Human response to vibration - Measuring instrumentation (ISO 8041:2005)
ISO 8041:2005 specifies the performance specifications and tolerance limits for instruments designed to measure vibration values, for the purpose of assessing human response to vibration. It includes requirements for pattern evaluation, periodic verification and in-situ checks, and the specification of vibration calibrators for in-situ checks.
Vibration instruments specified in ISO 8041:2005 can be single instruments, combinations of instrumentation or computer-based acquisition and analysis systems.
Three levels of performance testing are defined in ISO 8041:2005: pattern evaluation, i.e. a full test of the instrument against the specifications defined in this International Standard; periodic verification, i.e. an intermediate set of tests designed to ensure that an instrument remains within the required performance specification, and in-situ checks, i.e. a minimum level of testing required to indicate that an instrument is likely to be functioning within the required performance specification.
Schwingungseinwirkung auf den Menschen - Messeinrichtung (ISO 8041:2005)
Diese Internationale Norm spezifiziert die Leistungsmerkmale und die Fehlergrenzen von Messeinrichtungen, die die Schwingungen zum Zwecke der Beurteilung der Schwingungseinwirkung auf den Menschen messen. Sie enthält auch Vorgaben für die Baumusterprüfung, die periodische Nachprüfung (Einzelprüfung) und die Prüfung am Einsatzort sowie die Spezifikation von Schwingungskalibratoren für die Prüfung am Einsatzort.
Die in dieser Internationalen Norm spezifizierten Schwingungsmesseinrichtungen können Kompaktgeräte,
aus einzelnen Geräten zusammengesetzte Messsysteme oder rechnergestützte Datenerfassungs- und auswertungssysteme sein.
Die in dieser Internationalen Norm spezifizierten Schwingungsmesseinrichtungen dienen zur Messung der Schwingungen auf einem oder mehreren der folgenden Anwendungsgebiete:
- Hand-Arm-Schwingungen (siehe ISO 5349-1),
- Ganzkörper-Schwingungen (siehe ISO 2631-1, ISO 2631-2, ISO 2631-4),
- tieffrequente Ganzkörper-Schwingungen im Frequenzbereich von 0,1 Hz bis 0,5 Hz (siehe ISO 2631-1).
Die Schwingungsmesseinrichtungen können zur Messung mit einer oder mehreren der Frequenzbewertungen ausgelegt sein, die für diese Anwendungsgebiete jeweils definiert sind.
In dieser Internationalen Norm werden drei Stufen von Prüfungen festgelegt:
a) Baumusterprüfung, d. h. eine umfassende Prüfung, ob die Messeinrichtung die in dieser Internationalen Norm festgelegten Spezifikationen erfüllt;
b) periodische Nachprüfung, d. h. eine Zwischenprüfung reduzierten Umfangs zur Sicherstellung, dass die Messeinrichtung die geforderten Spezifikationen weiterhin einhält;
c) Prüfung am Einsatzort, d. h. eine überschlägige Prüfung, die aussagt, ob die Messeinrichtung in dem spezifizierten Bereich ihrer Leistungsmerkmale richtig funktioniert.
Réponse des individus aux vibrations - Appareillage de mesure (ISO 8041:2005)
L'ISO 8041:2005 donne les spécifications de performances et les limites de tolérance pour les instruments destinés à mesurer les valeurs de vibration afin d'évaluer la réponse des individus aux vibrations. Elle inclut les exigences relatives aux essais de conformité, à la vérification périodique et aux contrôles in-situ, ainsi que la spécification concernant les calibrateurs de vibration destinés aux contrôles in-situ.
Les instruments de mesure des vibrations spécifiés dans l'ISO 8041:2005 peuvent être des instruments simples, des combinaisons d'instruments ou des systèmes d'acquisition et d'analyse informatisés.
Trois niveaux de vérification des performances sont définis dans l'ISO 8041:2005: les essais de conformité, c'est-à-dire un essai complet de l'instrument par rapport aux spécifications définies dans la présente Norme internationale; la vérification périodique, c'est-à-dire un ensemble intermédiaire d'essais destiné à s'assurer qu'un instrument donné relève effectivement de la spécification de performances requise, et contrôles in-situ, c'est-à-dire un niveau minimal de vérification à appliquer pour indiquer que le fonctionnement d'un instrument donné relève vraisemblablement de la spécification de performances requise.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 8041 was prepared by Technical Committee ISO/TC 108, Mechanical vibration and shock, Subcommittee
SC 3, Use and calibration of vibration and shock measuring instruments.
This second edition cancels and replaces the first edition (ISO 8041:1990), which has been technically
revised, and incorporates its Amendment, ISO 8041:1990/Amd.1:1999, and Technical Corrigendum
ISO 8041:1990/Cor.1:1993.
The reasons for the main changes introduced in this edition are as follows:
to improve the specifications for human response to vibration measuring instrumentation;
to incorporate into one document the specifications introduced by the 1999 amendment to ISO 8041:1990,
which themselves were required following the introduction of new frequency weightings in
ISO 2631-1:1997;
to recognise changes in the frequency weighting specification introduced in ISO 5349-1:2001 that allows
frequencies outside the one-third octaves from 6,3 Hz to 1250 Hz to be excluded from the weighted
acceleration calculation (this is achieved by changing the frequencies at which the tolerance is extended
to −100 % to be the lower boundary of the 6,3 Hz one-third-octave bands and the upper boundary of the
1 250 Hz one-third-octave band);
to introduce allowances for the uncertainties of testing the conformance of the human vibration measuring
instruments;
to introduce a hierarchy of testing requirements (pattern evaluation, periodic verification and in-situ check)
with tests defined according to the needs of this hierarchy;
to recognise the needs for the specification and testing of new parameters such as maximum transient
vibration value (MTVV) and vibration dose value (VDV);
to recognise the need to test multi-axis instrumentation and to test combined results from these multi-axis
inputs;
to introduce informative tests for mounting methods.

INTERNATIONAL STANDARD ISO 8041:2005(E)
Human response to vibration — Measuring instrumentation
1 Scope
This International Standard specifies the performance specifications and tolerance limits for instruments
designed to measure vibration values, for the purpose of assessing human response to vibration. It includes
requirements for pattern evaluation, periodic verification and in-situ checks, and the specification of vibration
calibrators for in-situ checks.
Vibration instruments specified in this International Standard can be single instruments, combinations of
instrumentation or computer-based acquisition and analysis systems.
Vibration instruments specified in this International Standard are intended to measure vibrations for one or
more applications, such as
hand-transmitted vibration (see ISO 5349-1),
whole-body vibration (see ISO 2631-1, ISO 2631-2, ISO 2631-4), and
low-frequency whole-body vibration in the frequency range from 0,1 Hz to 0,5 Hz (see ISO 2631-1).
Vibration instruments can be designed for measurement according to one or more of the frequency weightings
defined within each of these applications.
Three levels of performance testing are defined in this International Standard:
a) pattern evaluation, i.e. a full test of the instrument against the specifications defined in this International
Standard;
b) periodic verification, i.e. an intermediate set of tests designed to ensure that an instrument remains within
the required performance specification, and
c) in-situ checks, i.e. a minimum level of testing required to indicate that an instrument is likely to be
functioning within the required performance specification.
