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
