Functional Safety / SIL Certifications

IEC 61511/61508 describes four safety levels that describe the measures for handling risks from plants
or plant components.

The Safety Integrity Level (SIL) is a relative measure of the probability that the safety system can correctly provide the required safety functions for a given period of time.

The higher the safety integrity level (SIL), the greater the reduction of the risk.
