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 ISO 12100".
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.

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 (a ) of whole body vertical frequency — weighted vibration in
wz
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 a shall be measured,
w
calculated and declared according to EN 1032:2003.
Standing driver
a Mean value of n root-mean-square frequency weighted vertical acceleration values of a valid test
wzF
series measured on the floor of the driving position with one standing driver.
Seated driver
a Average of acceleration mean values obtained for each of the two drivers for a valid test series
wzS
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;
