EN 1915-3:2004 (E) 4 Introduction The aim of this European Standard is to deal with vibration as a hazard and to provide methods for the measure-ment and reduction of vibration emission transmitted to the whole body of drivers of GSE, when driving. For deter-mining whole body vibrations under stationary operating conditions and hand-arm vibrations EN 1032:2003 is used. It is intended that the results obtained can also be used to compare GSE of the same category or a given GSE when equipped with different seats or tyres, etc. Fitting different seats, changing the tyre specification, etc. can lead to different vibration values. Due to the specific operation of GSE, however, EN 1032:2003 cannot be applied directly for whole body vibration under driving condi-tions, and therefore, the preparation of this European Standard for GSE has become necessary. This European Standard cannot be used for field measurements to determine the daily exposure of the driver to vibration. This European Standard is a Type C standard as stated in EN 1070:1998. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indi-cated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the pro-visions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.

EN 1915-3:2004 (E) 5 1 Scope This European Standard deals with vibration reduction as a safety requirement. It also specifies the methods for determining the vibration emission transmitted to the whole body of drivers standing and/or seated on freely moveable GSE, when driving for purposes of type evaluation, declaration and methods of verifying vibration emission. The test results are not applicable to the determination of whole body vibration exposure of persons. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1032:2003, Mechanical vibration — Testing of mobile machinery in order to determine the vibration emission value. EN 1070:1998, Safety of machinery — Terminology. EN 1915-1:2001, Aircraft ground support equipment — General requirements — Part 1: Basic safety requirements.

EN 1915-3:2004 (E) 6 4 Vibration reduction Vibration emission is a significant hazard, which shall be reduced to the lowest level taking into account the techni-cal progress and the available technical measures for vibration control. The main source causing whole body vibration is the interaction between the machine and the surface of the ground. Measures for reducing the vibrations can be:  pneumatic instead of solid tyres;  suspension;  vibration isolated cabin;  suspension seat;  shock absorbers. After taking at design and manufacturing all possible general technical measures for vibration reduction the instruc-tion handbook shall, when appropriate, identify any additional vibration reduction measures, which can be taken by the user. Furthermore, it shall, where appropriate, recommend organisational measures such as the use of low-vibration operating modes, and/or limited time of operation. 5 Quantities to be measured The quantities to be measured are as follows: a) The root mean square (r.m.s.) acceleration )(wza of whole body vertical frequency — weighted vibration in accordance with EN 1032:2003. Measurements shall be made in the vertical (z) direction. If there are substantial vibration components as defined in EN 1032:2003, Clause 6 in the horizontal directions, the summation aw shall be measured, calculated and declared according to EN 1032:2003.  Standing driver
wzFa Mean value of n root-mean-square frequency weighted vertical acceleration values of a valid test series measured on the floor of the driving position with one standing driver.  Seated driver
wzSa Average of acceleration mean values obtained for each of the two drivers for a valid test series measured on the seat base under the seated driver. NOTE 1 The symbols F and S designate “Floor” and “Seat”; b) The mean GSE speed when travelling on the test track. This may be determined from the time taken to drive along the test track or by means of the measuring instruments specified in 6.5; c) Pneumatic tyre pressures (see also 8.2.2); d) Ambient air temperature.
