TECHNICAL SPECIFICATIONS SECTION 7
DD-29/31HF/38HF Vibratory Asphalt Compactors 7-5
DD-38HF
Noise Emission
In accordance with the requirements of clause 1.7.4 (f) of Annex 1 of Council
Directive...Relating to Machinery 98/37/EC, the following values were measured:
Equivalent continuous A-weighted sound pressure level at operator’s station:
(Leq) = 81 dB(A) Engine Only: 87 dB(A) Vibration ON. Units with cab: (N.A.) dB(A) Engine
Only; (N.A.) dB(A) Vibration ON.
Guaranteed Maximum A-weighted sound power level of the machine: (Lw) = (109) dB(A)
Vibration ON.
These measurements were recorded in accordance with ISO 6394, ISO 6396 and
ISO 6395 with engine at manufacturer's rated speed.
Operator's Exposure to Vibration
In accordance with the requirements of clause 3.6.3 (a) of Annex 1 of Council
Directive...Relating to Machinery 98/37/EC, the following values were measured:
Arms/hands: The weighted root mean square acceleration value to which the hands are
subjected: (Aeq) does not exceed 4.69 m/s².
Body/posterior: The weighted root mean square acceleration value to which the posterior
is subjected: (Aeq) does not exceed 0.13 m/s².
These measurements were recorded in accordance with ISO 5349 and ISO 2631 with the
machine operating at maximum vibration amplitude and maximum frequency.
