Test Result - Remark Verdict
13.2.1 Noise reduction P
Noise reduction at tools is an integral part of the
design process and shall be achieved by
particularly applying measures at source to
control noise, see for example EN ISO 11688-1.
The success of the applied noise reduction
measures is assessed on the basis of the actual
noise emission values in relation to other
machines of the same family with comparable
non acoustical technical data.
The major sound sources of tools are given in
the relevant Part 2.
P
13.2.2 Noise emission measurement (general) P
Noise emission values like the emission sound
pressure level LpA and the sound power level
LWA to be quoted in the user instructions as
required by 7.13 shall be measured by the test
procedure described in 13.2.3 to 13.2.6. P
The overall noise emitted is influenced by both
the process noise and method of operation. The
load conditions for particular tools are therefore
specified in the relevant Part 2. P
The noise emission values obtained under the
measurement conditions described in this
standard will not necessarily correspond to the
diverse noise levels produced under the
operational conditions of practical use. P
13.2.3 Instrumentation and preparation of test samples P
The instrumentation for the measurement of
acoustic values shall be in accordance with
EN lSO 3744.
P
Sound level meters shall comply with the
requirements of IEC 60651 Type 1 and shall be
used with frequency weighting "A" and response
level "S". P
Measurements shall be carried out on a new
tool, additional to that required by other tests. P
All speed setting devices shall be adjusted to
the highest figure. P
Tools shall be run-in for a period of 5 min before
starting test. The supply voltage of mains
powered tools is measured at the plug of the
cable or cord supplied, not at the plug of any
extension cable or cord. P
