In DIN 45679, “feed force” is force applied by only one hand; in ISO 15230 feed force refers to both hands (there it is defined as the “sum of the push force of both hands”). In the present standard, in cases where a machine is operated with bo

8、th hands “feed force” is to be taken to mean the sum of the force of both hands. In the Introduction, it is stated that the basic principle for transducer positioning in accordance with EN 60745 has been adopted, which represents a deviation from ISO 20643:2005.

33、28927-10:2011 (E) DIN EN ISO 28927-10:2011-07 3Introduction 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 requ

34、irements 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 (all parts) are based on ISO 20643, which gives general specifications for the measurement

35、 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. The structure/numbering of its clauses follows that of ISO 20643. The basic principle

36、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 next to the hand in the area between the thumb and the index finger, where they give the

37、 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 dominating source of vibration and the variation in the result is affected by the quality

38、 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 magnitudes in real-world use of the machines. However, the actual magnitudes vary conside

39、rably 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 working conditions the influences of the operator and process can be particularly important

40、 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 accurate values for a specific w

41、ork 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 values obtained using this part of ISO 28927. Higher vibration magnitudes can easily occu

42、r 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 replaced by the corresponding parts of ISO 28927 (see Foreword). NOTE ISO 8662-11, Hand-held

43、 portable power tools Measurement of vibrations at the handle Part 11: Fastener driving tools, could be replaced by a future part of ISO 28927. EN ISO 28927-10:2011 (E) DIN EN ISO 28927-10:2011-07 41 Scope This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration

44、emission at the handles of hand-held power driven percussive machines with and without rotary action portable rock drills, plug hole drills, rotary hammers, breakers (e.g. pavement breakers, concrete breakers or road breakers), riveting hammers, chipping hammers, pick hammers or similar. It is a typ

45、e-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 hard materials, such as ro

46、ck 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 with direct mechanical impac

47、t 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 the same type of machine.

48、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.
