7.4 Sound Measurements
The operating sound level, measured per the requirements of Appendix 1,
Paragraph 1.7.4.f of the EC-Machine Regulations, is:
the guaranteed sound power level (L
WA
) = 106 dB(A).
the sound pressure level at operator’s location (L
pA
) = 88.0 dB (A).
This sound value was determined according to ISO 6394:1998 for the sound power
level (L
WA
).
7.5 Measurements of Operator Exposure to Vibration
The operator of this machine should expect to be exposed to vibration levels listed
below when using the machine in performance of its normally intended function:
Hand/arm vibration levels do not exceed 2.5 m/s
2
. This is the representative
value of the weighted root mean square (rms) acceleration to which the hands
and arms are subjected. The weighted rms value measured according to ISO
5349-1 is 1.28 m/s
2
.
Whole body vibration levels do not exceed 0.5 m/s
2
. This is the representative
value of the root mean square (rms) acceleration to which the whole body is
subjected. The weighted rms value measured according to ISO 2631-1 is 0.27
m/s
2
.
The results are compliant to the limit and action vibration values (hand/arm and
whole body) as specified in European directive 2002/44/EC.
Vibration
Uncertainties
Hand-transmitted vibration was measured per ISO 5349-1. This measurement
includes an uncertainty of 1.5 m/sec
2
per EN500-4:2001.
Whole body vibration was measured per ISO 5349-1. This measurement includes
an uncertainty of 0.3 m/sec
2
per EN500-4:2001.
