Grundlagen der funktionalen Sicherheit

The publication gives an overview of the main contents and structure of the IEC 61508-Standard for functional safety of safety related E/E/PE-Systems and . The most important definitions of the standard are explained as well as methods and measures for risk-determination, SIL-classification, avoidance of systematic failures, control of random hardware failures (failure rates), calculation of the safe failure fraction (SFF), probability of failures per hour (PFH), probability of failures on demand (PFD), diagnostic coverage (DC), hardware failure tolerance (HFT) and common-cause-failures (CC).
