GUIDE FOR THE EVALUATION OF HUMAN EXPOSURE TO WHOLE-BODY VIBRATION. ADDENDUM 2: EVALUATION OF EXPOSURE TO WHOLE-BODY Z-AXIS VERTICAL VIBRATION IN THE FREQUENCY RANGE 0.1 TO 0.63 HZ

This addendum covers vibration transmitted to the body in the frequency range 0.1 to 0.63 hz. This addendum applies especially to discrete frequency and narrow band of vibration and provisionally to random and non-periodic vibrations within the specified frequency range. The boundaries defined in this addendum are intended to minimise the severe discomfort associated with motion sickness and allied symptoms. The "severe discomfort" boundary has some similarity to, but is not an extension of, the "exposure limit" (see ISO 2631) which is intended to protect against pain and permanent injury rather than temporary incapacity. Because of lack of data, it is not possible to recommend an extension of the fatigue-decreased proficiency boundary below 1 hz, but suggestions are made on the unwanted effects on activity due to inertial loading. Lack of data also confines the recommendations specifically to z-axis vibration only, applied to unadapted sitting or standing fit young men. The existence of measured levels exceeding the boundaries contained in this addendum should not be construed as implying that undesirable effects occur or will occur in random vibration environments where experience shows otherwise.
