Ehdotuksen tiedot

This document 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. This document specifies a methodology for assessing the health risk of individuals exposed to whole-body vibration (WBV) that includes the addition of posture effects. This document defines an accumulative posture index that is applied to the daily overall frequency-weighted root-mean-square (r.m.s.) acceleration to establish a combined daily vibration exposure for assessing health risk.  This document is limited to the seated person subjected to WBV and health risk assessment using the ISO/DIS 2631-1 [1] basic evaluation method. It does not apply to standing or recumbent (supine) persons. This document does not include regional lumbar support or measurement of lumbar lordosis verses lumbar kyphosis. This document does not consider transient vibration or regular or occasional shocks.
