The sled test procedure described in this International Standard simulates low-speed rear-end impact resulting in a velocity change of the struck vehicle of 15 km/h. Its main purpose is the evaluation of the whiplash associated disorders due to seat occupant interactions with seat systems during the loading phase under standard conditions.
Seat-belts shall be used unless it is proven that they do not affect the occupant response.
The occupant protection potential of seat systems in other collision situations (e.g. higher velocity
change/vehicle accelerations possibly resulting in large deformation of the seat back) is not covered by this International Standard.
