Noise emission values
According to DIN EN ISO 11202 supplemented by CEN -TC 142, the
workplace emission value L
pA
amounts to:
idle running
.......... dB(A)
Working noise 84.5 dB(A)
According to EN ISO 3746 supplemented by CEN -TC 142, the
sound power level L
WA
amounts to:
Idle running ...........dB(A)
Working noise 94.7 dB(A)
The measurement uncertainty constant K amounts to 4 dB(A).
The following supplements specified by CEN - TC142 in order to achieve an accuracy
class better than 3 dB were taken into consideration:
– The environmental corrective factors K
2A
and K
3A
amount to
≤
4 dB.
– The difference between the foreign noise sound pressure level and the noise sound
pressure level at all measuring points is
≥
6 dB.
– K
3A
is calculated according to appendix A, DIN EN ISO 11204.
– A rectangular enveloping measurement surface with 9 measuring points of
1.0 m from the reference surface is used.
Under consideration of ISO 7960 sections 0 to 4, the machine-specific conditions of
measurement were as follows:
Drill bit: 1x concealed hinge drill bit d=35mm; t=13mm n=2750 min
-1
2x dowel drill bits d= 8mm; t=13mm n=2750 min
-1
Workpiece: Uncoated chipboard
Microphone position: 1m distance form the centre of the bore axis at a height of 1.5m.
Note
The values given here are emission values and may not simultaneously represent safe
working area values. As there is no correlation between emission values and working
area values, these cannot be reliably used in order to determine whether or not
additional precautions are required. Factors which could affect the current working
area values include the duration of the influence, the characteristics of the working
space, other sources of noise, the number of machines and other neighbouring
influences. The reliable working area values can also vary from one country to another.
However, this information should enable the operator to make a better estimation of
the potential hazards and risks.
3.3. Machine identification
The machine is equipped with a type plate which details the following:
– machine type
– machine number
– year of manufacture
– weight
– the required compressed air.
