The Machinery Directive 98/37/EC amended by Directive 98/79/EC requires that vibration
measurements be made and values put into the instruction books if the whole-body vibration values
are greater than 0,5 m/s .
A type test procedure is specified so that different establishments obtain comparable results of
vibration measurements within specified limits. The specified procedure consists of measuring the
vibration transmitted to the operator when the truck is travelling over a test track made of a straight
length of good quality surface with obstacles whose characteristics depend on the type of truck and its
wheel characteristics.
The annexes A, B, C and D are informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Czech
Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta,
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

Under preparation, using the Vienna agreement with ISO lead.
Introduction
This European Standard has been prepared to be a harmonized standard to provide one means of
conforming to the essential safety requirements of the Machinery Directive and associated EFTA
regulations. This European Standard is a type C standard as stated in EN 1070.
The aim of this standard is to provide a method for the measurement of vibration emission transmitted
to the whole body of operators of industrial trucks which will enable the information requirements of
the Machinery Directive to be satisfied. It is intended that the results obtained also can be used to
compare industrial trucks of the same category or a given truck when equipped with different seats or
tyres, etc. This standard cannot be used for field measurements to determine the daily exposure of
the operator to vibration.
For the measurements trucks shall be fitted with equipment corresponding to that offered by the
manufacturers on the standard truck data sheet (lifting devices, batteries, etc.).
Type test measurements require accurate and reproducible results. It is essential that different
establishments obtain comparable results within specified limits. This requires that the process or way
in which the machinery is used during the measurement is precisely defined. This process will
reproduce the whole-body vibration values typical of the machinery when in normal travelling use.
In the case of industrial trucks, there may be three predominant operating modes: travelling, lifting
and engine idling; of these, only travelling exposes the driver to significant whole-body vibration.
Therefore, in accordance with EN 1032, the test for whole-body vibration is based on the travelling
operating mode.
Research has shown that the magnitude of hand-arm vibration on the steering wheel or control levers
of trucks will normally be lower than 2,5 m/s . Therefore no test method has been developed for its
measurement.
In practice, exposure over a working day is a mixture of the three modes and the average vibration
values will generally be lower than the values given by this standard. Fitting the industrial trucks with
different seats, changing the tyres, etc. can lead to different vibration values. Due to the specific
operation of industrial trucks however, the existing EN 1032 standard cannot be applied directly, so
that preparation of this standard for industrial trucks became necessary.
Although studies showed that it is possible to obtain repeatable and representative results with all-
terrain trucks tested on an artificial test track, this family of trucks is covered by Informative annex A.
The reason is that an inexplicable difference of about 20 % was found in the emission from one truck
when it was tested at two different times of the year. Further consideration should be given to
including all-terrain trucks in the normative section of the standard when more data is available for
these trucks.
For the verification of the measurements the uncertainty is fixed at 0,3 times the vibration emission
value reported in accordance with EN 12096. Further consideration should be given to revise this
range of uncertainty when emission vibration data obtained from different places is available.
1 Scope
This European Standard is a type test procedure for establishing the values of vibration emission
transmitted to the whole body of operators of industrial trucks under specified conditions. It is not
applicable to hand-arm vibration.
This standard is applicable to powered industrial trucks listed in ISO 5053:1987. The annex A is
applicable for "all-terrain" trucks. It also applies to other powered industrial trucks not covered by
ISO 5053:1987, e.g. variable-reach trucks and "low-lift" "order picking" trucks, etc.
NOTE  The standard may however be useful also for existing trucks.
This standard is not applicable to non-stacking "low-lift" straddle carriers (as specified in 3.1.3.2.3 of
ISO 5053:1987) and stacking "high-lift" straddle carriers (as specified in 3.1.3.1.11 of ISO 5053:1987).
The test results, however, are not applicable to the determination of whole-body vibration exposure.

publications. These normative references are cited at the appropriate places in the text, and the

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 1070, ISO 2041,
ISO 5053 and ISO 5805, and the following apply.
3.1
truck family
trucks sharing the same major components that influence vibration emission
3.2
wheel diameter
arithmetic mean of the outside diameters of the load bearing wheels, e.g. : if the truck has some
wheel(s) of diameter D , some wheel(s) of diameter D and some wheel(s) of diameter D , the wheel
1 2 3
mean diameter equals (D + D + D )/(number of tyre sizes fitted)
1 2 3
The outside diameter, D, is the maximum in service diameter quoted in the ETRTO manual (see
annex D) for the size(s) and type(s) of tyres fitted. If a tyre is not listed, consult the tyre's
manufacturer.
3.3
tyre
the tyre can be pneumatic or solid. Amongst the solid tyres a distinction can be made between high-
load "non-rubber" solid tyres (Vulkollan, Contilan, etc.) and rubber solid tyres
Rubber solid tyres can be fitted to a cylindrical or conical base (e.g. cushion "bandages") or to a
pneumatic tyre rim (e.g. super elastic tyres).
3.4
seat base
surface on which the seat and its suspension, if fitted, are mounted
3.5
seat pan
seat surface on which the operator is seated
4 Quantities to be measured
The quantities to be measured are as follows:
4.1 a : root mean square (r.m.s.) acceleration of whole-body vertical frequency-weighted
w,z
vibration in accordance with EN 1032;
4.2 a : mean value of N r.m.s. weighted vertical acceleration values of a valid test series
F
w,z
measured on the floor of the driving position with one standing operator;
4.3 a : average of acceleration mean values obtained for each of the two operators for a valid
w,zS
test series measured on the seat pan under the seated operator;
4.4 the mean truck 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 5.2;
4.5 pneumatic tyre pressures shall be checked;
4.6 ambient air temperature.
5 Instrumentation
5.1 Whole-body vibration
5.1.1 General
The specifications for the instrumentation given in EN 1032:1996, 5.1, for the measurement of whole-
body vibration apply.
5.1.2 Transducers
General requirements for mounting of vibration transducers are given in EN 1032:1996, 5.2. In the
case where the measurements are made on a seat pan the transducer shall be mounted in a semi
rigid disc as described in EN 1032:1996, 5.2.
In the case where the measurements are made at the seat base or on the floor the transducer shall
be firmly fixed to rigid parts of trucks e.g. by means of a magnet, or adhesive, etc.
NOTE In the case of stand on trucks, it is convenient to mount the transducer on a light rigid plate upon
which the operator can place both feet.
5.1.3 Frequency weighting
Frequency weighting and band limiting characteristics shall be in accordance with 5.3 of
EN 1032:1996.
5.1.4 Integration time
For each run, the r.m.s. acceleration shall be a linearly integrated average over one complete test run
(see 8.2).
5.2 Truck speed
The truck speed on the test track shall be measured using instruments measuring the average speed
with an accuracy of
5 %.
NOTE An alternative method is to measure the time to travel over the full length of the test track. From
knowledge of the length of the track and the time taken to travel it, the truck average speed is calculated.
