ISO/TR 10687:2012
Mechanical vibration— Description and determination of seated postures with reference to whole-body vibration
ISO/TR 10687:2012 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.
Additionally, ISO/TR 10687:2012 deals with dynamic postures where body angles or associated movements are determined visually or by measuring points on the skin or clothing.
ISO/TR 10687:2012 does not recommend sampling strategies or evaluation methods.
