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
2
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.

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.
6 Vibration measurement direction and location
6.1 Measurement direction
Measurement shall be made in the vertical (Z) direction.
6.2 Measurement location
In the case where the exposed persons are sitting, the transducer mounted in a semi rigid disc shall
be placed on the surface of the seat such that the transducer is located midway between the ischial
tuberosities of the seated person. For comfort reasons, it is acceptable if the centre of the disc is
located slightly in front (up to 5 cm) of the ischial tuberosities (Figure 1).
9
---------------------- Page: 10 ----------------------
EN 13059:2002 (E)
When measurement at the seat base are made (see 7.2), the transducer shall be firmly mounted,
preferably at the centre of the seat base mounting; where this is not possible, it shall be mounted
outside the seat base mounting at the same level as the seat base on a stiff part towards the side of
the truck (see Figure 1) perpendicular to the direction of travel and as close as possible to the seat
centre.
In the case where the exposed persons are standing on a driving or a working platform, the
transducer shall be located (see 5.1.2) at a point immediately adjacent to the feet of the standing
operator (preferably between the feet).
NOTE When the position of the standing driver can influence the results, the intended position of the driver
should be clearly identified.
7 Set up and equipment
7.1 General
The trucks shall be categorized on the basis of tyre types and the wheel mean diameter. The test
track is constructed basically of two obstacles. Further details shall be taken from Table 1 and
Figures 2 and 3.
7.2 Test track
The test track is a straight track and consists of a level, smooth length () surface with two rigid
obstacles each 15 cm wide of rectangular cross section (e.g. hard wood, metal, etc.) to drive over.
The deflection of the obstacle material shall be negligible. Figures 2 and 3 illustrate the test track and
()
obstacles. The length of the test track and the height of the two obstacles shall be chosen from
Table 1. The total length of test track will also include a sufficient distance at each end to allow the
truck to build up to the required speed at the actual start of the run and to slow down and turn at the
end of the run. The test track surface shall be made of hard material like tarmac, concrete, etc. The
smoothness of the surface shall also be such that the r.m.s. acceleration of the frequency weighted
vertical vibration (a ) measured at the seat base or foot plate when the truck is travelling over the
w,z
test track without the obstacles is less than 50 % of the value measured at the same location when
the truck is travelling over the test track with the obstacles. The conditions for the measurements
made without obstacles are the same as with the obstacles. Before starting the measurements it is
essential the test surface shall be cleared of any loose chippings, etc. It is essential that the obstacles
do not move on the test track surface.
NOTE 1 The relationship between measurements made on the seat with and without obstacles is generally
smaller than the same measurements made at the seat base.
NOTE 2 If the truck is equipped with a low frequency suspended cab (resonant frequency below 10 Hz), it is
recommended to make the measurements on the chassis at a point aligned as closely as possible to a point
vertically below the seat centre (see 6.2).
2
NOTE 3 If the vibration measured at the seat base or foot plate with obstacles is less than 0,5 m/s , then the
50 % criterion can be ignored.
7.3 Equipment and condition of the truck
7.3.1 Truck
Measurements shall be carried out on a new, properly serviced truck. Where a single truck is to be
measured and then taken as representative of a truck family, it shall be fitted with equipment
corresponding to that offered by the manufacturer on the standard truck data sheet (lifting devices,
10
---------------------- Page: 11 ----------------------
EN 13059:2002 (E)
batteries, etc.). For individual measurements and special equipment, the specific equipment shall be
listed.
7.3.2 Load
0
Trucks of categories 1, 2, 3 and 4 (see Table 1) shall be tested with a load of % of the rated
60
10
load capacity of the truck at the rated load centre distance. Trucks of category 5 shall be tested
unladen for practical reasons.
Pallet trucks shall be tested with the load support arms raised.
7.3.3 Tyres
The truck shall be fitted with new tyres. Pneumatic tyres shall be properly inflated in accordance with
the truck manufacturer's instructions. The final inflation pressure verification shall be carried out
immediately before and after the vibration testing. If a deviation of more than 10 % is noted on the tyre
inflation pressure before and after the test the vibration tests shall be repeated.
If a truck can be equipped with different types of tyres (e.g. pneumatic tyres, resilient solid tyres,
cushion tyres (bandages) or high-load "non-rubber" solid tyres), at least one series of measurements
shall be made for each type of tyre.
NOTE When the relevant dynamic characteristics of the tyres and truck are known, then the truck can be
tested with just one tyre type and the vibration calculated for other types of tyre.
7.3.4 Trucks with a cab
If or when a truck can be fitted with a cab with or without a suspension, measurements shall be
carried out for both cases.
If the driver's cabin position can be moved horizontally, then measurements shall be carried out at the
extremes of that movement and the highest values of vibration emission shall be reported (see
clause 9). If the driver's position can be moved vertically, then measurements shall be carried out in
the lowest position.
7.3.5 Trucks with seated operators
The seat (or seats) shall be adjusted such that the driver can comfortably reach the necessary
controls. If the truck is equipped with a suspension seat, the suspension shall be adjusted to the
driver's weight and to avoid topping and bottoming of the mobile part of the seat suspension. If a truck
can be fitted with different models of seat, measurements shall be carried out for each model of seat.
7.4 Operators
7.4.1 Standing operator
0
Measurements shall be made with one operator with a mass of 75 kg.
