<volt-mismatch>
The voltage mismatch describes the ability of a component, or a system, to accomplish its specified function in case of a voltage mismatch in the ground conduction or power supply. The voltage mismatch can be caused by an external connection of sensors or actuators to the ground conduction or to the power supply (e.g. use of the car body as ground conduction). A max. admissible voltage mismatch can be defined, for the ground connection as well as for the power supply, with the aid of the reference point.
The description of the voltage mismatch is valid for all electrical connections (there is no reference to any electrical connection). If there are different descriptions for some electrical connections, a further description of the voltage mismatch is defined for each difference (with reference to the concerned connection).
Besides the measuring voltage and the test duration, there can always be given additional specifications for each test, e.g. the test set-up.
