Fault

In document ISO/CD 10303-226, a fault is defined as an abnormal condition or defect at the component, equipment, or sub-system level which may lead to a failure. According to the Federal Standard 1037C of the United States, the term fault has the following meanings: ⁕An accidental condition that causes a functional unit to fail to perform its required function. ⁕A defect that causes a reproducible or catastrophic malfunction. A malfunction is considered reproducible if it occurs consistently under the same circumstances. ⁕In power systems, an unintentional short-circuit, or partial short-circuit, between energized conductors or between an energized conductor and ground. A distinction can be made between symmetric and asymmetric faults. Failures in hardware can be caused by random faults or systematic faults, but failures in software are always systematic.
