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

Add the following Introduction:
ISO/DIS 8041:2015(E)
Human response to vibration — Measuring
instrumentation
AMENDMENT 1
Introduction
Up to 2005, when this International Standard 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 e.g. IEPE and MEMS transducers.
Some of the test procedures specified in this International Standard, 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 signals. 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 International Standard.
Some of the test procedures specified in this International Standard can only be performed if an
electrical output is available, e.g. 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 signals.
The verification test specified in this Amendment is practicable and has the objective of identifying
an instrument which is adequately calibrated for the intended applications and is suitable for the
purpose, at a cost reasonable for the calibration laboratory and affordable for the end user. Therefore
the verification test is strongly reduced in its extend compared to the full pattern evaluation or
validation and does only test the most relevant characteristcs of a vibration meter.

Add after pattern evaluation “or validation”.
Renumber a) to be a1) and add the following:

system against the relevant specifications defined in this International Standard;

Add at the end of the subclause the following Note:
NOTE — It is useful that the vibration meter is capable of indicating how long (in relation to the
measurement duration) in each channel an overload took place.
Page 19, 5.16
Add at the end of the subclause the following Note:
NOTE — This electrical cross-talk between measurement channels should be distinguished
from transducer transverse sensitivity which typically is greater than 0,5 %, see Clause E.2. The
transverse sensitivity can become relevant especially with multi-axial transducers.
Page 23, Clause 11
Replace a) by the following:
a1) Pattern evaluation (targeted at manufacturers) is a full set of tests to be performed on samples of
an instrument type. This test is used for product type testing or pattern approval of a production
series of vibration measuring instruments. The objective of this test is to demonstrate an instrument
design can meet the specifications defined in this International Standard;
a2) Validation of one-off instruments (targeted at laboratory users or research users) is a limited set
of tests to demonstrate that an individual vibration measuring system complies with the relevant
specifications defined in this International Standard;
Replace in b), first indent, “every 1 or” by “at least every”.
Delete in b) the second indent.
Add in b) in the last indent after modification “(e.g. use of another transducer)”.

Add the following second and third paragraphs:
The instrument shall be submitted for testing with equipment (e.g. adaptors) suitable for enabling the
input and output of electrical signals.
A vibration calibrator should be supplied with the vibration instrument.

Replace the second sentence by “The instrument, transducer and the vibration calibrator (if supplied)
shall be visually inspected and all controls operated to ensure they are in working order.”
Page 26, 12.7
Replace the third paragraph by the following:
The reference vibration transducer shall be used to measure the value of the mechanical vibration
input generated at the reference vibration value and at the reference frequency, before measuring the
vibration magnitude with the vibration meter. For these measurements, the vibration meter shall be set
to the reference measurement range, band-limiting frequency-weighting and linear time averaging and
with a measurement duration sufficient for the indicated values to stabilize (for low-frequency testing,
this duration can be as much as 30 s for hand-arm vibration, 1 min for whole-body, and 5 min for low-
frequency whole-body applications). The value of the input signal plus background noise shall be at least
10 times the value of the background noise as measured by the vibration meter.

Replace the second paragraph by the following:
At the reference frequency, the input mechanical vibration shall be adjusted such that the indication
of band-limited vibration on the instrument under test is 20 dB above the lower limit of the specified
, shall be used as a
linearity range. The band-limited acceleration value of this input signal, a
