The work of preparing International Standards is normally carried out through ISO
29、technical committees. Each member body interested 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 clo
30、sely with the International Electrotechnical 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. Dra
31、ft International Standards adopted by the technical 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 docu
32、ment may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

43、09 All rights reservedIntroduction 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 other sta
44、ndards 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 of hand-he
45、ld 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 introduced in th
46、e 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 gripping the ma
47、chine. 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 of the wo
48、rk 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 a real w
49、orking 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 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 vib
