Abstract

An overview is provided of the concepts of risk and safety-integrity in relation to safety-related electrical/electronic/programmable electronic systems. The overview is an abridged version of Annex A of the emerging International Electrotechnical Commission (IEC) standard on functional safety of electrical/electronic/programm electronic systems. The authors have, however, deviated in a few instances from the strict wording of Annex A to more properly represent their own views. The concepts of risk, including tolerable risk, safety integrity, safety-related system, and system and software integrity levels, are discussed
