Test Report No.: No.: 17706687 001
Part II of II
Requirement Test
Clause
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
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.
13.3.7
Measurement procedure and validity
13.3.7.1
Reported vibration value
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
total values a
than 0,15 or the standard deviation s
than 0,3 m/s
provides information on possible sources of
errors of measurement).
The measurement result a
as the arithmetic mean of vibration total values
over the tests and operators.
13.3.7.2
Declaration of the vibration total value
The result a
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.
