30、as been approved by CEN as a EN ISO 28927-6:2009 without any modification. “Compressors and pneumatic tools, machines and equipment” in collaboration with Technical Committee Introduction This document is a type-C standard as stated in ISO 12100. When requirements of this type-C standard are differe
31、nt 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 portable
32、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 performan
33、ce 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 primar
34、ily 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 rammers vary considerably in typical use. For rammers, the percussion action is the source of
35、 vibration, and the variation is largely due to variations in the handling of the rammer and the damping characteristics of the material worked on. In order to provide a method that gives good measurement reproducibility, this part of ISO 28927 uses a working process where the rammer is used on an e
36、nergy absorber, thereby giving damping characteristics that will be constant over time. 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 average of the upper quartile of typical
37、 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 itself might also be of importanc
38、e. 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
39、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 can be either higher or lower tha
40、n the values obtained using this part of ISO 28927. Higher vibration magnitudes can easily occur in real work situations, caused by an improper combination of butt and rammed material. The vibration test codes given in ISO 28927 supersede those given in ISO 8662, whose parts have been replaced by th
41、e 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 tools, and ISO 8662-13, Hand-held portable power tools Measurement of vibrations at the handle Part 13: Die grinders, could be replace
42、d by future parts of ISO 28927. DIN EN ISO 28927-6:2010-05 EN ISO 28927-6:2009 (E) 4 1 Scope This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held, power-driven rammers. It is a type-test procedure for establishing the magn
43、itude of vibration in the gripping areas of a machine run under specified test 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 rammers, back-fill rammers, pawing rammers, sand rammers and stampers (s
44、ee Clause 5), driven pneumatically or by other means, intended for use in foundries, on building sites, etc., and with, for example, butts or peens made of cast iron or rubber, used for ramming of casting sand or in stamping work. NOTE To avoid confusion with the terms “power tool” and “inserted too
45、l”, machine is used for the former throughout this document. 2 Normative references The following referenced documents are indispensable for the application of this document.
