Clause
shall be made as a dual number noise emission
declaration according to EN ISO 4871.
13.3 Vibration
13.3.1 Vibration reduction
The vibration at the handles shall be kept as low
as possible without unduly affecting the
performance and the ergonomics (weight,
handling, etc.) of the tool.
In particular vibration shall be reduced by the
application of engineering measures as given in
CR 1030-1. The success of the applied vibration
measures is assessed by comparing the
vibration levels for the tool with those for other
tools of the same type and with a comparable
specification and performance.
13.3.2 Vibration measurement - General
Details for particular types of tools are given in
the relevant Part 2. The test code gives all the
information necessary to carry out efficiently the
determination, declaration and verification of the
vibration emission characteristics for tools which
are hand-guided or hand-operated. It shall allow
comparison of test results for different tools.
The vibration total value may be determined by
using the measurements from a machine which
has design and technical specifications
replicating the machine concerned.
EN 12096 gives guidance on how to declare the
vibration total values of machinery, and
specifies requirements for verification of
declared values.
The vibration levels for hand-arm vibration ah to
be quoted in the user instructions, as required
by 7.13 za) 3 shall be measured in accordance
with the following test procedure.
The uncertainty K is provided as an indication of
the measured deviation from the mean during
the test.
The measurement and assessment of human
exposure to hand-transmitted vibration in the
workplace is given in EN ISO 5349-1 and EN
ISO 5349-2.
NOTE Annex ZC provides information on possible
sources of errors of measurement.
