SINTEF is proud to present a new reliability data handbook, the 2021 edition of the PDS data handbook. The handbook is the ideal companion when performing reliability analysis of safety systems and is especially suited for analyses of safety integrity level (SIL) according to IEC 61508 and IEC 61511. The failure rates are established based on comprehensive operational experience and the detailing and assessment of the data have been significantly improved.
The handbook provides reliability data based on field feedback for safety equipment and includes detailed data dossiers for input devices (sensors, transmitters, detectors, etc.), control logic solvers (electronics) and final elements (valves, dampers, pumps, etc.). The data dossiers comprise recommended values for dangerous undetected failure rates, dangerous detected failure rates, safe failure rates, safe failure fraction (SFF), diagnostic coverage (DC), and information about the data sources.
Considerable effort has been made to ensure that the data are credible, traceable, documented and justified, in line with requirements in the IEC 61508 and IEC 61511 standards. The data have been subject to extensive quality assurance, where equipment experts and operational personnel have gone through and classified some thirty thousand maintenance notifications and work orders manually. This represents one of the broadest and best documented data bases for safety equipment, worldwide.
