29、e 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 interested in a subject for which a technical committee has been established has the right to be represented on that
30、 committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in ac
31、cordance 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 technical committees are circulated to the member bodies for voting. Publication as an International Standard req
32、uires 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.

This first edition of ISO 29827-9, together with ISO 29827-11, cancels and replaces ISO 8662-14:1996, of which it constitutes a technical revision. The most important
34、 changes are vibration measurement in three axes and at both hand positions, new transducer positions, stone working tools become stone hammers and the subject of a separate Part 11, and reference to energy absorbers deleted and all tools now tested on a mild steel plate or concrete block.

44、hts 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 standards for
45、 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-held and han
46、d-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 the EN 60745
47、 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 machine. It
48、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 in the handling of the machine and the characteristics of the material being worked
49、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 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 inte
