During a recent exida webinar we received the following question:
We tend to see more failures with actuated valves, than what manufacturers published failure rates would indicate! Any reason?
There are several reasons. Some manufacturers publish data based on field return data where they classify failures caused by customers…
In this blog series, I will cover the emerging trends in the valve assembly market, how these trends relate to the IEC 61511 requirements, and what's in a final element. When you look at the different devices that go into some of these safety systems, the final element becomes…
In Part 1, I covered the emerging trends in the valve assembly market, how these trends relate to IEC 61511 requirements, and the anatomy of final elements.
Now let’s discuss why we need to show requirements traceability down through the design of the safety instrumented function and then…
www.SILSafeData.com is a complimentary resource that contains the upper and lower bounds failure rates for many categories of automation equipment, as well as the methodology used by exida to derive the numbers.
Many of you have asked how to…
