The work of preparing International Standards is normal
24、ly carried out through ISO technical committees. Each member body 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
25、 work. ISO collaborates closely with the International Electrotechnical 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 technica
26、l committees are circulated to the member bodies for voting. Publication 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.
27、ISO shall not be held responsible for identifying any or all such 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 can
28、cels and replaces ISO 5349:1986, of which it constitutes a technical 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
29、 with the greatest frequency-weighted root-mean-square acceleration. 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 char
30、acteristics of some power tool types are not dominated by a single 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 to
31、tal value of up to 1,7 times (typically between 1,2 and 1,5 times) 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 greates
32、t single-axis value is available, the vibration total value shall 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
33、 used a reference duration of 4 h. The change to the more conventional 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
34、reference duration is purely a matter of convention and does not 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 frequen
35、cies below 16 Hz and 6 dB per octave at higher frequencies and applied 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 W h . Band-limiting filters are also defined with cut-off f
36、requencies of 6,3 Hz and 1 250 Hz. The one-third-octave band weighting factors, also given in annex A, differ slightly from those in the previous version in that they describe the W h curve with band-limiting included.EN ISO 5349-1:2001(E)v The guidance in annex C on the relationship between vibrati
37、on 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. Compared to the previous version, daily vibr
38、ation 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 vibration total value. International Standar
39、d 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 A forms a normative part of this part of
40、 ISO 5349. Annexes B to F are for information only.EN ISO 5349-1:2001(E) vi Introduction Intensive vibration can be transmitted to the hands and arms of operators from vibrating tools, vibrating machinery or vibrating workpieces. Such situations occur, for example, when a person handles tools such a
41、s pneumatic, electric, hydraulic or internal combustion engine-driven chain saws, percussive tools or grinders. Depending on the type and place of work, 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 bo
42、dy parts and the perceived vibration are frequently a source of discomfort and possibly reduced proficiency. Continued, habitual use of many vibrating power tools has been found to be connected with various patterns of diseases affecting the blood vessels, nerves, bones, joints, muscles or connectiv
43、e tissues of the hand and forearm. The vibration exposures required to cause these disorders are not known precisely, neither with respect to vibration magnitude and frequency spectrum, nor with respect to daily and cumulative exposure duration. The guidance given in this part of ISO 5349 is derived
44、 from limited quantitative data available from both practical experience and laboratory experimentation concerning human response to hand-transmitted vibration, and on limited information regarding current exposure conditions. It is thus difficult to propose a comprehensive method for the evaluation
45、 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
46、 vibration-related health effects. It does not define safe exposure ranges in which vibration diseases cannot occur. The use of this part of ISO 5349 will contribute to the gathering of consistent data in order to improve occupational safety. In particular, it is hoped that such data will serve to e
47、xtend the present knowledge of dose-effect relationships. This part of ISO 5349 specifies the general requirements for the measurement and evaluation of human exposure to hand-transmitted vibration. It is supplemented by the information given in ISO 5349-2, which gives practical guidance for the imp
48、lementation of appropriate measurement and evaluation techniques at the workplace. Instrumentation to be used for measurements made in accordance with ISO 5349 is fully specified in ISO 8041. Annex A contains definitions for the frequency weighting W h and for band-limiting filters, required for measurement of frequency-weighted acceleration in accordance with ISO 5349. Annex B contains information on the health effects of hand-transmitted vibr
