What is IEC61511?

IEC 61511 is an international standard that addresses the application of Safety Instrumented Systems (SIS) for the process industry sector. It defines requirements for the specification, design, installation, operation, and maintenance of SIS, ensuring safety integrity levels (SIL) are achieved to mitigate process hazards and reduce risk. It is commonly used to ensure that safety systems in chemical plants, oil refineries, and other process industry facilities function reliably and predictably in the event of a hazardous situation.

IEC61508 is the base standard for functional safety of electrical/electronic/programmable electronic (E/E/PE) safety-related systems. IEC61511 is an application-specific standard derived from IEC61508, specifically for the process industry sector. Therefore, IEC61508 is strongly complementary as it provides the framework upon which IEC61511 is built.
