Instruments and Transmitters - SIS Instrumentation Common Cause Failure Details

In this video, you will learn about the instruments and transmitters common cause failure details.

Common Cause Failure (CCF) includes events that multiple components failure, affecting one or more SIS within a limited time interval.

The following definition of CCF has been used during operational reviews. “Components/items within the same component group that fail due to the same root cause within a specified time”.

Fraction of CCF experienced in Operations is higher than what is typically assumed in reliability calculations.
