Limites d'utilisation des normes EN 61508 - EN 61511. Retour d'expérience d'un organisme de certification

Abstract : Safety functional standards and in particular the standards IEC 61508/61511 introduce an assessment of the dangerous failure probability on demand in complement of the traditional deterministic analysis. The application of these standards on various equipments and systems made it possible to highlight difficulties relating to the concepts calculated thus to the associated mathematical tools. Comparison of various mathematical models highlights that the use of Markov graphs can lead to approximate results for partially reparable equipments. The article will try to bring brief replies to these difficulties while being based on the experiment of INERIS in the assessment and the certification of instrumented safety material and systems.
