3.1 EVDR event video data recorder
system that stores vehicle video data of the accident on an electronic recording medium before, during, and after collision accident events with other vehicles, with passers-by and with any other objects
Note 1 to entry: This note applies to the French language only.
3.2 event data
information recorded by the EVDR to facilitate analysis of accident scenarios in the case of collision accident events with other vehicles, pedestrians or objects
3.3 vehicle dynamics data
information on a vehicle’s dynamic behaviour such as acceleration, angular velocity, and physical quantities related to collision
3.4 integrity verification value
information used to detect doctoring and/or deletion of event data
4 Abbreviated terms

5 General requirements for tests
5.1 Test environment
The test environment of the event video data recorder shall be maintained at (23 ± 5) °C.
5.2 Simulation of accident events
5.2.1 General
Acceleration-generating equipment is used to generate the required acceleration for the simulation of a road accident event.
5.2.2 Simulation device
The acceleration-generating equipment shall be able to maintain 3 g for at least 50 ms. Peak acceleration error shall be within 1 0% of each of the absolute values of 0,5 g, 1 g, 1 ,5 g, and 2 g. The equipment also shall be able to generate a triangular waveform with a peak greater than 2 g.
The triangular waveform generated by the acceleration generating equipment for the simulation of a single or multiple accident event is illustrated in Figure 1 . Here, g i is the peak acceleration value applied to the EVDR under test. The peak acceleration shall be applied for at least 50 ms during the period of t 2 , and the acceleration and deceleration period, t 1 , shall be less than 1 0 s.EN IEC 63005-2 pdf download.
