Test Result - Remark Verdict
typical and normal use of the machine under test.
The measurement may be carried out by
processing a work piece or under external
mechanical load equivalent to normal operation.
Before starting the test, the tool shall be operated
under these conditions of at least 1 min to warm it
up.
13.3.6.4 Operator
N/A
The vibration of the machine is influenced by the
operator. The operator shall therefore be skilled
and able to operate the machine properly, i.e. he
shall be experienced in the use of the tool.
The gripping force shall be as under long term
working conditions and not be excessive.
N/A
13.3.7 Measurement procedure and validity
N/A
13.3.7.1 Reported vibration value
N/A
Three series of five consecutive tests shall be
carried out using a different operator for each
series. If it can be shown that the vibration is not
affected by operator characteristics, it is
acceptable to perform all 15 measurements with
one operator only. Details are specified in the
relevant Part 2.
The measurements are made in three axes and
the results of each direction shall be combined
using equation (Z1) to obtain the vibration total
value
a
hv
.
If the coefficient of variation C
v
of the five vibration
total values a
hv
, recorded for each series, is les
than 0,15 or the standard deviation s
N-1
is less
than 0,3 m/s
2
, the results are accepted (Annex 2
provides information on possible sources of
errors of measurement).
The measurement result a
h
shall be determined
as the arithmetic mean of vibration total values
over the tests and operators.
N/A
13.3.7.2 Declaration of the vibration total value
N/A
The result a
h
is the basis for the declared value. If
values have been obtained for different hand
positions, the greatest value shall be the basis for
the declaration.
If required by the relevant Part 2, the work mode
description corresponding to the vibration
emission shall be stated next to each declared
value.
