Overview

EN ISO 5349-2:2001/A1:2015 (ISO 5349-2:2001/Amd 1:2015) is the CEN-adopted amendment to Part 2 of ISO 5349, providing practical guidance for measurement of hand-transmitted vibration at the workplace. It complements ISO 5349-1 (general requirements) by describing how to carry out reliable vibration measurement for assessment of human exposure to hand–arm vibration in real work settings. The amendment updates normative references and clarifies measurement location, mounting and instrumentation guidance.

Key topics and technical requirements

• Measurement objective: Record representative vibration entering the hand to support evaluation of worker exposure and risk management.
• Frequency range and instrumentation: Measurements cover one‑third‑octave band mid-frequencies from 6.3 Hz to 1 250 Hz; accelerometers must cope with very high peak magnitudes (example: pneumatic tools can generate extremely high accelerations) while still responding accurately in the specified frequency band.
• Accelerometer location: Preferably at the middle of the gripping zone where vibration enters the hand; when not possible, mount on either side of the hand or on the handle underside. For side‑mounted handles, using two accelerometers and averaging is recommended.
• Mounting and coupling: Transducers must be rigidly attached with a mounting system that has a flat frequency response across the measurement band, no structural resonances, and minimal interference with normal operation. Check mountings before and after measurement.
• Resilient coatings: When handles have soft coatings, either remove the material under the transducer, fully compress it during mounting (hose clamp), or use an adaptor held by the operator’s normal grip to better reflect transmitted vibration. Note: poorly selected coatings can amplify certain frequencies.
• Reporting: Document measurement locations, orientations, mounting method and any adaptors used to ensure traceability and comparability.

Practical applications and users

• Occupational hygienists and safety engineers assessing hand‑arm vibration exposure and implementing control measures.
• Test laboratories and vibration analysts performing workplace measurements to support compliance and risk assessments.
• Manufacturers of hand‑held tools and PPE designers validating handle designs and vibration‑reduction measures.
• Health & safety compliance officers and ergonomists using measured data to inform exposure reduction, training and tool selection.

Related standards

• ISO 5349-1 - General requirements for measurement and evaluation of hand‑transmitted vibration.
• ISO 8041 - Instrumentation for human response to vibration.
• ISO 22867, ISO 28927 series - Vibration emission test codes and test methods for hand‑held machinery (measurement locations and laboratory emission testing).

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).

Replace the subclause with the following.
6.1.2.2 Vibration magnitude
Hand-held machines can produce high vibration magnitudes. A pneumatic hammer, for example, can
2 2
generate a maximum acceleration of 20 000 m/s to 50 000 m/s . However, much of this energy is at
frequencies well outside the frequency range used in this part of ISO 5349. Therefore, the accelerometer
chosen for the measurement has to be able to operate at these very high vibration magnitudes and
yet still respond to the much lower magnitudes in the frequency range from 6,3 Hz to 1 250 Hz (one-
third-octave band mid-frequencies). For the use of mechanical filters to suppress vibration at very high
frequencies, see Annex C.
Page 7, 6.1.3
Replace the subclause with the following.
6.1.3 Location of accelerometers
Vibration measurements in accordance with ISO 5349-1 should be made at or near the surface of the
hand (or hands) where the vibration enters the body. Preferably, the accelerometer should be located
ISO 5349-2:2001/Amd.1:2015(E)
at the middle of the gripping zone (e.g. halfway along the width of the hand when gripping a machine
handle), it is at this location that the most representative evaluation of the vibration entering the hand
is obtained. However, it is generally not possible to locate transducers at this point; the transducers will
interfere with the normal grip used by the operator.
Measurements directly under the hand are usually only possible using special mounting adaptors
(see Annex D). Such adaptors should fit under the hand, or between the fingers. For most practical
measurements, the accelerometers are mounted on either side of the hand or on the underside of the
machine handle adjacent to the middle of the hand. With adaptors that fit between the fingers, the
transducers should be mounted as close as possible to the surface of the machine handle to minimize
amplification of rotational vibration components. They should not have any structural resonances that
would affect the measured vibration.
It is possible to get differences in vibration measurement across the width of the hand, particularly for
hand-held machines with side handles, such as angle grinders, and especially where these handles are
flexibly mounted. In these cases, it is recommended that two accelerometers positions be used, located
one on each side of the hand; the average of the two vibration measurements is then used to estimate
vibration exposure.
For many hand-held machines, specific measurement locations and axes have been defined for the
measurement of vibration emission by ISO 22867, ISO 28927, and other International Standards for
declaration of vibration emission; these measurement locations are summarized in Annex A as examples
of measurement locations. The measurement locations defined in vibration emission standards are
designed for a particular type of measurement and are not necessarily suitable for the evaluation of
vibration exposure. However, in some circumstances, it may be appropriate to ensure that workplace
measurements of vibration are made using locations and axes compatible with those used for emission
measurements.
NOTE The ISO 28927 series of standards defines the preferred measurement location as being as close as
possible to the hand between the thumb and the index finger, where an operator normally holds the machine.
While this measurement position could be suitable for emission testing, it is not invariably suitable for workplace
exposure assessment.
Page 8, 6.1.4.1
Replace the subclause with the following.
6.1.4.1 General
The accelerometers should be rigidly attached to the vibrating surface. Annex D gives details of some
mounting methods. A method shall be chosen which gives an adequate coupling to the vibrating
surface, does not interfere with the operation of the machine, and does not itself affect the vibration
