INTRODUCTION European Vibration and Noise The driver-perceived noise and hand/arm and whole body vibration levels of this machinery is measured per prEN 15997. The operating conditions of the machinery during testing: The vehicles were in like-new condition. The environment was controlled as indicated by the test procedure(s). The uncertainty of vibration exposure measurement is dependent on many factors, including:
Instrument and calibration uncertainty Variations in the machine such as wear of components Variation of machine operators such as experience or physique Ability of the worker to reproduce typical work during measurements Environmental factors such as ambient noise or temperature 7
