Safety of machinery - Safety-related parts of control systems - Part 1: General principles for design (ISO 13849-1:2006)

This standard provides safety requirements and guidance on the principles for the design of safety-related parts of control systems (SRP/CS). For these parts it specifies characteristics and categories required for carrying out related safety functions. It applies to SRP/CSs, regardless of the type of technology and energy used (e.g. electrical, hydraulic, pneumatic, mechanical) for all kinds of machinery. It does not specify which safety functions and which categories shall be used in a particular case.
In the case of using electronic system(s), this standard is applicable if one or more of the following is satisfied:
1) the required performance level (PLr)is a or b, or
2) the safety function is carried out by hardware where the fault behaviour is clearly determined and assessable, or
3) the contribution of programmable electronic systems within the SRP/CS which carries out the safety function is low (e.g. for monitoring) and the  (PLr)is from a to d, or
4) the safety function is carried out by diverse programmable electronic systems  and the required performance level is from a to d. Depending on the application the diverse programmable electronic system consists of diverse application software and/or diverse operational systems and/or diverse hardware and the required performance level is from a to d, or
5) safety-related parts used (including the software) are designed to the requirements of appropriate standards.
NOTE 1   For the definition of required performance level see 3.24.
NOTE 2   The requirements provided in this standard for programmable electronic systems are compatible with the methodology for the design and development of safety-related electrical, electronic and programmable electronic control systems for machinery given in the horizontal application standard IEC 62061 (under preparation in IEC/TC44/WG7).

Sicherheit von Maschinen - Sicherheitsbezogene Teile von Steuerungen - Teil 1: Allgemeine Gestaltungsleitsätze (ISO 13849-1:2006)

Dieser Teil der ISO 13849 stellt Sicherheitsanforderungen und einen Leitfaden für die Prinzipien der Gestaltung und Integration sicherheitsbezogener Teile von Steuerungen (SRP/CS) bereit, einschließlich der Entwicklung von Software. Für diese Teile der SRP/CS werden Eigenschaften, einschließlich des Performance Levels, festgelegt, die zur Ausführung der entsprechenden Sicherheitsfunktionen erforderlich sind. Er ist anzuwenden auf SRP/CS aller Arten von Maschinen, ungeachtet der verwendeten Technologie und Energie (elektrisch, hydraulisch, pneumatisch, mechanisch usw.).
Er legt nicht fest, welche Sicherheitsfunktionen oder Performance Level für einen speziellen Fall verwendet werden.
Dieser Teil der ISO 13849 stellt spezielle Anforderungen für SRP/CS mit programmierbar elektronischen Systemen bereit.
Er stellt keine speziellen Anforderungen an den Entwurf von Produkten, die Teile von SRP/CS sind. Trotzdem können die angegebenen Prinzipien, wie Kategorien oder Performance Level, verwendet werden.
ANMERKUNG 1   Beispiele von Produkten, die Teile von SRP/CS sind: Relais, Magnetventile, Positionsschalter, PLC(en), Antriebssteuerungen, Zweihandschaltungen, druckempfindliche Schutzeinrichtungen. Für den Entwurf solcher Produkte ist es wichtig, sich auf spezielle anwendbare Internationale Normen zu beziehen, z. B. ISO 13851, ISO 13856-1 und ISO 13856-2.
ANMERKUNG 2   Für die Definition des erforderlichen Performance Levels, siehe 3.1.24.
ANMERKUNG 3   Die in diesem Teil der ISO 13849 bereitgestellten Anforderungen für programmierbare elektronische Systeme sind kompatibel mit der Methodik für Gestaltung und Entwicklung sicherheitsbezogener elektrischer, elektronischer und programmierbarer elektronischer Steuerungen für Maschinen in der IEC 62061.
ANMERKUNG 4   Für sicherheitsbezogene Embedded-Software in Komponenten mit PLr = e, siehe IEC 61508-3:1998, Abschnitt 7.
ANMERKUNG 5   Siehe auch Tabelle 1.

Sécurité des machines - Parties des systèmes de commande relatives à la sécurité - Partie 1: Principes généraux de conception (ISO 13849-1:2006)

La présente norme fournit des prescriptions de sécurité et des conseils relatifs aux principes de  conception des parties des systèmes de commande relatives à la sécurité (SRP/CS). Pour ces parties, elle spécifie les catégories et les caractéristiques requises pour réaliser ces fonctions de sécurité. Elle s'applique aux SRP/CS de tous les types de machines, indépendamment de la technologie et du type d'énergie utilisés (par exemple : électrique, hydraulique, pneumatique, mécanique). Elle ne spécifie pas quelles fonctions de sécurité et quelles catégories doivent être utilisées dans un cas particulier.
En cas d'utilisation de système(s) électronique(s), la présente norme s'applique si l'une ou plusieurs des conditions suivantes sont réalisées :
1) le niveau de performance requis (PLr) est a ou b ; ou
2) la fonction de sécurité est réalisée par du matériel dont le comportement en cas de défaut est clairement déterminé et appréciable ; ou
3) la contribution des systèmes électroniques programmables à la SRP/CS réalisant la fonction de sécurité est faible (par exemple pour la surveillance) et le PLr est compris entre a et d ; ou
4) la fonction de sécurité est réalisée par des systèmes électroniques programmables diversitaires et le niveau de performance requis est compris entre a et d. Selon l'application, le système électronique programmable diversitaire est constitué de logiciels applicatifs diversitaires et/ou de systèmes opérationnels diversitaires et/ou de matériels diversitaires et le niveau de performance requis est compris entre a et d ; ou
5) les parties relatives à la sécurité utilisées (y compris le logiciel) sont conçues conformément aux prescriptions des normes applicables.
NOTE 1   Pour la définition du niveau de performance requis, voir 3.24.
