The work of prepa
25、ring 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 non-governmental, in l
26、iaison 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, Part 2. The main task o
27、f 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 a vote. Attention i
28、s 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 28927-11 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools, machines and equip
29、ment, Subcommittee SC 3, Pneumatic tools and machines. This first edition of ISO 28927-11 cancels and replaces ISO 8662-14:1996, 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 are u
30、sed, definition of the transducer positions and orientation has been improved, needle scalers have been moved to a new part “Scaling hammers and needle scalers” (ISO 28927-9), and energy absorber has been deleted and all tools are tested on stone.

42、e-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 have been designed and built acc
43、ording to the requirements of this type-C standard. The vibration test codes for portable hand-held machines given in ISO 28927 (all parts) 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 (all
44、parts) 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 IEC 60745 series of European st
45、andards 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 vi
46、brations generated by stone hammers vary considerably in typical use. For stone hammers, impacting action is the prime source of vibration. The variation is largely due to variations in the handling of the machine and the characteristics of the material to work on. Differences in the support of the
47、material also cause differences in vibration. This part of ISO 28927 uses a working process where the machine is used to work on a stone surface. To improve reproducibility of the test, it is important that the material has good support and that inserted tools used are in good condition. The values
48、obtained are type-test values intended to be representative of the average of the upper quartile of typical vibration magnitudes in real-world use of the machines. However, the actual magnitudes vary considerably from time to time and depend on many factors, including the operator, the task and the
49、inserted tool or consumable. The state of maintenance of the 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 conditions. In such cases, 2,5 m/s2is the recommended vibration magnitude for estimating the machine vibration. If accu
