Mechanical vibration - Guideline for the assessment of exposure to hand-transmitted vibration using available information including that provided by manufacturers of machinery
This document gives guidelines for estimating and documenting the daily vibration exposure due to the use of hand-held power tools and hand-guided machines, in relation to the requirements of the European Physical Agents Directive (vibration) 2002/44/EC. This document is addressed to competent services for the assessment of vibration exposure at the workplace and to national authorities and industrial organizations.
The methods in this document are based on the requirements and guidance given in EN ISO 5349 1 and EN ISO 5349 2 but instead of measuring the vibration magnitudes at the specific workplaces, the methods in this document use existing vibration values from other sources of information including those provided by the manufacturers of the machinery in relation to the requirements of the Machinery Directive 2006/42/EC.
This document gives guidance on how to estimate the exposure time and the daily vibration exposure A(8) as defined in EN ISO 5349 1. It also offers a simple method for estimating the daily vibration exposure by means of a table which indicates the vibration exposure as a function of the equivalent vibration total value and the associated exposure time. Both methods can be used even in cases of multiple exposures on the same day.

This document (CEN/TR 15350:2020) has been prepared by Technical Committee CEN/TC 231
“Mechanical vibration and shock”, the secretariat of which is held by DIN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TR 15350:2013.
The main changes are as follows:
— Document brought in line with CEN/TR 1030-2:2016 by removing content already covered there;
— Annex B updated by explaining the procedure for identifying vibration risks that need to be
controlled;
— Annex C now based on harmonized standards published after 2007 (e.g. EN 60745, EN 62841,
EN ISO 28927, EN ISO 22867), providing more realistic results, without the need of multiplying
factors, formely used for correcting the risk of underevaluating vibration exposure;
— new Annex D included, providing the estimation of exposure duration with examples of indicative
exposure durations according to the quality of operators.
Introduction
This document provides information on how to estimate the exposure time (exposure duration) and
how to assess the vibration exposure from hand-held power tools and hand-guided machines. The
methods described use existing vibration emission values declared for the machine of interest or
information coming from other sources.
Daily vibration exposure depends on both the average vibration magnitude at the vibrating surface in
contact with the hand and the total user time for which an employee is in contact with that vibration.
EN ISO 5349-1 notes that vibration is affected by many factors, such as force, posture, inserted tools etc.
It is therefore important to recognize that vibration exposure values are estimates of true exposures
and therefore estimates of true risk from hand-arm vibration. To make good exposure assessments it is
important to have an appreciation of the limitations of different vibration information sources (sources
such as collated information on types of machine, manufacturer’s declared emission values, or
workplace). However, it is also important to recognize when your estimate of exposure is sufficiently
precise for your application.
It is important that the vibration values used in the exposure assessment are representative of those in
the specific use of the machinery. Workplace measurements, however, are required if suitable data are
not available to represent the vibration under the specific working conditions or if the calculation
results do not help to decide whether or not the vibration exposure limit value or exposure action value
is likely to be exceeded or if appropriate information from health surveillance shows needs of
precaution.
1 Scope
This document gives guidelines for estimating and documenting the daily vibration exposure due to the
use of hand-held power tools and hand-guided machines, in relation to the requirements of the
European Physical Agents Directive (vibration) 2002/44/EC. This document is addressed to competent
services for the assessment of vibration exposure at the workplace and to national authorities and
industrial organizations.
The methods in this document are based on the requirements and guidance given in EN ISO 5349-1 and
EN ISO 5349-2 but instead of measuring the vibration magnitudes at the specific workplaces, the
methods in this document use existing vibration values from other sources of information including
those provided by the manufacturers of the machinery in relation to the requirements of the Machinery
Directive 2006/42/EC.
This document gives guidance on how to estimate the exposure time and the daily vibration exposure
A(8) as defined in EN ISO 5349-1. It also offers a simple method for estimating the daily vibration
exposure by means of a table which indicates the vibration exposure as a function of the equivalent
vibration total value and the associated exposure time. Both methods can be used even in cases of
multiple exposures on the same day.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 5349-2 and the following
apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at http://www.electropedia.org/
3.1
user time
user time of the work involving the use of the machinery, i.e. including the interruptions required by the
work and the break periods directly related to the use
Note 1 to entry: This is more likely to be reported by the operator than the exposure time (see 3.2).
3.2
exposure time
T
total duration the hand is in direct contact with the vibrating surface (handle, work piece, etc.)
EXAMPLE The user time for mounting wheels on five automobiles is estimated by the operator at 1 h per
day; but the exposure time is just 5 cars x 4 lug nuts x 4 wheels x 2 loosening/tightening actions x 4 s which yields
T = 0,18 h. The exposure proportion is only 18 %.
Note 1 to entry: The exposure time is often confused with the user time when estimating the daily exposure
time T.
