7.3 Sound and Vibration Specifications
The required sound specifications, per Annex VIII, Directive 2000/14/EC of the EC-
Machine Regulations, are:
-the sound pressure level at operator’s location (L
pA
):
91.1 dB(A) (CRT 48-35L)
93.5 dB(A) (CRT 48-35V)
96.3 dB(A) (CRT 48-34V and CRT 48-31V)
-the guaranteed sound power level (L
WA
):
110.2 dB(A) (CRT 48-35L and CRT 48-35V)
112.8 dB(A) (CRT 48-34V and CRT 48-31V)
These sound values were determined according to ISO 3744 for the sound power
level (L
WA
) and ISO 11204 for the sound pressure level (L
pA
) at the operator’s
location.
The weighted effective acceleration value, determined according to ISO 5349-1
and ISO 2631, is:
-for whole body:
0.274 m/s2 (CRT 48-35L)
0.381 m/s2 (CRT 48-35V)
0.208 m/s2 (CRT 48-34V and CRT 48-31V)
-for hand/arm:
1.37 m/s2 (CRT 48-35L)
1.54 m/s2 (CRT 48-35V)
1.31 m/s2 (CRT 48-34V and CRT 48-31V)
The sound and vibration specifications were obtained with the unit operating on
fully cured, water wetted concrete at nominal engine speed.
