Test Policy

set of procedures describing the various test operations (frequencies and procedures) scheduled to

reach the safety requirements of a given safety system

Note 1 to entry: The test policy should be thoroughly analysed and modelled to produce relevant probabilistic results.

Note 2 to entry: The forecasted probabilistic results established at the design stage are no longer valid if the test

policy which has been considered is not thoroughly applied in operation.
