Failure finding interval Interval it is considered safe to wait before performing failure-finding maintenance. The interval is calculated or estimated based on the desired availability and the frequency of failure of the protective device or system. When failure mode optimization requires Isograph Availability Workbench, this attribute is mapped to the inspection task’s PF interval property in AWB. See Also Useful Life Age at which there is a rapid increase in the conditional probability of failure. See Also PF interval The PF interval is the time between the point at which a potential failure becomes detectable and the point at which it degrades into a functional failure. When failure mode optimization requires Isograph Availability Workbench, this attribute is mapped to the inspection task’s PF interval property in AWB. See Also Modification type The modification type for the modification/redesign recommended task. Examples are Maintenance procedure, Training, and Physical. When failure mode optimization requires Isograph Availability Workbench, this attribute is mapped to the cause’s Redesign description property in AWB. See Also Frequency Frequency with which the recommended action needs to be performed. When failure mode optimization requires Isograph Availability Workbench, this attribute is mapped to the inspection task’s Interval property in AWB. See Also Technology PdM technology used in the performance of the action. See Also Operating condition Operating condition of the asset when the action is performed. See Also Maintenance group Group that will perform the action. See Also
