3 Modification to Clause 4
Add the new following sub-clause:
“4.19 Noise
4.19.1 Noise reduction as a safety requirement
4.19.1.1 Noise reduction by design at source and by protective measures
The machine shall generate a noise level as low as practicable. The methodology for designing low-noise
machinery described in EN ISO 11688-1:1998 shall be used.
NOTE EN ISO 11688-2:2000 gives useful information on noise generation mechanisms in machinery.
The main sources causing noise in self-propelled forestry machinery include e.g.:
power source
travelling function
loader
harvesting equipment cutting saw

---------------------- Page: 4 ----------------------
EN 14861:2004/prA1:2007 (E)
The noise reduction measures by design include e.g.:
selecting low noise components e.g. engine;
selecting proper materials;
selecting proper thickness and coating of surfaces;
selecting the cutting saw configuration;
proper maintain of the cutting saw;
selecting low noise exhaust system;
encapsulation of noisiest components of the machine.
4.19.1.2 Noise reduction by information
If after taking all possible technical measures for reducing noise at the design stage a manufacturer considers
that further protection of the operator is necessary, the adequate information shall be listed in the instruction
handbook, see Clause 5.1.
4.19.1.3 Verification of requirements for noise
For the determination of the sound power level and of the emission sound pressure level at the operator’s
position the measurement method given in Annex B shall be used."
4 Modification to 5.1
At the end of 5.1, add the following text:
"v) recommend the use of low-noise operating modes, and/or limited time operation;
x) give a warning of the noise level and recommend the use of hearing ear protection;
z) the instruction handbook and the technical documentation describing the machine prepared by the
manufacturer for the information of the potential users shall:
give the declared noise emission values of the machinery as follows:
the A-weighted sound pressure level at workstations, where this exceeds 70 dB. Should this sound
pressure level not exceed 70 dB, this fact shall be indicated;
the A-weighted sound power level emitted by the machine, where the A-weighted emission sound
pressure level at any workstation exceeds 80 dB.

Annex B
(normative)
Noise test code – (engineering method grade 2)
B.1 Scope
This noise test code specifies all the information necessary for carrying out efficiently and under standardised
conditions the noise emission values of self-propelled forestry machinery.
Noise emission characteristics include emission sound pressure levels at the operator’s station and the sound
power level. The determination of these 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 noise emission values within
specified limits determined by the grade of accuracy of the basic noise standard for the determination of noise
emission values used. Methods for the determination of these noise emission values according to this
normative annex are engineering methods (Grade 2).
For low-noise design, noise emission values in frequency bands are useful and the basic European Standards
EN ISO 3744 and EN ISO 11201 may be used for determining noise emission quantities in frequency bands.
B.2 Emission sound pressure level determination at the operator’s station
B.2.1 Emission sound pressure levels shall be measured in accordance with EN ISO 11201.
B.2.2.1 The following emission sound pressure levels shall be determined at th
