Evaluation of whole-body vibration exposure experienced by operators of a downkoad wheel loader according to ISO and ISO Magnitude-dependence of equivalent comfort contours for fore-and-aft, Michael J.

Figure 2 depicts the comparison of the exposures in different lines. Similar results were found based on the data from the previous axis studies. Vibration exposure can occur at work, commuting between home and work, and in leisure activities. Any form of transportation will expose humans to some degree of vibration. Exposure to vibration can cause health problems, but more likely comfort problems. Health problems are normally related to back pain. Exposure boundaries or limits are not included and the concept of "fatigue-decreased proficiency" due to vibration exposure has been deleted.

In spite of these substantial changes, improvements and refinements in this part of ISO , the majority of reports or research studies indicate that the guidance and exposure boundaries recommended in ISO were safe and preventive of undesired effects.

This revision of ISO should not affect the integrity and continuity of existing databases and should support the collection of better data as the basis for the various dose-effect relationships. This part of ISO is concerned with whole-body vibration and excludes hazardous effects of vibration transmitted directly to the limbs e. Vehicles air, land and water , machinery for example, those used in industry and agriculture and industrial activities such as piling and blasting , expose people to periodic, random and transient mechanical vibration which can interfere with comfort, activities and health.

This part of ISO does not contain vibration exposure limits. However, evaluation methods have been defined so that they may be used as the basis for limits which may be prepared separately. It contains methods for the evaluation of vibration containing occasional high peak values having high crest factors. Three annexes provide current information on the possible effects of vibration on health annex B , comfort and perception annex C and on the incidence of motion sickness annex D.

This guidance is intended to take into account all the available data and to satisfy the need for recommendations which are simple and suitable for general application. The guidance is given in numerical terms to avoid ambiguity and to encourage precise measurements. However, when using these recommendations it is important to bear in mind the restrictions placed on their application.

More information may be obtained from the scientific literature, a part of which is listed in annex E. This part of ISO does not cover the potential effects of intense vibration on human performance and task capability since such guidance depends critically on ergonomic details related to the operator, the situation and the task design. Vibration is often complex, contains many frequencies, occurs in several directions and changes over time. The effects of vibration may be manifold.

Exposure to whole-body vibration causes a complex distribution of oscillatory motions and forces within the body. There can be large variations between subjects with respect to biological effects. Whole-body vibration may cause sensations e. The presence of oscillatory force with little motion may cause similar effects. It indicates the principal factors that combine to determine the degree to which a vibration exposure will be acceptable. Informative annexes indicate current opinion and provide guidance on the possible effects of vibration on health, comfort and perception and motion sickness.

Although the potential effects on human performance are not covered, most of the guidance on whole-body vibration measurement also applies to this area. This part of ISO also defines the principles of preferred methods of mounting transducers for determining human exposure.

It does not apply to the evaluation of extreme-magnitude single shocks such as occur in vehicle accidents. This part of ISO is applicable to motions transmitted to the human body as a whole through the supporting surfaces: the feet of a standing person, the buttocks, back and feet of a seated person or the supporting area of a recumbent person. This type of vibration is found in vehicles, in machinery, in buildings and in the vicinity of working machinery.

At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
