7、 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 both hands “feed force” is to be taken to mean the sum of
8、 the force of both hands.

34、1:2009 has been approved by CEN as a EN ISO 28927-1:2009 without any modification. “Compressors and pneumatic tools, machines and equipment” in collaboration with Technical Committee DIN EN ISO 28927-1:2010-05 EN ISO 28927-1:2009 (E) 3 Introduction This document is a type-C standard as stated in ISO
35、 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 and built according to the requirements of
36、 this type-C standard. The vibration test codes for portable 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
37、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 EN 60745 series of European standards is followed, representing a deviation from ISO
38、 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 found that vibrations generated by grinders vary considerably in ty
39、pical use. This is largely due to the variances in the unbalance of the machine with the grinding wheel mounted. The unbalance also changes when the wheel is worn through operation. In order to provide a method that gives good measurement reproducibility, the procedure adopted in this part of ISO 28
40、927 uses a test wheel of known unbalance mounted on a machine and run under no-load conditions. The unbalance for the different types of test wheel are chosen to give vibration values that are as far as possible in accordance with ISO 20643. The procedures of ISO 5349 are required whenever exposure
41、at the workplace is to be assessed. Underestimation of the vibration for machines equipped with technical means to automatically reduce unbalances is taken into account by multiplying the vibration values of such machines with a correction factor of 1.3. The values obtained are type-test values inte
42、nded 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 will vary considerably from time to time and depend on many factors, including the operator, the task and the inserted tool or consumable.
43、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 2,5 m/s2be used for estimating the vibratio
44、n 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) in that work situation could be necessary. Vibration val
45、ues 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 unbalanced grinding wheels, worn flanges or bent spindles. The vibration
46、 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). 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-hel
47、d portable power tools Measurement of vibrations at the handle Part 13: Die grinders, could be replaced by future parts of ISO 28927. DIN EN ISO 28927-1:2010-05 EN ISO 28927-1:2009 (E) 4 1 Scope This part of ISO 28927 specifies a laboratory method for measuring hand-transmitted vibration emission at
48、 the handles of hand-held power-driven angle and vertical grinders. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine fitted with a specified test wheel and run under no-load conditions. The method has been established for surface grinding tas
49、ks only. Cutting and sanding generally create lower vibrations. 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 hand-held machines (see Clause 5), driven pneumatically or by other means, intended for grinding, cutting-off and rough sanding, with bonded, coated and super-abrasive products for use on all kinds of materials. It is not applicable to grinders used with wire brushes, nor is it applicable to die or st
