Explanations to the Data Sheet The data sheet is divided in 4 areas: Common technical description of the set of components/component (blue) Failure rate (light green) Specification of architecture of the set of components/component (light orange) Verification of SIL capability (examples) (grey) General description of the Part / Component: Information on the set of components/component, type of component and component designator Manufacturer information Component type (Type A or Type B) acc. IEC 61508-2/7.4.4.1.2 und 7.4.4.1.3) Mode of operation of the set of components/component (acc. IEC 61508-1) Description of the safety function of the set of components/component Description of the safe state of the set of components/component Failure Rates The failure rates and failure rate distribution are the results of the reliability calculation of the set of components/component and the Failure Modes Effects and Diagnostic Analysis (FMEDA). The failure rates can be used for further quantitative analysis of the set of components/component as pfd/pfh-calculation, Markov-Analysis, Fault Tree Analysis, and due to this for a quantitative evaluation of SIL-capability of the set of components/component. Based on the failure rate distribution the Safe Failure Fraction (SFF) is calculated according the formula SFF [%] = ( S + DD) / ( S + DD + DU) Failure rates are calculated in acc. with NSWC-06 LE10. Specification of Component Architecture The architecture of the set of components/component is described by following parameters: Structure/architecture (single-channel, multi-channel expressed by 1oo1, 1oo2, 2oo3, etc.) Hardware-Fault-Tolerance (HFT) (number of failures acceptable without dispatch on the safety function of the set of components/component) Mean Time to Repair (MTTR): time to repair the set of components/component in case of failure Diagnostic Coverage: The diagnostic coverage is resulting from the diagnostic structure/diagnostic measures for the set of components/component in case of application of automatic diagnosis (e.g. partial stroke test). The diagnostic coverage is considered in the FMEDA and the quantitative results of the analysis (see failure rates) Verification of SIL-capability (examples) The SIL capability of the set of components/component is of major interest for the user. Therefore with respect to default values and basic qualitative and quantitative preconditions for the set of components/component a verification of the product capability for use in safety loops is calculated for some examples of proof test intervals. In case of deviation of the application specific values from the used default values an application specific evaluation is required. The verification consists of two steps: Step (1) = f{pfd; proof test interval}: quantitative verification by calculation of the pfd-value depending from the defined Proof Test Interval (6 months, 1 year, 2 years, 3 years, 5 years) Step (2) = f{HFT; component type; SFF}: qualitative verification based on the architectural information of the set of components/component The final achievable SIL is the minimum resulting SIL-value of step (1) and step (2): MIN {(1) ; (2)}. Caution: For a complete SIL-verification of a set of components/component additional measure to this quantitative analysis are required (methods and techniques used for the overall life cycle of the set of components/component). For proven-in use components a proven-in-use-assessment is possible. B130395_V10_SIL-Datenblatt_Polna_BR99 Seite 2 von 2 INGENIEURBÜRO URBAN – Dipl.-Ing. J. Urban Öffentl. Bestellung u.
