SIS are instrumented systems that provide a significant level of risk reduction against accident hazards. An SIS is 6151 of a separate and independent combination of sensors, logic solvers, final elements, and support systems that are designed and managed to achieve a specified safety integrity level SIL. Safety instrumented systems for the sb industry sector Functional safety for the process industry and IEC Field data are collected through operational and mechanical integrity program activities to assess actual SIS performance.
The faster, easier way to work with standards. The process industry sector includes many types of manufacturing processes, such as refineries, petrochemical, chemical, pharmaceutical, pulp and paper, and power. Please help improve this article by introducing citations to additional sources. The content of these national publications is identical to that of IEC They typically consist of sensors and logic functions that detect a dangerous condition and final elements, such as valves, that are manipulated to achieve a safe state.

The essential roles of the various personnel assigned responsibility for the SIS should be defined and procedures developed, as necessary, to support the consistent execution of their responsibilities. It defines the safety lifecycle and describes how functional safety should be managed throughout that lifecycle.
