Safety of machinery - Interlocking devices associated with guards - Principles for design and selection (ISO/FDIS 14119:2024)
This document specifies principles for the design and selection (independent of the nature of the energy source) of interlocking devices associated with guards and provides guidance on measures to minimize the possibility of defeat of interlocking devices in a reasonably foreseeable manner.
This document covers principles for the design, selection and application of the following:
— parts of the guards which actuate interlocking devices;
— trapped key interlocking devices and systems for machinery applications.
NOTE ISO 14120 specifies general requirements for the design and construction of guards provided primarily to protect persons from mechanical hazards. The processing of the signal from the interlocking device to stop the machine and prevent unexpected start up is covered in ISO 14118, ISO 13849-1 and IEC 62061.
Sicherheit von Maschinen - Verriegelungseinrichtungen in Verbindung mit trennenden Schutzeinrichtungen - Leitsätze für Gestaltung und Auswahl (ISO/FDIS 14119:2024)
Diese Internationale Norm legt Leitlinien für die Gestaltung und Auswahl – unabhängig von der Art der Energiequelle – von Verriegelungseinrichtungen in Verbindung mit trennenden Schutzeinrichtungen fest und enthält eine Anleitung für Maßnahmen, mit denen die Möglichkeit des Umgehens von Verriegelungseinrichtungen in vernünftigerweise vorhersehbarer Art und Weise auf ein Mindestmaß verringert wird.
Diese Internationale Norm behandelt Teile von trennenden Schutzeinrichtungen, die Verriegelungseinrichtungen betätigen, und deckt Grundsätze für die Gestaltung, Auswahl und Anwendung von Verriegelungseinrichtungen mit Schlüsseltransfersystem sowie Systemen für Maschinenanwendungen ab, unabhängig von der Energieart, die für deren Steuerung genutzt wird oder die diese selbst steuern.
ANMERKUNG ISO 14120 legt allgemeine Anforderungen an die Gestaltung und die Konstruktion von trennenden Schutzeinrichtungen fest, die hauptsächlich dafür vorgesehen sind, Personen vor mechanischen Gefährdungen zu schützen. Die Verarbeitung des von der Verriegelungseinrichtung ausgehenden Signals zum Anhalten der Maschine und um deren unerwarteten Anlauf zu verhindern, wird in ISO 13849-1 oder IEC 62061:2015 behandelt.
Sécurité des machines - Dispositifs de verrouillage associés à des protecteurs - Principes de conception et de choix (ISO/FDIS 14119:2024)
Le présent document spécifie des principes de conception et de choix (indépendamment de la nature de la source d'énergie) des dispositifs de verrouillage associés à des protecteurs et fournit des recommandations concernant les mesures visant à minimiser la possibilité de neutralisation des dispositifs de verrouillage d'une manière raisonnablement prévisible.
Le présent document couvre les principes de conception, de choix et de fonction suivants:
— des composants constituant les protecteurs responsables de l'activation des dispositifs de verrouillage;
— des dispositifs et systèmes de verrouillage à clé captive pour l'application aux machines.
NOTE L'ISO 14120 spécifie les exigences générales relatives à la conception et à la construction des protecteurs principalement destinés à préserver les personnes des phénomènes dangereux mécaniques. Le traitement du signal issu du dispositif de verrouillage entraînant l'arrêt de la machine et empêchant toute mise en marche intempestive est couvert dans l'ISO 14118, l'ISO 13849-1 et l'IEC 62061.
