"Surya, thanks for your questions. I checked with some friends who manage our
Fisher brand of valves & instruments.
They shared back, "Table 5 of IEC61508-1 (2010) provides guidelines for the
minimum levels of independence of those carrying out a functional safety
assessment (applying to overall safety lifecycle phases 9 and 10, including all
phases of E/E/PE system and software safety lifecycles). Please closely
evaluate 8.2.16 and Notes 1, 2, and 3, as well as 8.2.15, 8.2.18 of IEC61508-1
to help determine whether your organization is capable of conducting an
independent assessment. If you still have questions, please consult a third
party safety consultant who will be able to advise based on the details of your
specific organization and application.""
