| Resumen: | This document addresses human exposure to multiple mechanical shocks, and it formulates requirements for the measurement of multiple shocks. The results of these measurements are then analyzed to provide information for the assessment of the risk of adverse health effects to the vertebral end-plates of the lumbar spine for seated individuals due to compression. Other injuries could develop even when there is no injury to the end plate. Two exposure regimes are distinguished in this document: one for severe conditions and one for less severe conditions. This document is applicable for unweighted vertical accelerations that have peak values up to 137,3 m/s2 (14 g) measured at the seat-occupant interface beneath the ischial tuberosities over a 0,01 Hz to 80 Hz measurement bandwidth. Caution is necessary when applying the method to severe exposures, particularly since peak accelerations of 137,3 m/s2 (14 g) are close to the physical limit that a spine can tolerate. |
