säkerhetssintegritetsnivå
Säkerhetssintegritetsnivå, often abbreviated as SIL, is a measure of risk reduction provided by a safety instrumented system (SIS). It quantifies the likelihood that a safety function will not perform its intended function when required. SIL is typically specified on a scale from 1 to 4, with SIL 4 representing the highest level of risk reduction and SIL 1 the lowest. A higher SIL requires a greater reduction in risk, meaning the system must be more reliable and have a lower probability of failure.
The SIL is determined through a risk assessment process that identifies potential hazards and evaluates the
The concept of SIL is crucial in industries where failures of safety systems can lead to severe
