When requirements of this type-C standard are dif

39、ferent 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 test codes for porta

40、ble 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 requirements for the perfo

41、rmance 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 transducers are pr

42、imarily 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 drills vary considerably in typical use. For impact drills, the impacting action is the d

43、ominant source of vibration, with variation in the result being affected by the quality of the drill bit, the work piece and the skill of the operator. For drills without impacting action, the variation is largely due to variations in the unbalance of the chuck and inserted tool, and the runout of t

44、he chuck. In some drilling operations, the interaction between the drill bit and the work piece can cause vibration. This part of ISO 28927 uses a real working process for the test. In order to provide a method that gives good measurement reproducibility, the procedure chosen to give vibration value

45、s 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 averag

46、e of the upper quartile of typical vibration magnitudes in real-world use of the machines. However, the actual magnitudes will vary considerably from time to time and depend on many factors, including the operator, the task and the inserted tool or consumable. The state of maintenance of the machine

47、 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 conditio

48、ns. In such cases, 2,5 m/s2is the recommended vibration magnitude for estimating the machine vibration. If accurate values for a specific work place are required, then measurements (according to ISO 5349) in that work situation could be necessary. Vibration values measured in real working conditions

49、 can be either higher or lower than the values obtained using this part of ISO 28927. Higher vibration magnitudes can easily occur in real work situations caused by the use of worn or bent drill bits, worn or unbalanced chucks, or a poor combination of drilling power, drill-bit size and feed force. The vibration test codes given in ISO 28927 supersede those given in ISO 8662, whose parts have been replaced by the corresponding parts of ISO 28927 (see Foreword).
