Describes the evaluation of human exposure to whole-body Z-axis vertical vibration in the frequency range 0.1 to 0.63 Hz, and applies especially to discrete-frequency and narrow-band vibration and provisionally to random or non-periodic vibrations within the specified frequency range. Identical with and reproduced from ISO 2631-3:1985.

This part of ISO 2631 covers vibration transmitted to the body in the frequency range 0,1 to 0,63 Hz. This part of IS 0 2631 applies especially to discrete-frequency and narrow-band vibration and provisionally to random or non- periodic vibrations within the specified frequency range.The boundaries defined in detail in 3.1 are intended to minimize 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 4.1.2 in ISO 2631/1) 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. Reference is also made by a "reduced comfort" boundary in 3.3.Lack of data also confines the recommendations specifically to z-axis vibration only, applied to unadapted sitting or standing fit young men. Tentative factors are suggested for some of the important variables outside these constraints (see 3.1.2).The existence of measured level exceeding the boundaries contained in this part of ISO 2631 should not be construed as implying that undesirable effects occur or will occur in random vibration environments where experience shows otherwise.
