scope:

Specifies anatomical and basicentric coordinate systems for biodynamical measurements, for reference purposes in cognate standards development, and for precisely describing human exposure to mechanical vibration and shock. The segmental anatomical coordinate systems defined in this standard are for the head, root of the neck (driving-point for the head and neck system), pelvis, and hand. General principles are stated for the establishment of corresponding anatomical coordinate systems for other skeletal body segments. The biodynamic coordinate systems defined in this standard can serve as frames of reference for the description and measurement of both translational and rotational vibration and shock motion affecting humans.
