5、oreword This standard has been prepared by Technical Committee ISO/TC 118 “Compressors and pneumatic tools, machines and equipment”, Subcommittee SC 3 “Pneumatic tools and machines” in collaboration with Technical Committee CEN/TC 231 “Mechanical vibration and shock” (Secretariat: DIN, Germany). The

6、 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 Committee in DIN and VDI), Working Committee NA 001-03-07-02 (NALS/VDI C 7.2) Hand-Arm-Schwingungen.

7、In DIN 45679, “feed force” is 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

8、the force of both hands. The DIN Standards corresponding to the International Standards referred to in the EN are as follows: ISO 5349 series DIN EN ISO 5349 series ISO 8662-11 DIN ISO/TS 8662-11 ISO 8662-13 DIN ISO/TS 8662-13 ISO 12100 DIN EN ISO 12100 ISO 20643 DIN EN ISO 20643 IEC 60745 series DI

9、N EN 60745 series The national standards are given in Annex NA “Bibliography”. Amendments This standard differs from DIN EN ISO 8662-14:1997-03 as follows: a) The standard only covers scaling hammers and needle scalers. b) Vibrations are measured in three axes and at both hand positions. c) New tran

10、sducer locations have been specified for the measurements. d) The directions of measurement have been modified. e) Energy absorbers have been deleted and all tools are now tested on a mild steel plate or concrete block.

Endorsement notice The text of ISO 28927-9:2009 has been approved by CEN as a EN ISO 28927-9:2009 without any modification. “Compressors and pneumatic tools, machines and equipment

32、” in collaboration with Technical Committee DIN EN ISO 28927-9:2010-05 EN ISO 28927-9:2009 (E) 3 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

33、this type-C standard take precedence over the requirements of the 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 gene

34、ral specifications for the measurement of the vibration emission of 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 2

35、0643. The basic principle for transducer positioning first introduced 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 fi

36、nger, where they give the least disturbance to the operator gripping the machine. It has been found that vibrations generated by scaling hammers and needle scalers vary considerably in typical use. The percussive action is the prime source of vibration, and the variation is largely due to variations

37、 in the handling of the machine and the characteristics of the material being worked on. Differences in the support of the material also cause differences in vibration. This part of ISO 28927 uses a working process where the machine is used to work on a steel or concrete surface. In order to achieve

38、 good reproducibility, it is important that the material have good support and that the inserted tools used be in good condition. The procedures of ISO 5349 are required whenever exposure at the workplace is to be assessed. The values obtained are type-test values intended to be representative of th

39、e average of the upper quartile of typical vibration magnitudes in real-world use of the machines. However, the actual magnitudes will vary considerably 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

40、 machine itself might also be of importance. Under real working conditions, the influences of the operator and process can be particularly important at low magnitudes. It is therefore not recommended that emission values below 2,5 m/s2be used for estimating the vibration magnitude under real working

41、 conditions. In such cases, 2,5 m/s2is the recommended vibration magnitude for estimating the machine vibration. If accurate values for a specific work place are required, then measurements (according to ISO 5349) in that work situation could be necessary. Vibration values measured in real working c

42、onditions can be either higher or lower than the values obtained using this part of ISO 28927. The vibration test codes given in ISO 28927 supersede those given in ISO 8662, whose parts have been replaced by the corresponding parts of ISO 28927 (see Foreword).

43、wer 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 28927. DIN EN ISO 28927-9:2010-05 EN ISO 28927-9:2009 (E) 4 1 Sco

44、pe This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held, power-driven scaling hammers and needle scalers. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine run under

45、 specified test conditions. It is intended that the results be used to compare different models of the same type of machine. This part of ISO 28927 is applicable to engraving pens, scabblers, scaling hammers and needle scalers (see Clause 5), driven pneumatically or by other means, intended for pain

46、t, rust or scale removal with reciprocating work tools or needles and for all kinds of materials. NOTE To avoid confusion with the terms “power tool” and “inserted tool”, machine is used for the former throughout this document. 2 Normative references The following referenced documents are indispensa
