19、Page 3 EN 12096 : 1997 BSI 1997 Introduction Information on vibration emission of vibrating machinery is needed by users, planners, manufacturers and authorities, for example to comply with the obligations described in the EU Machinery Directives 89/392/EEC and 91/368/EEC. This information is requir

20、ed 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 necessary for the following purposes: measurement of the vibration values; determination of the de

21、clared vibration emission value; presentation of the declared vibration emission value; verification of the declared vibration emission value. The statistical methods used for declaration and verification in this European Standard are equivalent to those used in acoustics (see EN 27574). NOTE. This

22、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 handarm and whole-body vibration values achieved by measurements according to type-B and type-C standa

23、rds. 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; specifies the method for verifying the declared vibration emission values stated by the manufacturer. The val

24、ues 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 This European Standard incorporates by dated or undated reference, provisions from other publications. These

25、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 publications apply to this European Standard only when incorporated in it by amendment or revision. Fore undated

26、 references, the latest edition of the publication referred to applies. ENV 25349 Mechanical vibration Guidelines for the measurement and the assessment of human exposure to hand-transmitted vibration (ISO 5349 : 1986) ENV 28041 Human response to vibration Measuring instrumentation (ISO 8041 : 1990)

27、 ISO 2631-1 Mechanical vibration and shock Evaluation of human exposure to whole-body vibration Part 1: General requirements 3 Definitions and symbols For the purposes of this European Standard, the following definitions apply. They are grouped in two categories: general definitions and vibration-re

28、lated definitions. Definitions of statistical terms are to be found in annex A. 3.1 General definitions 3.1.1 machinery An assembly of linked parts or components, at least one of which moves, with the appropriate actuators, control and power circuits etc., joined together for a specific application,

29、 in particular for the processing, treatment, moving or packaging of material. The term machinery also covers an assembly of machines which, in order to achieve the same end, are arranged and controlled so that they function as an integral whole. 3.1.2 family of machinery Machinery of similar design

30、 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 same technical specifications and characterized by the same declared vibration emission value. NOTE. The ba

31、tch may be an entire production series or a portion thereof.Page 4 EN 12096 : 1997 BSI 1997 3.1.4 operating mode A condition in which the machinery is performing its intended function, which may be artificially simulated, as specified in a relevant standard. 3.1.5 vibration test code A type-C standa

32、rd related to a specified family or sub-family or type of machinery. It gives all the information necessary to efficiently carry out the determination of the vibration emission characteristics needed for declaration and verification according to this European Standard. It ensures compatibility and a

33、llows comparison of test results. 3.2 Vibration-related definitions 3.2.1 acceleration The r.m.s value of the vibration acceleration. 3.2.2 handarm weighted acceleration a h,w The acceleration at the measuring point determined by measurement using a weighting filter according to ENV 28041 or by calc

34、ulation as specified in ENV 25349. It is expressed in m/s 2 . 3.2.3 whole-body weighted acceleration a wx , a wy , a wz and a w The acceleration at the measuring point determined by measurement using weighting filters according to ENV 28041 and ISO 2631-1. It is expressed in m/s 2 . 3.2.4 measured v

35、ibration emission value a The value representing the measured vibration emission value of a single machine or the mean value obtained from a reasonably big sample of a batch of machinery. It is expressed in m/s 2 . The measured vibration emission value is not rounded. NOTE. The measured vibration em

36、ission value a can be either one of the weighted values according to 3.2.2 or 3.2.3. 3.2.5 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/s 2 . 3.2

37、.6 declared vibration emission value a and K The measured vibration emission value a and its associated uncertainty K. The sum of a and K indicates the limit below which the vibration value of the single machine, and/or a specified large proportion of the vibration values of the batch of the machine

38、s, are stated to lie when the machines are new. 3.2.7 vibration emission declaration The information on vibration emission of a machine, given by the manufacturer or supplier in technical documents or other literature, concerning vibration emission values. The vibration emission declaration has the

39、form of a dual-number value. 4 Declaration of vibration emission values 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 t

40、he description in the relevant vibration test code. If no vibration test 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 declare

41、d values can be verified according to the procedures of this European Standard. NOTE. If data required for the determination of K are unavailable from other standards applicable to the particular machine, guidance can be found in annex D. 5 Presentation of declared vibration emission values The pres

42、entation of declared vibration emission values according to this European 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

43、; the words declared vibration emission value in accordance with EN 12096 followed by the vibration emission value a and the uncertainty K, both in m/s 2 , for the operating mode described in the relevant vibration test code; identification of the relevant type-C standard, or, if no type-C standard

44、exists; identification of the applied operating mode and the relevant type-B standard. The value of the measured vibration emission value a is to be given in m/s 2 and presented by using two and a half significant digits for numbers starting with 1 (e.g. 1,20 m/s 2 , 14,5 m/s 2 ), otherwise two sign

45、ificant digits are sufficient (e.g. 0,93 m/s 2 , 8,9 m/s 2 ). The value of the uncertainty K shall be presented with the same number of decimals as a. Examples of declared vibration emission values are given in annex C.Page 5 EN 12096 : 1997 BSI 1997 6 Verification of declared vibration emission val

46、ues 6.1 General Verification of declared vibration emission values can be required for two different reasons: in order to verify the declared value of one particular machine; or in order to verify the declared value of a batch or production series of machinery. Verification shall be effected by mean

47、s 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 given in 6.2 and 6.3 shall be used for verification under

48、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 laboratories testing the same object. When the declaration c

49、ontains 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 emission value is less than or equal to the value of a+Kas 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 27574-4 for noise. 6.3 Verification of a
