Vibration tests were performed for full suspension seats according to standard 781764/EEC. The tests include a test for determining the damping characteristics in the resonance range and a test for tractor seats in accordance with their intended use. In the former, the ratio of the rms values of the vibration acceleration on the seat surface to those at the seat attachment is measured. In the latter, the rms values of the weighted seat vibration acceleration for both the light driver and the heavy driver are measured.
