Annotation of standard text ČSN EN 61078-ed.2 (010677):

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) and Markov techniques (see IEC 61165)
