The last edit to this post was made by The one on 2026-1-12 09:13. The criteria for classifying systems from SIL1 to SIL4 are primarily based on the international standard IEC 61508 (a general foundational standard applicable to electrical/electronic/programmable electronic safety-related systems), as well as its derived standards such as IEC 62061 (mechanical safety), ISO 26262 (automotive), and IEC 61511 (process industry). The core purpose of these levels is to quantify the risk reduction capability required for security-related systems. The higher the level, the greater the reliability required of the system to carry out its safety functions in the event of a hazard, and the more severe the associated risks.
