IEC 62061 introduced, in the new edition, the important Failure Rate \u03bbNE, or No Effect Failure, that does not contribute to the SFF of the subsystem. DC, SFF, MTTFD, CCF are explained in detail. The importance of HFT (Hardware fault Tolerance) is highlighted and, linked to that, the Route 1H and the Proof Test concepts are presented."}
