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 auf 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 definieren.
Dieses Dokument gilt nicht für Messeinrichtungen, die für die Messung oder Protokollierung der Einwirkungs¬dauer ausgelegt sind, ohne gleichzeitig eine Schwingungsmessung durchzuführen. Messeinrichtungen dieser Art werden in ISO/TR 19664 beschrieben.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

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.

DRAFT INTERNATIONAL STANDARD ISO/DIS 8041-2:2020(E)
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.
