27、opy, (c) BSI EN ISO 5349-1:2001(E) iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body
28、 interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotec
29、hnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publ
30、ication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 5349 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such
31、 patent rights. International Standard ISO 5349-1 was prepared by Technical Committee ISO/TC 108, Mechanical vibration and shock, Subcommittee SC 4, Human exposure to mechanical vibration and shock. This first edition of ISO 5349-1 cancels and replaces ISO 5349:1986, of which it constitutes a techni
32、cal revision. It is, in most respects, compatible with its predecessor, but differs from it technically in several important respects. In the previous version, the evaluation of vibration exposure was based on the directional component with the greatest frequency-weighted root-mean-square accelerati
33、on. In the present version, the evaluation is based on the “vibration total value”, i.e. the root-sum-of-squares of the three frequency-weighted root-mean-square component values. This change recognizes the fact that the vibration characteristics of some power tool types are not dominated by a singl
34、e directional component. Vibration exposures based on the root-sum-of-squares method will have values greater than those reported for a single direction of vibration. Measurement of vibration in three axes will result in a vibration total value of up to 1,7 times (typically between 1,2 and 1,5 times
35、) the magnitude of the greatest component. For data obtained in accordance with ISO 5349:1986, the vibration total value can be calculated from the three component values as shown in 4.5 of this part of ISO 5349. Where only the greatest single-axis value is available, the vibration total value shall
36、 be estimated from this value using a suitable multiplying factor as discussed in 4.5. The daily vibration exposure in accordance with this part of ISO 5349 is based on the 8-h energy-equivalent acceleration value. The previous version used a reference duration of 4 h. The change to the more convent
37、ional 8-h reference duration brings the evaluation of vibration exposure into line with the “time-weighted average” procedures commonly used for the evaluation of human exposures to noise and to chemical substances. The use of the 8-h reference duration is purely a matter of convention and does not
38、imply that a “typical” daily exposure duration is 8 h. Conversion of 4-h equivalent magnitudes to 8-h values is achieved easily, by applying a multiplying factor of 0,7. The frequency weighting previously had a slope of zero at frequencies below 16 Hz and 6 dB per octave at higher frequencies and ap
39、plied over the frequency range covered by the octave bands from 8 Hz to 1 000 Hz. It is now defined mathematically in annex A as a realizable filter characteristic, designated Wh. Band-limiting filters are also defined with cut-off frequencies of 6,3 Hz and 1 250 Hz. The one-third-octave band weight
40、ing factors, also given in annex A, differ slightly from those in the previous version in that they describe the Whcurve with band-limiting included.

41、ex C on the relationship between vibration exposure and the development of vascular symptoms, is broadly compatible with that in annex A of the previous version, but is restricted to consideration of a prevalence of 10 % in order to limit the potential for inappropriate use of the relationship. Comp
42、ared to the previous version, daily vibration exposures are now expressed as 8-h energy-equivalent values and the values quoted have been multiplied by a factor of 1,4 to estimate the increase resulting from the change from evaluation using the greatest single-axis value to evaluation using the vibr
43、ation total value. International Standard ISO 5349 consists of the following parts, under the general title Mechanical vibration Measurement and evaluation of human exposure to hand-transmitted vibration: Part 1: General requirements Part 2: Practical guidance for measurement at the workplace Annex
44、A forms a normative part of this part of ISO 5349. Annexes B to F are for information only. Licensed Copy: sheffieldun sheffieldun, na, Sat Nov 18 02:12:36 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN ISO 5349-1:2001(E) vi Introduction Intensive vibration can be transmitted to the hands and arms of
45、 operators from vibrating tools, vibrating machinery or vibrating workpieces. Such situations occur, for example, when a person handles tools such as pneumatic, electric, hydraulic or internal combustion engine-driven chain saws, percussive tools or grinders. Depending on the type and place of work,
46、 vibration can enter one arm only, or both arms simultaneously, and may be transmitted through the hand and arm to the shoulder. The vibration of body parts and the perceived vibration are frequently a source of discomfort and possibly reduced proficiency. Continued, habitual use of many vibrating p
47、ower tools has been found to be connected with various patterns of diseases affecting the blood vessels, nerves, bones, joints, muscles or connective tissues of the hand and forearm. The vibration exposures required to cause these disorders are not known precisely, neither with respect to vibration
48、magnitude and frequency spectrum, nor with respect to daily and cumulative exposure duration. The guidance given in this part of ISO 5349 is derived from limited quantitative data available from both practical experience and laboratory experimentation concerning human response to hand-transmitted vi
49、bration, and on limited information regarding current exposure conditions. It is thus difficult to propose a comprehensive method for the evaluation of vibration exposure. However, the use of the information given in this part of ISO 5349 should protect the majority of workers against serious health impairment associated with hand-transmitted vibration. It may also assist in the development of new hand-operated power tools to reduce the risk of vibration-related health effects. It does not define safe exposure ranges in which vibration diseases cannot occ
