(Main)Safety of machinery - Functional safety of safety-related control systems
Safety of machinery - Functional safety of safety-related control systems
This International Standard specifies requirements and makes recommendations for the design, integration and validation of safety-related control systems (SCS) for machines. It is applicable to control systems used, either singly or in combination, to carry out safety functions on machines that are not portable by hand while working, including a group of machines working together in a co-ordinated manner. This document is a machinery sector specific standard within the framework of IEC 61508 (all parts). The design of complex programmable electronic subsystems or subsystem elements is not within the scope of this document. This is in the scope of IEC 61508 or standards linked to it; see Figure 1. NOTE 1 Elements such as systems on chip or microcontroller boards are considered complex programmable electronic subsystems. The main body of this sector standard specifies general requirements for the design, and verification of a safety-related control system intended to be used in high/continuous demand mode. This document: - is concerned only with functional safety requirements intended to reduce the risk of hazardous situations; - is restricted to risks arising directly from the hazards of the machine itself or from a group of machines working together in a co-ordinated manner; NOTE 2 Requirements to mitigate risks arising from other hazards are provided in relevant sector standards. For example, where a machine(s) is part of a process activity, additional information is available in IEC 61511. This document does not cover - electrical hazards arising from the electrical control equipment itself (e.g. electric shock - see IEC 60204-1); - other safety requirements necessary at the machine level such as safeguarding; - specific measures for security aspects - see IEC TR 63074. This document is not intended to limit or inhibit technological advancement. Figure 1 illustrates the scope of this document. [Figure 1]
Sicherheit von Maschinen - Funktionale Sicherheit sicherheitsbezogener Steuerungssysteme
Sécurité des machines - Sécurité fonctionnelle des systèmes de commande relatifs à la sécurité
L'IEC 62061:2021 spécifie les exigences et donne des recommandations pour la conception, l'intégration et la validation des systèmes de commande relatifs à la sécurité (SCS) pour les machines. Elle s'applique aux systèmes de commande utilisés, séparément ou en combinaison, pour assurer les fonctions de sécurité de machines qui ne sont pas portables à la main en fonctionnement, y compris un groupe de machines fonctionnant ensemble d'une manière coordonnée. Le présent document est spécifique au secteur des machines dans le cadre de l'IEC 61508 (toutes les parties). La conception de sous-systèmes ou d'éléments de sous-système électroniques programmables complexes ne relève pas du domaine d'application du présent document. Ces éléments relèvent du domaine d'application de l'IEC 61508 ou de normes qui lui sont associées. Le présent document: – se concerne que les exigences de sécurité fonctionnelle destinées à réduire le risque de situations dangereuses; – se limite aux risques résultant directement des phénomènes dangereux de la machine elle même ou d'un groupe de machines fonctionnant ensemble d'une manière coordonnée; Le présent document ne concerne pas – les phénomènes dangereux électriques provenant du matériel de commande électrique lui même (par exemple choc électrique – voir l'IEC 60204-1); – les autres exigences relatives à la sécurité nécessaires au niveau de la machine (la protection par protecteur, par exemple); – les mesures particulières pour les aspects liés à la sécurité – voir l'IEC TR 63074. Le présent document n'est pas destiné à limiter ou inhiber les progrès technologiques. L'IEC 62061:2021 annule et remplace la première édition parue en 2005, l’Amendement 1:2012 ainsi que l’Amendement 2:2015. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: – la structure a été modifiée et le contenu a été mis à jour pour refléter le processus de conception de la fonction de sécurité, – la norme a été étendue aux technologies non électriques, – définitions mises à jour pour être alignées sur l'IEC 61508-4, – plan de sécurité fonctionnelle introduit et gestion de configuration mise à jour (Article 4), – exigences relatives au paramétrage étendues (Article 6), – référence aux exigences relatives à la sécurité ajoutée (Paragraphe 6.8) – exigences relatives aux essais périodiques ajoutées (Paragraphe 6.9), – différentes améliorations et clarifications relatives aux architectures et aux calculs de fiabilité (Article 6 et Article 7), – décalage entre le "SILCL" et le "SIL maximal" d'un sous-système (Article 7), – cas d'utilisation pour les logiciels décrits, y compris les exigences (Article 8), – exigences relatives à l'indépendance des activités de vérification (Article 8) et de validation (Article 9) du logiciel ajoutées, – nouvelle annexe informative avec des exemples (Annex G), – nouvelles annexes informatives relatives aux valeurs MTTFD, aux diagnostics et aux méthodes de calcul des architectures (Annex C, Annex D et Annex H).
