European foreword
This document (EN 15194:2017/prA2:2022) has been prepared by Technical Committee CEN/TC 333
“Cycles”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
In comparison with the previous edition, the following technical modifications have been made:
— Clause 5 “Marking, labelling”: the reference to CE marking is removed;
— Addition of Annex K to give a method aiming at measuring the vibrations to which a cyclist is
subjected.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
EU Directive(s) / Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, which is an integral part
of this document.

(informative)
Vibration measurements on EPACs
K.1 General
In order to comply with the requirements of Directive 2006/42/EC (Machinery Directive), information
is to be provided on the vibrations that can occur in machines where the operator may be exposed to
vibrations due to the operation of the machine itself or due to the movement of the machine on uneven
ground. The test method described below is limited to cycles for professional use.
For EPACs, vibration excitations result without exception from riding; therefore, the test of whole-body
vibrations and hand-arm vibrations is based on the driving mode and thus complies with EN 1032.
An uncertainty is specified for the validity of the measurements, which is 0,4 times the vibration values
specified in EN 12096. Further investigations should be carried out to reduce this uncertainty range as
soon as vibration data obtained from different measuring facilities are available.
K.2 Basic standards
European Standards EN 1032 and EN 12096 are the basic standards relevant to the formulation of a
vibration measurement standard for mobile machinery.
EN 1032 describes the determination of whole-body and hand-arm vibrations of the operator during the
testing of mobile machinery; EN 12096 provides guidance on how to declare vibration emission values
of machinery and specifies requirements for the verification of specified values.
K.3 Values to be measured
The following values are to be measured or determined:
— a : root mean square (r.m.s.) value of the frequency-weighted acceleration of the vertical whole-
wz
body vibration according to EN 1032, measured on the saddle of the EPAC.
— a : mean value of N r.m.s. values of the weighted vertical whole-body vibration of a valid test series.
wzS
— a , a , a : r.m.s. values of the frequency-weighted acceleration of the hand-arm vibration in the
hwx hwy hwz
x, y and z directions according to EN ISO 5349-1, measured on the handlebar grip of the EPAC.
: total vibration value of the r.m.s. values of the frequency-weighted acceleration of the hand-arm
— ahv
vibrations according to EN ISO 5349-1. This results from the measurements of the r.m.s. values of the
frequency-weighted acceleration in the x, y and z directions according to:

(K.1)
— a : mean value of N r.m.s. values of the total vibration value of the frequency-weighted acceleration
hvH
of the hand-arm vibrations of a valid test series.
— Mean speed of the EPAC when moving along the test track. This velocity can be determined from the
time spent running along the test track or by using the measuring equipment specified in K.3.5.
— The tire pressure shall be checked immediately before the measurement.
— Ambient air temperature.
K.3 Instrumentation
K.3.1 General
Accelerometers shall be used for the measurement of vibrations. Accelerometers shall be attached in
accordance with ISO 5348 and in accordance with the instructions of the accelerometer manufacturer.
K.3.2 Vibration transducers for whole-body vibrations
The general requirements for mounting the vibration transducer are given in EN 1032:2003+A1:2008,
7.2. For measurement on the saddle, the use of a vibration transducer in a semi-elastic seat pad is not
practical; therefore, the vibration transducer shall be placed directly on the saddle surface in such a way
that the transducer is located centrally between the ischial tuberosities of the seated person (see Figure
K.1). For reasons of comfort or due to the design of the saddle, it is permissible to position the transducer
slightly (up to 50 mm) in front of or behind the ischial tuberosities. A transducer that is as flat as possible
should be used; preferably, the transducer should be adhered to the saddle surface, e.g. with double-sided
adhesive tape.
The measurement shall be taken in the vertical (z) direction.

K.3.3 Vibration transducers for hand-arm vibrations
General requirements for the measurement and evaluation of human exposure to hand-transmitted
vibration can be found in EN ISO 5349-1, and guidance on the mounting of vibration transducers is given
in EN ISO 5349-2:2001 , Annex D.
For measurements on the handlebar grip of the EPAC, it is possible to mount the vibration transducer
both on the handlebar tube and on the handlebar grip, with the transducer preferably positioned as close
as possible to the hand between the thumb and index finger, as given in EN ISO 20643:2008 , 6.1,
Figure 1 a) (see Figure K.2).
The vibration transducer shall not interfere with the operator's usual method of holding the handlebar,
as this would influence the vibration behaviour at the handlebar and thus the measurement results.
The measurements shall be carried out in all three measuring directions. It is sufficient to record the
hand-arm vibration with one sensor (on the right or left of the handlebar grip).

K.3.4 Frequency weighting and integration time
The frequency weighting and the characteristic values of the bandpass filters shall comply with
EN 1032:2003+A1:2008, 7.3.
For each test, the r.m.s. value of acceleration shall be the linearly integrated average (interval r.m.s. value)
for a complete test run on the test track (see K.4.2).
Preferably, the recording of all measured values (whole-body vibrations in vertical (z-) direction and
hand-arm vibrations by means of a multi-axis transducer in x-, y- and z-direction) should be made
simultaneously on the test track.
