- Fault (technology)
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 1037Cof the United States, the term "fault" has the following meanings:
#An accidental condition that causes a
functional unitto 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.
