IEC 61078:2016 PDF

Scope: This International Standard describes: the requirements to apply when reliability block diagrams (RBDs) are used in dependability analysis; the procedures for modelling the dependability of a system with reliability block diagrams; how to use RBDs for qualitative and quantitative analysis; the procedures for using the RBD model to calculate availability, failure frequency and reliability measures for different types of systems with constant (or time dependent) probabilities of blocks success/failure, and for non-repaired blocks or repaired blocks; some theoretical aspects and limitations in performing calculations for availability, failure frequency and reliability measures; the relationships with fault tree analysis (see IEC 61025 [1]) and Markov techniques (see IEC 61165 [2]).
