Safety integrity level sil
WebSafety Integrity Level (SIL) SILs are from IEC 62061 which previously only focused on electrical and electronic systems but the new 2024 revision is now applicable to all safety related control systems bringing it to be much closer in scope to ISO 13849-1. Similar to PLs, SILs are based on the probability of dangerous failures per hour (PFHd). WebUnderstanding the How Why and What of a Safety Integrity Level (SIL)
