The methods described use existing vibration emission

26、 values declared for the machine of interest or information coming from other sources. It should be noted that vibration usually varies a lot over time, with different workstations and different operators. It is therefore not possible to get precise exposure figures from limited investigations. But

27、also the declared values need to be used with great care since they are measured for a limited number of defined work situations. The actual work situation for a specific operator, however, may be very different thus creating different vibration. On the other hand values from real work that can be f

28、ound in literature are only correct for the specific work situation and time when they were measured. The user of this Technical Report should be aware that the exposure to vibration does not only depend on the machine used but also to a large extent on things like quality of inserted tools, the wor

29、k situation and operator behaviour. These factors need to be taken into account to make an ideal assessment of vibration exposure. The daily vibration exposure to be assessed depends on both the average magnitude of vibration at the surface in contact with the hand and the total daily duration for w

30、hich an employee is in contact with that vibration. As there is a big difference between a rough estimation of the daily vibration exposure to identify workers at risk and the definition of the state of the art regarding machine vibration emission, vibration total values calculated by applying corre

31、ction factors are not suitable to determine the state of the art for machine categories. To define the state of the art a high level of accuracy is needed, which means that this can only be obtained by measurements in all three axes.

33、held power tools and hand-guided machines, according to the requirements of the European Physical Agents Directive (vibration) 2002/44/EC. This Technical Report is addressed to competent services for the assessment of vibration exposure at the workplace and to national authorities and industrial or

34、ganisations. It helps to establish documentation for specific machinery or work situations and can also be useful for employers. It follows the method of EN ISO 5349-1 and EN ISO 5349-2 but instead of measuring the vibration magnitudes at the specific workplaces, the methods in this Technical Report

35、 use existing vibration values from other sources of information including those provided by the manufacturers of the machinery according to the requirements of the Machinery Directive 2006/42/EC. It is important that the vibration values used in the exposure assessment are representative of those i

36、n the specific use of the machinery. Workplace measurements, however, are required if suitable data are not available to represent the vibration under the specific working conditions or if the calculation results do not help to decide whether or not the vibration exposure limit value or exposure act

37、ion value is likely to be exceeded. This Technical Report gives guidance on how to estimate the exposure duration and the daily vibration exposure A(8) as defined in EN ISO 5349-1. It also offers a simple method for estimating the daily vibration exposure by means of a table which indicates the vibr

38、ation exposure as a function of the equivalent vibration total value and the associated exposure duration. Both methods can be used even in cases of multiple exposures on the same day. Annex A gives guidance for manufacturers and suppliers of machinery concerning information that warns of risks from

39、 vibration, which should be reported to the customer. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest e

45、4 wheels x 2 loosening/tightening actions x 4 s which yields T = 0,18 h. The exposure proportion (see 3.3) is only 18 %. 3.3 exposure proportion exposure duration expressed as percentage of the user time Note 1 to entry: The exposure proportion varies depending on the machinery and its use. It can b

The total exposure duration T for a machine is the sum of all m individual exposure durations Tiwithin the entire work cycle considered (see Table G.1 and Example in 7.2.2).
