1.5 Sound Measurements
The operating sound levels, measured per the requirements of Appendix 1, Paragraph 1.7.4.f of the EC-Machine
Regulations, are:
- the sound pressure level at operator's location (L
pA
) = 92 dB(A).
- the sound power level (L
WA
) = 103 dB(A).
These sound values were determined according to ISO 3744 for the sound power level (L
WA
) and ISO 6081 for the
sound pressure level (L
pA
) at the operator's location.
1.6 Vibration Measurements
The operating hand/arm vibration level, measured per the requirements of enclosure 1, Paragraph 2.2 or 3.6.3 of the
EC-Machine Regulations, is approximately 16 m/s
2
.
The weighted effective acceleration value was determined according to ISO 8662 Part 1.
The sound and vibration measurements were obtained with the machine operating on crushed gravel at nominal
engine speed.
