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).

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.
