IEC 61511 places an emphasis on the proper specification, design and integration of final elements, and doing these steps correctly is necessary to ensure a SIL capable system is deployed. As users collect more data through testing methods, they are discovering that final element assemblies are not always performing reliably throughout their mission time. Two observed failures are torque/force that is insufficient to move the valve to the safe state and mechanical failure of final element components from stress beyond the element’s ultimate strength. These failures modes are evidence that the current processes need to be enhanced. One proposed means of addressing these shortcomings is to assess not only the individual devices that make up the final element but also to assess the complete final element. This webinar will review the steps required to complete a final element assessment.
