This European Standard specifies the determination of whole-body and hand-arm vibration emissions at operator position(s) during testing of mobile machinery. The purpose of this European Standard is to assist technical standardization committees responsible for specific types of machinery in preparing vibration test codes to ensure that such vibration test codes - are as homogeneous as possible with each individual test code having the same basic structure; - are in full accordance with basic standards on measurement of vibration emission; - reflect the latest technical knowledge of methods of determining the vibration emission from the specific family of machinery under consideration; - provide manufacturers with a standardized method for the determination and declaration of the vibration emission value(s) of their machinery; - enable the user of the machinery or the member of an inspection body to compare the vibration emission values of different machinery and to verify the vibration emission values provided by the manufacturer. This European Standard provides requirements for the preparation of vibration test codes, including guidelines for the conditions under which the measurements shall be made (e.g. operating conditions). Information to be included in a typical vibration test code is summarized in Annex A. Vibration test codes based on this European Standard should define measuring procedures which provide accurate and reproducible results which are as far as possible in agreement with values measured under real working conditions. For determination of the magnitude of the vibration to be noted in the instruction handbook, this European Standard requires operating conditions enabling the determination of the 75-percentile of the vibration experienced at the operator's position during the mode of operation causing the highest vibration. This European Standard applies to sitting and standing positions. It is applicable to all mobile machinery producing periodic or random vibration with or without transients. Rotational vibration is not dealt with in this European Standard. This European Standard contains sufficient guidance for designing an appropriate test for machinery for which no vibration test codes exist. It can also be used for the determination of vibration emission values of individual machines. This European Standard does not present limits or recommended vibration values. In general, the emission values should not be used for assessment of the health risk. This European Standard does not give any guidance or recommendations for determination of human exposure to vibration and shock.
