7.4 Sound and Vibration Measurements
The required sound specification, Paragraph 1.7.4.f of 89/392/EEC
Machinery Directive, is:
the sound pressure level at operator’s location (L
pA
) = 95 dB(A)
the guaranteed sound power level (L
WA
) = 108 dB(A).
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, is approximately:
Hands = 9.66 m/s

.
The sound and vibration measurements were obtained with the
machine operating on hard asphalt at maximum RPM and top speed.
HAV Uncertainties
Hand-transmitted vibration was measured per ISO 5349-1. This
measurement includes an uncertainty of 1.5 m/sec
