• Unrevealed failures refer to the sort of failures that are detected only by inspection or testing. For instance, failures that occur during the standby mode of a system may remain undiscovered until there is a real demand of activity unless some inspection is carried out during the idle time. In this paper the maintenance of multi-component systems which may be either in operating condition or in the standby mode is studied. A less than perfect testing procedure to detect failures in the latter case is considered. We concentrate on the existence of an optimum policy weighing the cost incurred under this policy against the cost derived from an undetected failure.
