3 Management of Proof Testing
3.1
Human errors during proof testing may result in dangerous failures being
introduced or overlooked, and therefore may also result in SIF failures.
Management arrangements should therefore be in place to ensure proof testing is
completed correctly. These should include measures for ensuring adequate
management of competency for those managing, specifying, or undertaking proof
testing and consideration of the appropriate human factors.
[Relevant good practice BS EN 61511-1 clauses 5.2.2.2, 11.2.5, 11.2.6]
3.2
Arrangements for proof testing should be documented, and SIS maintenance,
inspection and proof test outcomes (before and after states), including unplanned
work should be recorded. The arrangements taken for proof testing should also be
reviewed on a regular basis in the light of operating experience and relevant
maintenance records and information.
