5.4 Emissions
5.4.1 Noise - characteristic values
The noise emission values determined according to DIN EN ISO 3746 for the
sound power level or DIN EN ISO 11202 and for the sound pressure level at
the workplace on the basis of the working conditions stated in ISO 7960 Appen
-
dix A are as listed in the table.
A measurement uncertainty allowance of K = 4 dB (A) applies to the stated
emission values.
The specified values are emission values and cannot be taken as reliable val
-
ues for each workplace. Although there is a correlation between emission and
immission levels, it is not possible to reliably deduct if additional precautionary
measures are required or not. Factors, which influence the current actual im
-
mission level at the workplace include the individual conditions in the working
space and other noise sources, i.e. the number of machines and other operat
-
ing processes in the vicinity. The admissible workplace values are different in
each country. However, this information should support the owner/user to as
-
sess hazards and risks.
The measured values apply to derived timber products. Deviating values are
possible when aluminium profiles are processed.
5.4.2 Dust
The dust emission values – measured in accordance with the “Principles for
Testing Dust Emission (Concentration Parameters) from Woodworking Ma
-
chines” issued by the German trade association's technical committee for wood
– are below 2 mg/m
3
.
When the machine is attached to a correctly functioning extraction system with
an air speed of at least 20 m/s (measured after joining the two extraction con
-
nections) you can assume it is and will stay compliant with the technical refer
-
ence concentration (TRK) limit for wood dust that is in force in Germany.
The machines are tested concerning wood dust in accordance with the BGI
739-1. The machines bear the DGUV mark with the additional wood dust mark
"holzstaubgeprüft". Consequently, a company operating the machine in Ger
-
many is exempt from the obligation to perform measurements at the workplace
in accordance with TRGS 553.
