28、iv ISO 2009 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body intere

29、sted in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical

30、Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the tec

31、hnical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO

32、 shall not be held responsible for identifying any or all such patent rights. ISO 28927-1 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools, machines and equipment, Subcommittee SC 3, Pneumatic tools and machines. This first edition of ISO 28927-1, together with ISO 289

33、27-4, cancels and replaces ISO 8662-4:1994, of which it constitutes a technical revision. The most important changes are vibration measurement in three axes and at both hand positions, new transducer positions, improved definition of transducer positions and orientation, straight grinders dealt with

34、 specifically by ISO 29827-4, rotational speed raised to no-load free running speed, and test wheels modified and their specification improved. ISO 29827 consists of the following parts, under the general title Hand-held portable power tools Test methods for evaluation of vibration emission: Part 1:

BS EN ISO 28927-1:2009ISO 28927-1:2009(E) vi ISO 2009 All rights reservedIntroduction This document is a type-C standard as stated in ISO 12100. When requirements of this type

44、-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 other standards for machines that have been designed and built according to the requirements of this type-C standard. The vibration t

45、est 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 of hand-held and hand-guided machinery. ISO 28927 specifies the operation of the machines under type-test conditions and other require

46、ments for the performance of type tests. The structure/numbering of its clauses follows that of ISO 20643. 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

47、 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 gripping the machine. It has been found that vibrations generated by grinders vary considerably in typical use. This is largely due to the

48、variances in the unbalance of the machine with the grinding wheel mounted. The unbalance also changes when the wheel is worn through operation. In order to provide a method that gives good measurement reproducibility, the procedure adopted in this part of ISO 28927 uses a test wheel of known unbalan

49、ce mounted on a machine and run under no-load conditions. The unbalance for the different types of test wheel are chosen to give vibration values that are as far as possible in accordance with ISO 20643. The procedures of ISO 5349 are required whenever exposure at the workplace is to be assessed. Underestimation of the vibration for machines equipped with technical means to automatically reduce unbalances is taken into account by multiplying the vibration values of such machines
