12、tical with ISO 5008:1979 “Agricultural wheeled tractors and field machinery Measurement of whole-body vibration of the operator”, incorporating the erratum dated 1 June 1980, prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, of the International Organiza
13、tion for Standardization (ISO). Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is esp
14、ecially drawn to the following. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be read as “Briti
15、sh Standard”. Cross-references. There are no corresponding British Standards for the following international publications referred to in the text: IEC Publication 225:1966, ISO 2041:1975, ISO 2631:1978 and ISO/TR 5007. The technical committee has reviewed the provisions of these international public
16、ations and has decided that they are acceptable for use in conjunction with this standard. Related British Standards for IEC Publication 225:1966, ISO 2041:1975 and ISO 2631:1978 are BS 2475:1964 “Octave and one third octave band-pass filters”, BS 3015:1976 “Glossary of terms relating to mechanical
17、vibration and shock” and DD 32:1974 “Guide to the evaluation of human exposure to whole-body vibration” respectively. Since ISO/TR 5007 has now been published footnote 1) to clause 2 is no longer appropriate. The reference to ISO/TR 5007 in the note to clause 1 is of an informative nature only and t
18、he lack of an equivalent British Standard at present does not, therefore, affect the validity of this standard. However, it is intended that ISO/TR 5007 will be implemented as a British Standard in due course. NOTETextual error. When incorporating the erratum dated 1 June 1980, the following error w
19、as noticed. It has been corrected in this British Standard and has been reported to ISO/TC 23 in a proposal to amend the text of the International Standard. In paragraph 1 of 8.1, “track wheel setting” has been deleted and replaced by “wheel track setting”. A British Standard does not purport to inc
20、lude all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, page
21、s i and ii, pages 1 to 12, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated.

22、+00:00 2006, Uncontrolled Copy, (c) BSI BS 6055:1981 BSI 12-19991 0 Introduction The specification of instruments, measurement site characteristics and frequency analysis of weighting allows the measurements to be made and reported with an acceptable precision. The vibration is evaluated in accordan
23、ce with ISO 2631. The procedure includes means of weighting the vibration level at different frequencies to take account of agreed approximations to the frequency sensitivity of the human operator. 1 Scope and field of application This International Standard specifies methods for measuring and repor
24、ting the whole-body vibration to which the operator of an agricultural wheeled tractor or other field machine is exposed. The operating conditions of the machine and the ordinates of optional artificial test tracks are also included. This International Standard applies when measurements are made und
