6.3 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

): 91.2 dB(A) (CRT

36-24A), and 91.7 dB(A) (CRT 36-25).

-the guaranteed sound power level (L

): 104.7 dB(A) (CRT 36-24A)

and 108.6 dB(A) (CRT 36-25)

These sound values were determined according to ISO 3744 for the

sound power level (L

) and ISO 11204 for the sound pressure level

) at the operator’s location.

The weighted effective acceleration value, determined according to

ISO 5349-1and ISO 2631, is:

-for whole body: 0.215 m/s2 (CRT 36-24A) and 0.316 m/s2 (CRT 36-

25).

-for hand/arm: 1.81 m/s2 (CRT 36-24A) and 1.72 m/s2 (CRT 36-25).

The sound and vibration specifications were obtained with the unit

operating on fully cured, water wetted concrete at nominal engine

speed.
