This document specifies minimum requirements for personal vibration exposure meters (PVEM). This document is applicable to instruments designed for measurements of whole-body vibration in the context of industrial hygiene applications (in accordance with ISO 2631-1, ISO 2631-2 and ISO 2631-4) and/or hand-arm vibration (in accordance with ISO 5349-1) together with the associated exposure times. This document provides specified design goals and permitted tolerances that define the minimum performance capabilities and functional requirements of instruments designed to measure personal daily vibration exposure. Instruments meeting the requirements of this document are required to have logging capabilities. Additional information is provided on how instruments might use the logged data for post-processing, e.g. to identify transient acceleration artefacts in the measurement so that they can be excluded from vibration exposure values and the evaluation of accurate vibration exposure times. NOTE This document is not intended to apply to instruments designed to measure or log exposure times without also performing vibration measurement. Instrumentation of this type is described in ISO/TR 19664.
