varying with time.
The measurement time shall be as long as
reasonably possible and normally not less than 8
s for hand-transmitted vibration measurements.
If the measurement time of 8 s for individual
machines is not possible, e.g. because of short
duration of operation (defined in 13.3.6.3), this
shall be specified in the relevant Part 2 of this
standard.
13.3.4.4 Combination of vibration directions
N/A
The vibration total value a
hv
is determined from
Where
a
hwx,
a
hwy,
a
hwz
are the r.m.s. values of the
frequency-weighted acceleration in the directions
X, Y and Z, respectively
N/A
13.3.5 Instrumentation requirements
N/A
13.3.5.1 General
N/A
The vibration measurement equipment shall be in
accordance with EN ISO 8041.
Instrumentation for measuring other parameters
(e.g. for controlling the working conditions),
whose characteristics are not covered by EN ISO
8041, shall be specified in the relevant Part 2.
N/A
13.3.5.2 Transducers
N/A
13.3.5.2.1
Specification of transducers
N/A
The vibration values as specified in 13.3.4.3 shall
be measured using transducers and other
appropriate measurement equipment conforming
to EN ISO 8041.
The total mass of the vibration transducer and its
mounting shall not be sufficient to influence the
measurement result and shall not be more than 5
g for each direction of measurement.
NOTE Lightweight plastic handles are an example,
where heavy transducers may not be suitable. See EN
ISO 5349-2 for further information.
Factors such as the transverse sensitivity {less
than 10 %), the ambient temperature range, the
typical temperature transient sensitivity and the
