The following standards use SIL as a measure of reliability and/or risk reduction.
ANSI/ISA S84 (Functional safety of safety instrumented systems for the process industry sector)
- IEC 61508 (Functional safety of electrical/electronic/programmable electronic safety related systems)
- IEC 61511 (Safety instrumented systems for the process industry sector)
- IEC 61513 (nuclear industry)
- IEC 62061 (safety of machinery)
- EN 50128 (railway applications – software for railway control and protection)
- EN 50129 (railway applications – safety related electronic systems for signalling)
- EN 50402 (fixed gas-detection systems)
- ISO 26262 (automotive industry)
The use of a SIL in specific safety standards may apply different number sequences or definitions to those in IEC EN 61508
