Human response to vibration - Measuring instrumentation - Part 2: Personal vibration exposure meters (ISO 8041-2:2021)
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 (according to ISO 2631-1, ISO 2631-2 and ISO 2631-4) and/or
hand-arm vibration (according to 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.
This document does not 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.
Schwingungseinwirkung auf den Menschen - Messeinrichtung - Teil 2: Messgeräte für die personenbezogene Schwingungseinwirkung (ISO 8041-2:2021)
Dieses Dokument legt Mindestanforderungen an Messgeräte für die personenbezogene Schwingungs-einwirkung fest.
Dieses Dokument ist anwendbar für Messeinrichtungen, die für die Messung von Ganzkörper-Schwingungen im Rahmen der Arbeitshygiene (nach ISO 2631 1, ISO 2631 2 und ISO 2631 4) und/oder Hand-Arm-Schwingungen (nach ISO 5349 1) zusammen mit den zugehörigen Expositionszeiten ausgelegt sind.
Dieses Dokument enthält Festlegungen zu Sollwerten und zulässigen Grenzabweichungen, die die Mindest-leistungsfähigkeit und die funktionellen Anforderungen von Messeinrichtungen zur Messung der täglichen personenbezogenen Schwingungseinwirkung festlegen.
Dieses Dokument ist nicht anzuwenden für Messeinrichtungen, die für die Messung oder Protokollierung der Einwirkungsdauer ausgelegt sind, ohne gleichzeitig eine Schwingungsmessung durchzuführen. Messeinrichtungen dieser Art werden in ISO/TR 19664 beschrieben.
Réponse des individus aux vibrations - Appareillage de mesure - Partie 2: Instrument de mesure de l'exposition des personnes aux vibrations (ISO 8041-2:2021)
Le présent document spécifie les exigences minimales applicables aux instruments de mesure de l’exposition des personnes aux vibrations (IMEPV).
Le présent document est applicable aux instruments conçus pour les mesurages des vibrations globales du corps dans le cadre des applications d’hygiène industrielle (conformément à l’ISO 2631-1, l’ISO 2631-2 et l’ISO 2631-4) et/ou des vibrations main-bras (conformément à l’ISO 5349-1) avec les durées d’exposition associées.
Le présent document fournit les objectifs de conception spécifiques et les tolérances admissibles qui définissent les capacités de performance minimales et les exigences fonctionnelles des instruments conçus pour mesurer l’exposition quotidienne des personnes aux vibrations.
Le présent document ne s’applique pas aux instruments conçus pour mesurer ou enregistrer les durées d’exposition sans réaliser également de mesurage des vibrations. Les instruments de ce genre sont décrits dans l’ISO/TR 19664.

Introduction
ISO 8041-1 specifies instruments for the measurement of vibration to which human beings are exposed.
These instruments are used for temporary, short-time measurements or controlled measurements.
The present document specifies personal vibration exposure meters, shortly PVEM, to measure human
exposure to vibration over long time periods, e.g. a whole working shift.
PVEM need not to fulfil all the specifications given in ISO 8041-1. On the other hand, they need to fulfil
other requirements to allow none-controlled measurements or stand-alone measurements over longer
time periods. In combination with alarm functions, they can be capable to inform the user before the
vibration exposure reaches certain values (action value, limit value). This fact makes it necessary to
distinguish PVEM from the instrumentation specified in ISO 8041-1.
Annexes B and C describe possible extension features with additional information for the measurement
procedure.

Human response to vibration — Measuring
instrumentation —
Part 2:
Personal vibration exposure meters
1 Scope
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.
