CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes CEN/TR 15350:2006. The main technical changes compared to CEN/TR 15350

PD CEN/TR 15350:2013CEN/TR 15350:2013 (E) 4 Introduction This Technical Report provides information on how to assess the vibration exposure from hand-held power tools and hand-guided machines. The methods described use existing vibration emission values de

23、clared 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 also the d

24、eclared 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 found in li

25、terature 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 work situatio

26、n 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 which an em

27、ployee 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 correction fact

28、ors 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. PD CEN/TR 15350:2013CEN/TR 15350:2013 (E) 5 1 Scope This Technical Report gi

29、ves guidelines for estimating, assessing and documenting the daily vibration exposure due to the use of hand-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 serv

30、ices for the assessment of vibration exposure at the workplace and to national authorities and industrial organisations. 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 in

31、stead of measuring the vibration magnitudes at the specific workplaces, the methods in this Technical Report 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

32、/EC. It is important that the vibration values used in the exposure assessment are representative of those in 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

33、 calculation results do not help to decide whether or not the vibration exposure limit value or exposure action 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 off

34、ers a simple method for estimating the daily vibration exposure by means of a table which indicates the vibration 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

35、 gives guidance for manufacturers and suppliers of machinery concerning information that warns of risks from 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

36、 its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

38、finitions given in EN ISO 5349-2:2001 and the following apply. 3.1 user time daily duration of the work involving the use of the machinery, i.e. including the interruptions required by the work and the break periods directly related to the use Note 1 to entry: This is more likely to be reported by t

39、he operator than the exposure duration (see 3.2). 3.2 exposure duration T total duration the hand is in direct contact with the vibrating surface (handle, work piece, etc.) Note 1 to entry: The exposure duration is often confused with the user time when estimating the daily exposure duration T (see

40、Example in 7.2.2). PD CEN/TR 15350:2013CEN/TR 15350:2013 (E) 6 EXAMPLE The user time for mounting wheels on five automobiles is estimated by the operator at 1 h per day; but the exposure duration is just 5 cars x 4 lug nuts x 4 wheels x 2 loosening/tightening actions x 4 s which yields T = 0,18 h. T

41、he 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 be determined in time studies. Some indication is given in G.2. 3.4 equival

The total exposure duration T

43、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). If there is one operating mode only, then ahv,eq= ahv. 3.5 partial vibration exposure points PEindex describing the vibration exposure from a single machine

48、celeration value in metres per second squared (m/s2) as defined in EN ISO 5349-1. The vibration magnitude for a particular machine can be highly variable. For example, operators, different operating conditions and different inserted tools all influence the actual magnitude. The magnitude also often

49、varies over time. It is usually difficult or impossible to obtain a precise value or narrow value range, so an indication of the average value is all that can be expected. For exposure estimation, it is usually necessary to take into account the fact that values are obtained within a range of uncertainty (see Clause 6). 4.2 Sources of information Vibration magnitudes may be measured at the workplace by the employer, or on his behalf. However, this can be expensive and difficult and it is not alway
