6、 Technical Committee CEN/TC 231 “Mechanical vibration and shock” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Akustik, Lrmminderung und Schwingungstechnik im DIN und VDI (Acoustics, Noise Control and Vibration Engineering Standards Comm

7、ittee in DIN and VDI), Working Committee NA 001-03-07-02 (NALS/VDI C 7.2) Hand-Arm-Schwingungen. This standard covers polishers and rotary, orbital and random orbital sanders. For other types of sanders see DIN EN ISO 8662-13, DIN EN ISO 28927-1 and DIN EN ISO 28927-4. In DIN 45679, “feed force” is

8、force applied by only one hand; in ISO 15230 feed force refers to both hands (there it is defined as the “sum of the push force of both hands”). In the present standard, in cases where a machine is operated with both hands “feed force” is to be taken to mean the sum of the force of both hands. The D

33、ation with Technical Committee Introduction This document is a type-C standard as stated in ISO 12100. When requirements of this type-C standard are different from those which are stated in type-A or -B standards, the requirements of this type-C standard take precedence over the requirements of the

34、other standards for machines that have been designed and built according to the requirements of this type-C standard. The vibration test codes for portable hand-held machines given in ISO 28927 are based on ISO 20643, which gives general specifications for the measurement of the vibration emission o

35、f hand-held and hand-guided machinery. ISO 28927 specifies the operation of the machines under type-test conditions and other requirements for the performance of type tests. The structure/numbering of its clauses follows that of ISO 20643. The basic principle for transducer positioning first introdu

36、ced in the EN 60745 series of European standards is followed, representing a deviation from ISO 20643 for reasons of consistency. The transducers are primarily positioned next to the hand in the area between the thumb and the index finger, where they give the least disturbance to the operator grippi

37、ng the machine. It has been found that vibrations generated by polishers and all types of sanders vary considerably in typical use. The variation is largely due to variations in the unbalance of the sanding or polishing pad and to differences in the contact between the inserted tool and the surface

38、of the work piece. Orbital and random orbital sanders are sensitive to changes in the weight of the sanding pad because the weight is counterbalanced by counterbalance weights in the machine. The vibration value also depends to a large extent on the skill of the operator. This part of ISO 28927 uses

39、 a real working process for the test. In order to provide a method that gives good measurement reproducibility, the procedure chosen to give vibration values as far as possible in accordance with ISO 20643 is described in detail and it is essential that it be followed exactly. The procedures of ISO

40、5349 are required whenever exposure at the workplace is to be assessed. The values obtained are type-test values intended to be representative of the average of the upper quartile of typical vibration magnitudes in real-world use of the machines. However, the actual magnitudes will vary considerably

41、 from time to time and depend on many factors, including the operator, the task and the inserted tool or consumable. The state of maintenance of the machine itself might also be of importance. Under real working conditions the influences of the operator and process can be particularly important at l

42、ow magnitudes. It is therefore not recommended that emission values below 2,5 m/s2be used for estimating as estimates of the vibration magnitude under real working conditions. In such cases, 2,5 m/s2is the recommended vibration magnitude for estimating the machine vibration. If accurate values for a

43、 specific work place are required, then measurements (according to ISO 5349) in that work situation could be necessary. Vibration values measured in real working conditions can be either higher or lower than the values obtained using this part of ISO 28927. Higher vibration magnitudes can easily occ

44、ur in real work situations, caused by the use of excessively unbalanced inserted tools, sanding pads with the wrong weight, worn backing pads or bent spindles. The vibration test codes given in ISO 28927 supersede those given in ISO 8662, whose parts have been replaced by the corresponding parts of

45、ISO 28927 (see Foreword). NOTE ISO 8662-11, Hand-held portable power tools Measurement of vibrations at the handle Part 11: Fastener driving tools, and ISO 8662-13, Hand-held portable power tools Measurement of vibrations at the handle Part 13: Die grinders, could be replaced by future parts of ISO

46、28927. DIN EN ISO 28927-3:2010-05 EN ISO 28927-3:2009 (E) 4 1 Scope This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held, power-driven, portable polishers and rotary, orbital and random orbital sanders used for surface-fin

47、ishing processes, not for material removal. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine when operating under type-test conditions. It is intended that the results be used to compare different models of the same type of machine. This part

48、 of ISO 28927 is applicable to hand-held machines (see Clause 5), driven pneumatically or by other means. It is not applicable to straight grinders equipped with a sanding wheel or to belt sanders. NOTE To avoid confusion with the terms “power tool” and “inserted tool”, machine is used for the forme
