We have a situation where a proof test coverage of 95% on the final element part of a particular SIF is being claimed. The final element part consist of a solenoid valve and separate actuator and valve. Tight shut off is not necessary. Is this credible? H

This proof test coverage can be realistic if the test consists of more than just a full stroke (this is what the equipment database in exSILentia assumed). For example a leak test at operating conditions could be done in addition to the full stroke at operating conditions. This can yield a pretty high coverage factor and would support 95%. In this case I would recommend to include in the report that the customer is responsible for proving the effectiveness of their proof test.
