document; c) new Annex B for special requirements for illuminated push-button type emergency stop devices, including the reference to a function to distinguish between "active and inactive" by changing the colour of the push-button depending on the illumination. This part of IEC 60947-5 provides detailed specifications relating to the electrical and mechanical construction of emergency stop devices with mechanical latching function and to their testing. This document is applicable to electrical control circuit devices and switching elements which are used to initiate an emergency stop signal. Such devices can be provided with their own enclosure and will be installed according to the product documentation. This document does not apply to: – emergency stop devices for non-electrical control applications, for example hydraulic or pneumatic; – emergency stop devices without mechanical latching function. An emergency stop device conforming to this document can also be used as part of an emergency switching off means in compliance with IEC 60364-5-53. NOTE See also IEC 60204-1:2016 and IEC 60204-1:2016/AMD1:2021, 9.2.3.4. This document does not address specific requirements on acoustic noise as the noise emission of electrical emergency stop devices with mechanical latching function is not considered to be a relevant hazard. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision. IEC 60947-5-5:2026 Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) le document a ete restructure en salignant sur les numeros et intitules darticles et de paragraphes des autres documents de la serie IEC 60947; b) la methode dessai a ete revue afin de determiner de maniere raisonnable que le mecanisme de verrouillage respecte les exigences du document; c) la nouvelle Annexe B definit les exigences particulieres pour les appareils darret durgence a bouton-poussoir lumineux en faisant notamment reference a la fonction qui permet de distinguer les etats "actif" et "inactif" en faisant varier la couleur dillumination du bouton-poussoir. La presente partie de lIEC 60947-5 fournit des specifications detaillees concernant la construction electrique et mecanique des appareils darret durgence avec accrochage mecanique et leurs essais. Le present document sapplique aux appareils et elements de commutation pour circuits de commande electriques, qui sont utilises pour generer un signal darret durgence. Ces appareils peuvent etre equipes de leur propre enveloppe et sont installes conformement a la documentation du produit. Le present document ne sapplique pas: – appareils darret durgence pour applications de commande non electriques, par exemple hydrauliques ou, pneumatiques; – appareils darret durgence sans accrochage mecanique. Un appareil darret durgence conforme au present document peut egalement etre utilise dans le cadre dun moyen de coupure durgence conformement a lIEC 60364-5-53. NOTE Voir aussi le 9.2.3.4 de lIEC 60204-1:2016 et de lIEC 60204-1:2016/AMD1:2021. Le present document ne traite pas des exigences specifiques relatives au bruit acoustique, car lemission de bruit des appareils darret durgence electriques avec accrochage mecanique nest pas consideree comme constituant un danger pertinent. Cette seconde edition annule et remplace la premiere edition parue en 1997. Cette edition constitue une revision technique.
