Determine Safety Integrity Levels (SIL) For Process Applications
WebThis concept of measuring SIF safety via risk reduction is called the SIL of the SIF and is measured by four order‐of‐magnitude levels í through ð with ð being the level of highest safety. The SIL assigned to a SIF is determined by the many requirements of IEC 61511 and IEC 61508. If the SIF experiences a demand frequently, faster than ...
