31、). 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 committee. International organizations, governmental and no
32、n-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 accordance with the rules given in the ISO/IEC Directives, Par
33、t 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 requires approval by at least 75 % of the member bodies casting
34、 a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 28927-2 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools,
35、 machines and equipment, Subcommittee SC 3, Pneumatic tools and machines. This first edition of ISO 28927-2 cancels and replaces ISO 8662-7:1997, of which it constitutes a technical revision. The most important changes are vibration measurement in three axes and at both hand positions, new transduce
36、r positions, improved definition of transducer positions and orientation, and all types of screwdrivers and nutrunners, excepting one-shot nutrunners, now covered.

46、roduction 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 machines that
47、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 hand-guided machin
48、ery. 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 series of Euro
49、pean 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 has been found that vibrations generated by wrenches and nutrunners during tightening and unfastening of threaded fasteners vary considerably in typical use. For impact and impulse machines, this is l
