<short-circuit-res>
The short-circuit strength describes the function state of the system in case of a clamp being held to ground or supply voltage thus producing a short-circuit. The short-circuit strength will be defined generally for all interfaces. Furthermore, depart from this specification the short-circuit strength can be defined for each connection regarding the description of interfaces.
The description of the short-circuit strength 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 short-circuit strength is defined for each difference (with reference to the concerned connection).
The MSR group defined the following description of the short-circuit strength:
