La présente norme internationale prescrit une méthode de mesurage en laboratoire, d'analyse des données et d'enregistrement du facteur de transmission des vibrations par les gants en termes de transmission des vibrations d'une poignée à la paume de la main, dans la gamme de fréquences comprise entre 31,5 Hz et 1 250 Hz. La présente norme est destinée à définir un essai de sélection pour la transmission des vibrations par les gants. Il est reconnu que de nombreux facteurs influencent la transmission des vibrations par les gants. La valeur du facteur de transmission obtenu selon la présente norme ne suffit donc pas pour évaluer le risque sanitaire dû aux vibrations. Le facteur de transmission des vibrations est mesuré et noté pour deux spectres d'entrée qui sont représentatifs pour les vibrations de certains outils, et peut être noté en fonction de la fréquence.

Foreword
ISO (the International Organization for Standardization) is a worldwide fed-
eration of national Standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
technical committees. Esch member body interested in a subject for
which a technical committee has been established has the right to be rep-
resented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO col-
laborates closely with the International Electrotechnical Commission (IEC)
on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are cir-
culated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 10819 was prepared by the European Commit-
tee for Standardization (CEN) in collaboration with ISO Technical Commit-
tee TC 108, Mechanical Vibration and shock Subcommittee SC 4, Human
exposure to mechanical Vibration and shock in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).

Foreword
The text of EN ISO 10819:1996 has been prepared by Technical Committee CEN/TC 162
‘Protective clothing including hand and arm protection and lifejackets ”,the secretariat of which is
held by DIN, in collaboration with Technical Committees ISO/TC 108 ‘Mechanical Vibration and
shock ”and CEN/TC 231 ‘Mechanical Vibration and shock ”.
This European Standard shall be given the Status of a national Standard, either by publication of
an identicai text or by endorsement, at the latest by December 1996, and conflicting national
Standards shall be withdrawn at the latest by December 1996.
This European Standard has been prepared under a mandate given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Directiveis).
There are five annexes to this Standard whereof annex A is normative and annexes B, C, D and
ZA are for information only.
According to the CEN/CENELEC Internal Regulations, the national Standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Denmark,
Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway,
Portugal, Spain, Sweden, Switzerland and the United Kingdom.
lntroduction
This European Standard was developed in response to the growing demand to protect People
from the risks of Vibration darnage caused by exposure to hand-transmitted Vibration.
In the field of personal protective equipment (PPE), gloves arc being marketed which arc
intended to reduce the magnitude of Vibration exposure.
On present evidente, there have been no circumstances in which gloves have been shown to
prov;de adequate attenuation of Vibration to prevent Vibration injuries.
Within the current state of knowledge, gloves do not provide significant attenuation in the
frequency range below 150 Hz. Some gloves may provide amplification in this frequency range.
Also, the use of gloves might alter the gripping forte which would alter the transmission of
Vibration into the arms thus increasing the risk of darnage. However, it must be emphasized that
an important purpose of gloves is to keep the hands warm and dry, as this may help to limit
some Vibration-induced effects.
This Standard describes a method of measuring the Vibration transmissibility of gloves in the
laboratory, but as far as possible under conditions typical of use at actual working places. The
measurement is performed at the palm of the hand and so does not give the transmission of
Vibration to the fingers. However, when evaluating the protective effects of a glove, it must be
remembered that in many work situations Vibration is transmitted not only to the palm hutalso
to the fingers. A different measurement procedure will be required to establish the Vibration
transmissibility of gloves at the fingers.
This Standard describes a method of measuring the Vibration transmissibility of gloves worn by
a test subject. For the measurement of the Vibration transmissibility of resilient materials which
are used to cover handles of tools or make gloves, EN ISO 13753 should be consulted=

1 scope
This European Standard specifies a method for the laboratory measurement, the data analysis
and reporting of the Vibration transmissibility of gloves in terms of Vibration transmission from a
handle to the palm of the hand in the frequency range from 31,5 Hz to 1250 Hz.
The Standard is intended to define a screening test for the Vibration transmission through
glovas. It is recognised that many factors influence the transmission of Vibration through gloves.
Therefore the transmissibility value according to this Standard is not sufficient to assess the
health risk due to Vibration.

3 Definitions
The terminology used in this Standard is in accordance with ISO 2041, ISO 5805 and
ENV 25349. Additionally for the purposes of this Standard, the following definition applies:
Transmissibility: the ratio of the accelerations measured at the surface of the hand and at the
reference Point. Transmissibility values greater than 1 indicate that the glove amplifies the
Vibration. Values lower than 1 indicate that the glove attenuates the Vibration.

5 Measuring principle and equipment
5.1 General principle and setup
The method uses a Vibration excitation System (“shaker ”) equipped with a special handle (see
annex B) to measure the gripping forte and a device for measuring the feed forte. The Vibration
in the direction of the excitation is measured at two Points simultaneously: at the surface of the
by means of an adaptor containing an accelerometer - between hand and glove,
handle and -
i. e. inside the glove. In Order to compensate for the frequency response of the adaptor, the
Vibration transmissibility of the glove is calculated as the differente in Vibration transmissibility
from handle to hand with and without glove.
at the
The measuring setup is shown in figure 1. The acceleration at the reference Point (
handle) and the Vibration at the hand shall be measured simultaneously.
