The standard system for SIL certification

The international standards for SIL certification started early and are relatively systematic, generally divided according to different industries. For example, IEC61511 for the process industry, IEC61513 for the nuclear power industry, ISO26262 for the automotive industry, IEC62061 for the robotics industry, EN50126 f……
