Common mode failure
Common Mode Failure ( CMF ; German Representing error ) is a term from the European Standard EN ISO 12100-1 and referred to in the risk analysis the failure of several similar components or machinery, perform their failure to a loss event. These are errors that are not caused by a common cause. The term CMF must therefore be distinguished from a Common Cause Failure (failure due to a common cause).
Cascade faults must also be distinguished from this if one of the links in a cascaded (one behind the other) chain of components does not function properly and this fault affects the function of the entire chain.
An example of CMF are network disturbances, which include all influences (e.g. feedback) that emanate from the load currents on the way from the voltage source to the consumer in connection with the impedances in the network and affect the network voltage at the starting point.
