Abstract(in English) | One of the fundamental concepts of the standard, IEC 6150, is the target failure measures to be allocated to Electric/Electronic/Programmable Electronic Safety-Related Systems (SRSs), i.e., Safety Integrity Levels (SILs). In order to choose between the SILs, the standard classifies SRSs into two modes of operation. It was unclear which modes of operation should be applied to SRSs in the draft standard. The authors addressed this issue by proposing a new fault-tree model, deriving algorithm to quantify the model and to estimate the frequencies of harmful events. After that, the definitions for modes of operation were changed in the published standard. The present paper examines those new definitions in the view of estimation of harmful event frequencies. |
