19、nformative) Bibliography 8 O BSI 1997 COPYRIGHT European Committee for StandardizationLicensed by Information Handling ServicesIntroduction Information on vibration emission of vibrating machinery is needed by users, planners, manufacturers and authorities, for example to comply with the obligations
20、 described in the EU Machmery Directives 89/392/EEC and 9i/368/EEC. This information is required for comparing the vibration emissions from different products and for assessing the vibration against vibration requirements. In order for vibration emission values to be useful, uniform methods are nece
21、ssary for the following purposes: - measurement of the vibration values; - determination of the declared vibration emission value; - presentation of the declared vibration emission value; - verification of the declared vibration emission value. The statistical methods used for declaration and verifi
22、cation in this European Standard are equivalent to those used in acoustics (see EN 27574). NOTE. This note concerns German words for declaration and verification. 1 Scope This European Standard establishes the requirements for declaration and verification of vibration emission values. It applies to
23、hand-arm and whole-body vibration values achieved by measurements according to type-B and type-C standards. It: - gives guidance on the declaration of vibration emission values; - describes vibration and product information to be given in technical documents supplied to users by the manufacturer; -
24、specifies the method for venfymg the declared vibration emission values stated by the manufacturer. The values to be used for the declaration of vibration emission are r.m.s. values of weighted acceleration measured preferably according to a vibration test code (see 3.1.5). 2 Normative references “h

These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publi

28、ndard, the following definitions apply They are grouped in two categories: general definitions and vibration-related definitions. Defintions of statistical terms are to be found in annex k 3.1 General definitions 3.1.1 machinery An assembly of linked parts or components, at least one of which moves,
29、 with the appropriate actuators, control and power circuits etc., joined together for a specific application, in particular for the processing, treatment, moving or packaging of material. The term machinery also covem an assembly of machines which, in order to achieve the same end, are asranged and
30、controlled so that they function as an integrai whole. 3.1.2 family of machinery Machinery of similar design or type, intended to perform the same functions. 3.1.3 batch (lot) of machinery A number of units of machinery intended to perform the same function, produced in quantity, manufactured to the
31、 same technical specifications and characterized by the same declared vibration emission value. NOTE. The batch may be an entire production series or a portion thereof.

33、type of machinery It gives all the information necessary to efficiently carry out the determination of the vibration emission characteristics needed for declaration and verifcation according to this European Standard. It ensures compatibility and allows comparison of test results. 3.2 Vibration-rela
34、ted definitions 3.2.1 acceleration The r.m.s value of the vibration acceleration. 3.2.2 hand-arm weighted acceleration ah,w The acceleration at the measuring point determined by measurement using a weighting filter according to ENV 28041 or by calculation as specified in ENV 25349. It is expressed i
35、n dS2. 3.2.3 whole-body weighted acceleration The acceleration at the measuring point determined by measurement using weighting filters according to ENV 28041 and IS0 2631-1. It is expressed in m/s2. 3.2.4 measured vibration emission value a The value representing the measured vibration emission val
36、ue of a single machine or the mean value obtained from a reasonably big sample of a batch of machinery It is expressed in m/s2. The measured vibration emission value is not rounded. NOTE. The measured vibration emission value GI. can be either one of the weighted values according to 3.2.2 or 3.2.3.
37、3.2.6 uncertainty K The value representing the measurement uncertainty of the measured vibration emission value a, and also, in the case of batches, production variations of machinery It is expressed in m/s2. 3.2.6 declared vibration emission value a und K The measured vibration emission value a and
38、 its associated uncertainty K. The sum of a and K indicates the limit below which the vibration value of the single machine, andor a specified large proportion of the vibration values of the batch of the machines, are stated to lie when the machines are new. 3.2.7 vibration emission declaration The
39、information on vibration emission of a machine, given by the mufacturer or supplier in technical documents or other literature, concerning vibration emission values. The vibration emission declaration has the form of a dual-number value. Q,wx, %vy, a, and a, 4 Declaration of vibration emission value
40、s The declaration of the vibration emission values a and K of machinery is the sole responsibility of the manufacturer. The declared vibration emission values shall be determined for the machine in an operating mode according to the description in the relevant vibration test code. If no vibration te
41、st code exists the most representative operating mode should be used. Guidelines for determination of declared vibration emission values of machinery are given in annex B. The guidelines are made in such a fashion that the declared values can be verified according to the procedures of this European
42、Standard. NOTE. If data required for the determination of Kare unavailable from other standards applicable to the particular machine, guidance can be found in annex D. 5 Presentation of declared vibration emission values The presentation of declared vibration emission values according to this Europe
43、an Standard for machinery, shall, when given in technical documents, contain the following information: - identification of the product with sufficient detail to determine the applicability of the declared vibration emission values; - the words declared vibration emission value in accordance with EN
44、 12096 foliowed by the vibration emission due a and the uncertainty K, both in m/s2, for the operating mode described in the relevant vibration test code; - identification of the relevant type-C standard, or, if no type-C standard e or - in order to ver the decked value of a batch or production seri
45、es of machinew. Verification shall be effected by means of vibration measurements made according to the same vibration test code or basic measurement method, and under the same machinery operating mode (see 3.1.4) as that one to which the declared vibration emission values refer. The procedures give
46、n in 6.2 and 6.3 shall be used for verification under reproducibility conditions. NOTE. Reproducibility conditions exist when the measurements can be repeated with similar results of the inspecting laboratory and when there are no systematic deviations between the testing laboratory and other labora
47、tories testing the same object. When the declaration contajns only one value, the guidelines given in annex D can be used for estimating the uncertainty K. 6.2 Verification of a single machine If one machine is evaluated, the declared vibration emission value is verified if the resulting vibration e
48、mission value is less than or equal to the value of a + K as declared by the manufacturer. NOTE. The procedure for verifying the declared vibration emission value for a single machine conforms with that, one descibed in EN 275744 for noise. 6.3 Verification of a batch of machinery 6.3.1 General This
49、 procedure shall be used to venfy the declared vibration emission value of a batch (or of a production series) of machinery when more than one machine from a batch is available. For the purpose of this European Standard, a sample size of up to three machines is needed. NOTE. The procedure for verifying the declared vibration emission value for a batch conforms with that one described in EN 275744 for noise.
