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

ISO 8041-1:2017(E)
Introduction
Until 2005, when the previous edition of this document was published, measuring instrumentation
for human response to vibration (vibration meters) normally consisted of a signal processing unit
and a detachable vibration transducer. According to recent developments, however, part of the
signal processing steps can be integrated in the transducer unit, so that the signal coming out of the
transducer’s sensing element and going into the signal conditioning unit is not accessible any more.
These transducer units include, for example, IEPE and MEMS transducers.
Some of the test procedures specified in this document, however, presume that this point in the signal
path is accessible (electrical input). Since such an input is not mandatory these tests can only be
performed on a vibration meter having an electrical input or after some technical modifications to the
instrumentation, e.g. internal access to signal paths. Or those tests can only be performed mechanically,
which in certain cases requires modifications to some test procedures. Such modifications to test
procedures, however, are beyond the present scope of this document.
Some of the test procedures specified in this document can only be performed if an electrical output
is available, see for example 5.13. Since such an output is not mandatory these tests can only be
performed on a vibration meter having an electrical output or after some technical modifications to the
instrumentation, e.g. internal access to signal paths.
The verification test now specified in this document is practicable and has the objective of identifying an
instrument which is adequately calibrated for the intended applications and is suitable for its purpose,
at a cost reasonable for the calibration laboratory and affordable for the end user. Therefore, the
verification test is strongly reduced in its extent compared to the full pattern evaluation, or validation,
and only tests the most relevant characteristics of a vibration meter.
INTERNATIONAL STANDARD ISO 8041-1:2017(E)
Human response to vibration — Measuring
instrumentation —
Part 1:
General purpose vibration meters
1 Scope
This document 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, or validation, periodic verification and in situ checks, and the
specification of vibration calibrators for in situ checks.
Vibration instruments specified in this document can be single instruments, combinations of
instrumentation or computer-based acquisition and analysis systems.
Vibration instruments specified in this document are intended to measure vibration for one or more
applications, such as the following:
— hand-transmitted vibration (see ISO 5349-1);
— whole-body vibration (see ISO 2631-1, ISO 2631-2 and ISO 2631-4);
— 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 document:
a) pattern evaluation or validation:
1) pattern evaluation, i.e. a full test of the instrument against the specifications defined in this
document;
2) validation of one-off instruments, i.e. a limited set of tests of an individual vibration measuring
system against the relevant specifications defined in this document;
b) periodic verification, i.e. an intermediate set of tests designed to ensure that an instrument remains
within the required performance specification;
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.
