According to EN ISO 12100-2 the risks created

36、 by vibrating machinery need to be minimized and the residual risk from vibration need to be noted in the relevant instruction handbook. This, ideally, will be based on the vibration emission magnitude reported in accordance with this document or the relevant vibration test code, but additional info

37、rmation for use may be required (see Clause 6 in EN ISO 12100-2:2003). It is possible that the type test method may not identify all the mechanisms that generate vibration when the machine is used in the real operational environment. Factors such as the workpiece, the process and the operator can ha

38、ve an important influence on the vibration magnitudes. For this reason the type test measurements cannot replace field measurements to evaluate vibration exposure at the workplace, but should be sufficiently representative to be able to be used for preliminary assessment of risk. Vibration magnitude

39、s in type tests shall be within the range of measurements made in the field, but with less variability. Type tests require accurate and reproducible conditions. It is essential that different laboratories obtain the same results within specified limits. This requires that the process or way in which

40、 the machine is measured is precisely defined. The operating conditions should be well defined, they should preferably be a real process, typical of that for which the machine is designed. If it is intended to be used for a variety of tasks and the vibration is affected significantly by the task, th

41、en more than one task might be used in determination of vibration emission. In some cases an artificial process may be used which is not in line with the typical use of the machine in the field but which provides equivalent data. If two machines produce significantly different magnitudes of vibratio

42、n under real conditions, then the test should be capable of demonstrating this difference. This document is intended to assist technical standardization committees responsible for specific types of machinery in preparing vibration test codes to ensure that such vibration test codes: enable users to

43、make comparisons and to check the declared vibration emission values; are as homogeneous as possible with each individual test code having the same basic structure; are in full accordance with basic type-B standards on measurement of vibration emissions; reflect the latest technical knowledge of met

44、hods of determining the vibration emissions from the specific family of machinery under consideration. A vibration test code for a family of machinery prepared in accordance with this document: a) produces vibration emission data which allow the determination of the vibration state-of-the-art for a

45、family of machinery and the identification of a machine which has significantly greater or smaller vibration emission; b) produces vibration emission values and uncertainties suitable for comparing the emissions of machinery of the same type irrespective of the date or location of the testing; c) pr

46、oduces vibration emission values and uncertainties corresponding to the upper quartile of vibration magnitudes resulting from intended uses of the machinery; d) specifies the operating conditions of the machine during testing that are, so far as practicable, representative of normal use; e) identifi

47、es parameters that have a significant influence on the vibration emission of the machinery; f) specifies installation and mounting conditions of transducers, measurement positions and measurement directions; 5 EN ISO 20643:2008 + A1:2012 (E) DIN EN ISO 20643:2012-10 g) prescribes equipment used duri

48、ng testing and h) requires recording of the values of machinery operating parameters that may influence vibration emission. This document can be used, in the absence of an agreed vibration test code, as a guide to determine vibration emission values and to define test parameters that may influence vibration emission to be recorded. This document is a type-B standard as stated in EN ISO 12100-1. The provisions of this document may be supplemented or modified by a type-C standard. However, for mac
