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 p
8、resent standard, in cases where a machine is operated with both 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 deviati

33、ent 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 have been designed a
34、nd 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 of the vibration emission of hand-held and hand-guided machinery. ISO
35、 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 for transducer positioning first introduced in the IEC 60745 series of
36、 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 least disturbance to the operator gripping the machine. It has been f
37、ound that vibrations 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 sup
38、port of the 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.
39、 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 considerably from time to time and depend on many factors, including the operator, the t
40、ask 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 at low magnitudes. It is therefore not recommended that emission values below 2,
41、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 work place are required, then measurements according to ISO 5349 (all parts) in th
42、at 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 occur in real work situations, caused by the use of excessively worn inserted tools.
43、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 portable power tools Measurement of vibrations at the handle Part 11: Fastener driving to
44、ols, could be replaced by a future part of ISO 28927. 4 EN ISO 28927-11:2011 (E) DIN EN ISO 28927-11:2011-05 1 Scope This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held stone hammers. It is a type-test procedure for estab
45、lishing the magnitude of vibration in the gripping areas of a stone hammer when operated in laboratory conditions. It is intended that the results be used to compare different models of the same type of machine. This part of ISO 28927 is applicable to engraving pens and stone hammers intended for us
46、e by stone masons (see Clause 5), driven pneumatically or by other means. It is not applicable to demolition hammers or to chipping hammers primarily intended for use on metal or in construction. NOTE To avoid confusion with the terms “power tool” and “inserted tool”, “machine” is used hereinafter f
