Remote controls for machines with attending operator
A.1 General
ISO 15817:2012 applies with the following additions for wireless remote controls.
A.2 Safety requirements and measures
All travel movements shall be switched off automatically by the receiver if the distance between the
transmitter hold by the operator and the machine is less than 2 m.
All travel movements shall be switched off automatically by the control system if the machine is leaving
the work- and travel area (maximum distance between transmitter and machine less than 50 m).
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).
Transmitters and receivers shall be assigned to each other.
ISO 15817:2012, 4.4.2.4 is considered to be fulfilled by a lockable storage place on the machine for the
remote control box.
ISO 15817:2012, 4.5.3 applies with the following modification: An emergency stop on the machine is not
required.
No movements shall be caused on connection of transmitter or receiver to a power source.
The alignment of the remote control shall not exceed horizontally ± 30°.
NOTE It is intended that this measure limits the possibility of a command being unintentionally issued due to
reflecting walls or obstacles.
A.3 Components and equipment
It shall be possible to operate the controls while wearing protective gloves.
If programming is used in the process of transmitting commands in conjunction with the remote controls,
it shall only be possible to alter the programme with a special tool.
The description of type shall clearly indicate the relationship between transmitter and receiver.
The following message shall be legibly and durably shown on the transmitter (either by text or by an
appropriate pictogram):
“Check the operational functionality of the remote control system prior to use.”
ISO/DIS 20500-4:2020(E)
Annex B
(normative)
Noise test code for vibratory plates and vibratory rammers
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
vibratory plates and vibratory rammers.
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 International 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 to record the noise
emission and the hand-arm vibration simultaneously during one measurement. The measuring effort is
thereby reduced.
Noise emission of machines exceeding a working width of 1 m shall be determined according to Annex D.
NOTE 1 Tests conducted with machines exceeding a working width of 1 m according to this Annex lead to
irreproducible results due to reflection by the apron of the test course.
NOTE 2 The noise evaluation procedures as laid down in this International Standard aim at ensuring the
reproducibility of the measurements of the noise emission of the machine. This determination does not necessarily
reflect the noise emission during operation on construction sites.
NOTE 3 The sound pressure spectra may be registered at microphone position 10 in accordance with
ISO 3744:2010, 8.7.
NOTE 4 The sound pressure level may be recorded as a function of time at microphone position 10.
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 ISO 3744:2010.
ISO/DIS 20500-4:2020(E)
For all measurements carried out under free field over a reflecting plane conditions according to
ISO 3744:2010 the environmental correction factor K shall be set to 0.

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 if any shall be freely movable between the upper and lower stops.
Simultaneous measurement at all microphone positions is preferred (consecutive measurements are also
possible and allowed).
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
M,
in forward operation. Subsequently the machine is moved back to the starting point.
Before starting the measurement, the machine operating temperature as defined by the manufacturer
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.
