Clause Requirement Remarks - Results Verdict
g) environmental indicator K
2A
and local environmental
factor K
3A
shall be equal to or less than 4 dB;
h) difference between the background emission sound
pressure level and the workstation sound pressure
level shall be equal to or greater than 6 dB in
accordance with EN ISO 11202:2010, 6.4.1, accuracy
grade 2 (Engineering);
i) correction of the local environmental factor
K
3A
shall be
calculated in accordance with A.2 of EN ISO
11204:2010 with reference restricted to EN ISO
3746:2010 instead of the method given in Annex A of
EN ISO 11202:2010 or in accordance with EN ISO
3743-1:2010, EN ISO 3743-2:2009, EN ISO 3744:2010
or EN ISO 3745:2012 where one of these standards
has been used as the measuring method.
For noise declaration 6.3 dd) shall be met.
5.4.2.2.2 Noise emission measurement for building site saws N/A
Emission sound power levels of building site saws shall
be measured as follows:
a) basic noise emission standard EN ISO 3744:2010 shall
be used;
b) operating conditions shall comply with A.2 b) in Annex
A of ISO 7960:1995;
c) measurement surface, number of microphone positions
and measuring distance shall comply with Annex A of
ISO 7960:1995;
d) surface sound pressure level shall be determined at
least three times. If at least two of the determined
values do not differ by more than 1 dB, further
measurements will not be necessary; otherwise the
measurements shall be continued until two values
differing by no more than 1 dB are obtained. The A-
weighted surface sound pressure level to be used for
calculating the sound power level is the arithmetic
mean of the two highest values that do not differ by
more than 1 dB.
N/A
Emission sound pressure levels at the workstation shall
be measured in accordance with EN ISO 11202:2010 with
the following modifications:
e) environmental indicator
K
2A
and local environmental
factor K
3A
shall be equal to or less than 4 dB;
