IEC 61511 Insights

What is IEC 61511?

IEC 61511 is an international standard that addresses the application of Safety Instrumented Systems (SIS) for the process industry sector. It specifies requirements for the specification, design, installation, operation, and maintenance of SIS, ensuring that process risks are reduced to tolerable levels. It is commonly used by process plants, oil and gas facilities, and chemical plants to implement safety functions that protect against hazardous events like explosions, leaks, and other critical failures.
