Safety of machinery - Safety-related parts of control systems - Part 2: Validation (ISO 13849-2:2003)
ISO 13849-2:2003 specifies the procedures and conditions to be followed for the validation by analysis and testing of:
the safety functions provided and
the category achieved
for the safety-related parts of the control system in compliance with EN 954-1 (ISO 13849-1), using the design rationale provided by the designer.
This International Standard does not give complete validation requirements for programmable electronic systems and therefore can require the use of other standards.
Sicherheit von Maschinen - Sicherheitsbezogene Teile von Steuerungen - Teil 2: Validierung (ISO 13849-2:2003)
Diese Europäische Norm legt die Vorgehensweisen und Bedingungen in Übereinstimmung mit EN 954-1 (ISO 13849-1) fest, die bei der Validierung durch Analyse und Prüfung zu befolgen sind, für:
- die vorgesehenen Sicherheitsfunktionen und
- die ausgeführten Kategorien
der sicherheitsbezogenen Teile von Steuerungen, bei Anwendung der durch den Konstrukteur vorgesehenen sinnvollen Gestaltung.
Diese Europäische Norm gibt keine vollständigen Validierungsanforderungen für programmierbare elektronische Systeme und kann deshalb die Anwendung anderer Normen erfordern.
ANMERKUNG CEN/TC 114/WG 6 schlägt vor, sich eingehender mit der Validierung von programmierbaren elektronischen Systemen bei der Erarbeitung der Änderung der EN 954-1 (ISO 13849-1) zu befassen. Eine Anwendungsnorm für Maschinen (Entwurf IEC 62061), der die IEC 61508 zu Grunde liegt, wird zurzeit erarbeitet. Die Anforderungen für programmierbare elektronische Systeme, einschließlich der damit verbundenen Software, sind in IEC 61508 enthalten.
Sécurité des machines - Parties des systèmes de commande relatifs à la sécurité - Partie 2: Validation (ISO 13849-2:2003)
L'ISO 13849-2:2003 spécifie les procédures et conditions à suivre pour la validation par analyse et par essais:
des fonctions de sécurité assurées, et
de la catégorie atteinte
par les parties de système de commande relatives à la sécurité en conformité avec l'EN 954-1 (ISO 13849-1), en utilisant le raisonnement de conception fourni par le concepteur.
La présente Norme internationale ne donne pas de prescriptions complètes de validation pour les systèmes électroniques programmables et peut par conséquent nécessiter l'utilisation d'autres normes.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13849-2 was prepared by the European Committee for Standardization (CEN) in collaboration with
Technical Committee ISO/TC 199, Safety of machinery, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
Throughout the text of this document, read “.this European Standard.” to mean “.this International
Standard.”.
ISO 13849 consists of the following parts, under the general title Safety of machinery — Safety-related parts
of control systems:
— Part 1: General principles for design
— Part 2: Validation
— Part 100: Guidelines for the use and application of ISO 13849-1
