1 Scope
This Technical Report summarizes descriptive quantities for those responsible (e.g.
scientists, safety engineers) for determination of postures for a seated person who
is exposed to whole-body vibration. It is the intention that the results of different
methods which also are summarized can be easily related to these quantities and that
they allow for a common terminology between practitioners. The postures determined
can also be used as a basis for further investigation or as a means of comparison
for different methods. Although some of the approaches described here can be applied
to standing or recumbent positions, additional considerations are likely to be required
in these cases.
NOTE 1 This work is closely related to International Standards which focus on static postures
(ISO 11226[4]) or on radiologically accessible landmarks, i.e. points on the body (ISO 8727[3]).
Additionally, this Technical Report deals with dynamic postures where body angles
or associated movements are determined visually or by measuring points on the skin
or clothing.
NOTE 2 Nevertheless, ISO 8727[3] and ISO 11226[4] put forward principles for further extensions which are followed in this Technical
Report, in particular for measurements of body angles.
This Technical Report does not recommend sampling strategies or evaluation methods.
