During the test in vehicle the built-in component is exposed to interferences which are originated by switching known interference sources in the wiring harness. Following specifications can be made for the description of the test:
| | Test pulse
|
| | Severity level and corresponding peak voltage for the test pulse.
|
| | Test voltage
Vehicle network voltage applied during the test. It will only be defined if it deviates from the standard test voltage.
|
| | Minimum test amount
The minimum test amount is defined by the number of test pulses or by the duration of the test.
|
| | Interference source
The known component which generates the test pulse.
|
| | Operating state
The operating state defines the state of the system at which the test is performed. If the test is to be performed with various operating states, these can be grouped.
|
| | Function state
The assignment of a function state to the test is accomplished by a code letter (A...E).
|
| | Fault description
The failure mode of the system will be described in textual form, in addition to the function state (if it is not equal to A).
|
| | Additional specifications
Apart from the a.m. specifications, it is always possible to give additional specifications for a test. These include, e.g., a test temperature which differs from general specifications, the test set-up and further specifications which have not been defined yet.
