BS EN ISO 28927-10:2011EN ISO 28927-10:2011 (E)Introduction 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
26、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 portable hand-held machines given in ISO 28927 (al
27、l 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 parts) specifies the operation of the machines under type-test conditions and other requirements for the performance of type tests.
28、 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 standards is followed, representing a deviation from ISO 20643 for reasons of consistency. The transducers are primarily positioned n
29、ext 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 percussive machines vary considerably in typical use. For percussive machines, the impacting action is the do
30、minating source of vibration and the variation in the result is affected by the quality of the working/inserted tool, the worked material and the skill of the operator. The values obtained are type-test values intended to be representative of the average of the upper quartile of typical vibration ma
31、gnitudes 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 inserted tool or consumable. The state of maintenance of the machine itself might also be of importance. Under real work
32、ing 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 vibrat
33、ion magnitude for estimating the machine vibration. If accurate values for a specific work place are required, then measurements according to ISO 5349 (all parts) in that work situation could be necessary. Vibration values measured in real working conditions can be either higher or lower than the va
34、lues obtained using this part of ISO 28927. Higher vibration magnitudes can easily occur in real work situations, caused by the use of excessively worn or bent inserted tools. The vibration test codes given in ISO 28927 (all parts) supersede those given in ISO 8662 (all parts) , which has been repla
35、ced by the corresponding parts of ISO 28927 (see Foreword).

38、s or similar. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine fitted with an inserted tool bit. This part of ISO 28927 is applicable to hand-held machines (see Clause 5), driven pneumatically or by other means, intended for making holes in h
39、ard materials, such as rock and concrete. It is also applicable to breakers intended to work downwards to break hard materials (concrete, rock, pavement, asphalt, etc.) and for hammers intended to work in any direction to perform riveting or chiselling work. It is not applicable to impact drills wit
40、h direct mechanical impact mechanisms. This part of ISO 28927 is not applicable to jack leg type rock drills and push feed rock drills, which are hand guided (the feed force is not applied by hand, but by an additional device). It is intended that the results be used to compare different models of t
41、he same type of machine. NOTE To avoid confusion with the terms “power tool” and “inserted tool”, “machine” is used hereinafter for the former. 2 Normative references The following referenced documents are indispensable for the application of this document.
