43.2. Reliability Assessment

43.2.1. Component Failure Rates

An essential part of the design of reliable instrumentation and control systems is a regular assessment of reliability as the design proceeds. The design can then be guided towards the realization of the target MTBF as the finer details are decided and refined where necessary. If reliability assessment is delayed until the design is almost completed there is a danger that the calculated MTBF will be so wide of the target that much design work has to be scrapped and work restarted almost from the beginning.
In the preliminary design phase only an estimation of component numbers will be available and an approximation to the expected MTBF is all that can be computed. As the design proceeds ...
