NOTE If there is an insufficient state of charge concerning the battery of the transmitter, this state should be indicated
(e.g. acoustically or optically) before the function of the equipment is affected in any way (e.g. alteration of the
transmission of control commands).
A.4.2 When a return of power occurs after a power cut affecting the transmitter or receiver, the roller shall
not automatically start to move.
A.4.3 Transmitters and receivers shall be assigned to each other, e.g. on the basis of a code.
NOTE Measures should be taken to ensure that interference with the process of wireless transmission due to
external signals or a combination of several remote control systems with the same transmission frequency does not cause
hazardous movements.
A.4.4 No hazardous movements shall be caused on connection of transmitter or receiver to a power source.
A.4.5 Remote controls shall be constructed to be capable of withstanding any operation stresses and
external influences which may reasonably be expected.
Operating stresses are, for example:
actuation frequencies;
electrical load.
External influences are, for example:
continuous vibration, impacts, shocks;
dampness;
external optical, magnetic, electromagnetic, electrostatic fields;
extraneous light, e.g. interrupted alternating illumination caused by pulsating light sources or gas-
discharge lamps;
solar influence;
ambient temperatures;
interference in power supply as well as variations in voltage and frequency;
effects on connecting cables, linking components of the receiver and the control system of the roller,
which are located in separate casings, due to which a short circuit of any two conductors of such cables
or an interruption of a conductor could be caused which could in turn could lead to a cancellation of the
cut-out.
A.4.6 The beam angle of the transmission element shall not exceed 60°.
NOTE It is intended that this measure limits the possibility of a command being unintentionally issued due to
reflecting walls or obstacles.
A.4.7 The number of the transmitted commands shall be higher than the executed commands because of
data safety.
A.4.8 Due to safety requirements the steering telegrams shall consist of several independent telegrams.
A.4.9 The remote control shall be realised by stateful dependent logic.

Annex B
(normative)
Noise test code for hand-guided and remote-controlled vibratory ground
compaction machines
B.1 Scope
This noise test code specifies all the information necessary to carry out efficiently and under standardised
conditions the determination, declaration and verification of the noise emission characteristics of hand-guided
vibratory ground compaction machines.
Noise emission characteristics include emission sound pressure levels at workstations and the sound power
level. The determination of those quantities is necessary for:
manufacturers to declare the noise emitted;
comparing the noise emitted by machines in the family concerned;
purposes of noise control at the source at the design stage.
The use of this noise test code ensures reproducibility of the determination of the noise emission
characteristics within specified limits determined by the grade of accuracy of the basic noise-measurement
method used. Noise-measurement methods allowed by this standard are engineering methods (grade 2).
Operating and mounting conditions for the determination of noise emission (according to this annex) and
hand-arm vibration (according to Annex C) are identical. It is therefore possible and recommended to record
the noise emission and the hand-arm vibration simultaneously during one measurement. The measuring effort
is thereby reduced.
Pedestrian-controlled machines with a working width of more than 1 m shall be measured according to
Annex D.
B.2 Determination of the A-weighted sound power level
B.2.1 General
This annex specifies additional requirements for the determination of the A-weighted sound power level
according to EN ISO 3744.
B.2.2 Measurement surface
B.2.2.1 Shape and size of the measurement surface
The measurement surface for determining the A-weighted sound power level shall be a hemisphere of radius
r = 4 m that is bounded by the sound-reflecting surface (see Figures B.1 and B.2). The drawbar shall be freely
movable between the upper and lower stops.
B.2.2.2 Microphone positions
Six microphone positions are specified on the hemisphere (see Figures B.1, B.2 and Table B.1).

B.2.3 Test procedure
The machine shall be moved along the centre line of the test course as in usual operation.
For the measurements, the machine shall be in accordance with the manufacturer’s specifications (e.g. if the
extension plates of a vibratory plate are attached on delivery, then they shall remain screwed on during the
measurement).
The drawbar of hand-guided machines shall be freely movable between the upper and lower stops.
Simultaneous measurement at all microphone positions is preferred (it is also possible to perform consecutive
measurements).
For each machine, three measuring cycles shall be carried out.
The compacted material of the test surface shall be loosened before starting of the whole test procedure.
The compacted material of the test surface shall not be loosened between the three measuring cycles.
For the measurement duration t the surface of the test track AB = 5,60 m is compacted by the machine in
M,
forward operation. Subsequently the machine is moved back to the starting point.
Before starting the measurement, the operating temperature shall be reached.
The measurement shall start when the middle of the machine is in line with point A and stops at point B of the
measuring stretch (see Figure B.1). In all cases the compaction shall go on along the whole stretch of gravel.
Therefore it shall be ensured that the machine works with the full compaction power within the measuring
distance.
The r.m.s. values of the sound pressure levels shall be taken for each measurement over the measurement
duration (see Figure B.1).
B.2.4 Repetition of the test and calculation of the sound power level
The A-weighted sound power level shall be determined at least three times. If at least two of the determined
values do not differ by more than 1 dB, further measurements will not be necessary. Otherwise the
measurements shall be continued until two values differing by no more than 1 dB are obtained. The
A-weighted sound power level to be used for calculating the sound power level to be declared is the arithmetic
mean of both highest values that do not differ by more than 1 dB.

---------------------- Page: 15 ----------------------
SIST EN 500-4:2007/kprA1:2008
EN 500-4:2006/prA2:2008 (E)
The A-weighted sound power level of the machine under test and A-weighted emission sound pressure level
at the operator's position shall be rounded down or up to the nearest integral value in dB (< 0,5 round down,
≥ 0,5 round up).
B.2.5 Sound pressure spectrum at a single microphone position on the measurement
surface
If required, sound pressure spectra can be registered at microphone number 10 in accordance with 8.7 of
EN ISO 3744:1995.
B.2.6 Sound pressure level as a function of time
If required, the sound pressure level can be recorded as a function of time at microphone position 10 in
accordance with EN ISO 3744:1995.
B.3 Determination of the A-weighted emission sound pressure level at the operator’s
position
B.3.1 General
This annex specifies additional requirements for the determination of the A-weighted emission sound pressure
level of pedestrian-controlled and remote-controlled vibratory ground compaction machines according to
EN ISO 11201.
B.3.2 Operator’s position
For hand-guided machines, the position of the operator shall be as specified in Figure B.1.
For remote-controlled machines, the position of the operator shall be as specified in Figure B.2.
B.3.3 Test procedure
Since the sound pressure level varies greatly in relation to the operator’s tallness, the operator's height shall
be 1,8 m ± 5 cm.
NOTE Tests conducted for the purpose of this annex proved that a difference in operator's heights of 0,20 m leads to
a difference in the A-weighted emission sound pressure level at the operator’s ear of approximately 1,3 dB.
The test shall be carried out according to B.2.3.
During the whole test, the machine shall be operated by the same person. The person shall be skilled in
handling and operating the machine.
The machine shall be guided with both hands during measurement. Gripping-, feed-, and guiding-forces
appropriate to usual operation shall be applied.
The test track for remote-controlled machines shall be identical to that of hand-guided machines (see
Figure B.1).

B.3.4 Repetition of the test and calculation of the emission sound pressure level
The sound pressure level shall be measured at least three times at each microphone position. If at least two of
the measured values do not differ by more than 1 dB, further measurements will not be necessary. Otherwise
the measurements shall be continued until two values differing by no more than 1 dB are obtained. The A-
weighted emission sound pressure level to be used is the arithmetic mean of the two highest values that do
not differ by more than 1 dB.
The A-weighted sound power level of the machine under test and A-weighted emission sound pressure level
at the operator's position shall be rounded down or up to the nearest integral value in dB (< 0,5 round down,
≥ 0,5 round up).
B.3.5 Sound pressure spectrum at the operator's position
For the emission sound pressure level at the work station in accordance with EN ISO 11201 (microphone
position 14, right ear, see Figures B.1 and B.2).
B.3.6 Sound pressure level as a function of time at the operator's position
If required, the sound pressure level can be recorded as a function of time at microphone position 14 (right
ear).
B.4 Installation and mounting conditions
B.4.1 General
The machines shall be tested during actual operation on a course of gravel according to B.4.2. Testing may
be carried out outdoors or in an appropriate room.
B.4.2 Design of the test surface
The compression ground shall have the following characteristics:
dry gravel with sufficient hardness of a mean gravel diameter of 16 mm (particle size 10 mm to 22 mm),
see grading curve in Figure B.3;
the gravel shall be replaced if the mean gravel diameter has decreased by 30 % or more;
the dumping height of the gravel shall be at least 0,50 m due to the depth effect of the compacting
machines;
the test course of gravel shall have the same horizontal level as the sound-reflecting surface being
rammed in order to prevent the gravel from creeping.
