Test Report No.: 17702074 003
Part I of II
g) environmental indicator K2A and local environmental
factor K3A 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 K3A 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.
Noise emission measurement for building site saws
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.
Emission sound pressure levels at the workstation shall
be measured in accordance with EN ISO 11202:2010 with
the following modifications:
e) environmental indicator K2A and local environmental
factor K3A shall be equal to or less than 4 dB;
