Safety integrity level (SIL) is defined as a relative levels of risk-reduction provided by a safety function or to specify a target level of risk reduction. In simple terms SIL is a measurement of performance required for a safety instrumented function (SIF).. The requirements for a given SIL are not consistent among all of the functional safety standards.
