Mechanical vibration and shock - Hand-arm vibration - Measurement and evaluation of the vibration transmissibility of gloves at the palm of the hand (ISO 10819:2013)

This International Standard specifies a method for the laboratory measurement, data analysis, and reporting of the vibration transmissibility of a glove with a vibration-reducing material that covers the palm, fingers, and thumb of the hand. This International Standard specifies vibration transmissibility in terms of vibration transmitted from a handle through a glove to the palm of the hand in one-thirdoctave frequency bands with centre frequencies of 25 Hz to 1 250 Hz. The measurement procedure specified in this International Standard can also be used to measure the vibration transmissibility of a material that is being evaluated for use to cover a handle of a machine or for potential use in a glove. However, results from this test cannot be used to certify that a material used to cover a handle meets the requirements of this International Standard to be classified as an antivibration covering. A material tested in this manner could later be placed in a glove. When this is the case, the glove needs to be tested in accordance with the measurement procedure of this International Standard and needs to meet the vibration attenuation performance requirements of this International Standard in order to be classified as an antivibration glove.

Vibrations et chocs mécaniques - Vibrations main-bras - Mesurage et évaluation du facteur de transmission des vibrations par les gants à la paume de la main (ISO 10819:2013)

L'ISO 10819:2013 spécifie une méthode de mesurage en laboratoire, d'analyse des données et d'enregistrement du facteur de transmission des vibrations d'un gant fabriqué à l'aide d'un matériau antivibratile qui recouvre la main et les doigts, dont le pouce. L'ISO 10819:2013 spécifie le facteur de transmission des vibrations en termes de transmission des vibrations d'une poignée à la paume de la main à travers un gant dans les bandes de fréquences de tiers d'octave avec des fréquences centrales allant de 25 Hz à 1 250 Hz.
Le mode opératoire de mesurage spécifié dans l'ISO 10819:2013 peut aussi être utilisé pour mesurer le facteur de transmission des vibrations d'un matériau devant être évalué afin d'être utilisé pour recouvrir la poignée d'une machine ou dans la fabrication d'un gant. Toutefois, les résultats de cet essai ne peuvent pas être utilisés afin de certifier qu'un matériau utilisé pour couvrir une poignée est conforme aux exigences de l'ISO 10819:2013 et ainsi être classé comme étant un matériau antivibratile. Un matériau soumis à essai de cette façon pourrait être placé dans un gant. Lorsque c'est le cas, il est nécessaire de soumettre à essai le gant conformément au mode opératoire de mesurage de l'ISO 10819:2013; le gant doit satisfaire aux exigences de performance d'atténuation des vibrations de l'ISO 10819:2013 afin d'être classé comme étant un gant antivibratile.

Mehanske vibracije in udarci - Vibracije dlan-roka - Merjenje in vrednotenje prenosov vibracij z rokavice na dlan roke (ISO 10819:2013)

Ta mednarodni standard določa metodo za opravljanje laboratorijske meritve, izvedbo analize podatkov in poročanje o prenosljivosti vibracij za rokavico z materialom, ki zmanjšuje vibracije ter pokriva dlan in prste roke. V tem mednarodnem standardu je prenosljivost vibracij določena kot stopnja vibracij, ki se z ročice prenašajo skozi rokavico na dlan roke v terčnih frekvenčnih pasovih s srednjimi frekvencami 25–1250 Hz. Merilni postopek, določen v tem mednarodnem standardu, se lahko uporabi tudi za merjenje prenosljivosti vibracij materiala, ki je v postopku vrednotenja ustreznosti za prekritje ročice stroja ali morebitno uporabo v rokavici. Vendar rezultati tega preskusa se ne morejo uporabiti za overjanje materiala, ki prekriva ročico, v povezavi z zahtevami tega mednarodnega standarda glede njegove ustreznosti za uporabo kot protivibracijske zaščitne obloge. Material, preskušen na ta način, se lahko naknadno uporabi v rokavici. V tem primeru je treba rokavico preskusiti v skladu z merilnim postopkom v tem mednarodnem standardu, rokavica pa mora izpolnjevati zahteve glede zmanjšanja vibracij v tem mednarodnem standardu, da se lahko overi kot protivibracijska rokavica.

ISO 10819:2013(E)
Introduction

Because of the growing demand to reduce health risks associated with exposure to hand-transmitted

vibration, gloves with vibration-reducing materials are often used to attenuate vibration transmitted to

the hands. These gloves normally provide little reduction in hand-transmitted vibration at frequencies

below 150 Hz. Some gloves can increase the vibration transmitted to the hands at these low frequencies.

Gloves with vibration-reducing materials that meet the requirements of this International Standard to be

classified as an antivibration glove can be expected to reduce hand-transmitted vibration at frequencies

above 150 Hz. These gloves can reduce but not eliminate health risks associated with hand-transmitted

vibration exposure.

Field observations indicate that gloves with vibration-reducing materials can result in positive and

negative health effects. Positive health effects can occur with gloves that reduce finger tingling and

numbness and that keep the hands warm and dry. Negative health effects can occur with gloves that

increase the vibration transmitted to the hands at low frequencies and that increase hand and arm

fatigue because they increase the hand grip effort required to control a vibrating machine.

Gloves tested in accordance with the requirements of this International Standard are evaluated in a

controlled laboratory environment. The actual vibration attenuation of a glove in a work environment

can differ from that measured in a controlled laboratory environment.

Vibration transmissibility measurements made in accordance with the requirements of this International

Standard are performed only at the palm of the hand. The transmission of vibration to the fingers is not

measured. When evaluating the effectiveness of a glove with a vibration-reducing material used to reduce

vibration transmitted to the hand, vibration transmission to the fingers should also be assessed. However,

research subsequent to the publication of this International Standard is needed to develop a measurement

procedure that can be used to measure the vibration transmissibility of gloves at the fingers.

The measurement procedure specified in this International Standard only addresses glove properties

that can reduce health risks associated with hand-transmitted vibration in work environments. It does

not address glove properties necessary to reduce other hand-related health and safety risks in work

environments.

The measurement procedure specified in this International Standard can also be used to measure the

vibration transmissibility of a material that is being evaluated for use to cover a handle of a machine or

for potential use in a glove.

INTERNATIONAL STANDARD ISO 10819:2013(E)
Mechanical vibration and shock — Hand-arm vibration
— Measurement and evaluation of the vibration
transmissibility of gloves at the palm of the hand

WARNING — This International Standard defines a screening test procedure for measuring the

vibration transmission through gloves with an embedded vibration-reducing material. Many factors

not addressed in this International Standard can influence the transmission of vibration through

these gloves. Therefore, use the vibration transmissibility values obtained in accordance with this

International Standard with caution in the assessment of the vibration-reducing effects of gloves.

1 Scope

This International Standard specifies a method for the laboratory measurement, data analysis, and

reporting of the vibration transmissibility of a glove with a vibration-reducing material that covers the

palm, fingers, and thumb of the hand. This International Standard specifies vibration transmissibility

in terms of vibration transmitted from a handle through a glove to the palm of the hand in one-third-

octave frequency bands with centre frequencies of 25 Hz to 1 250 Hz.

The measurement procedure specified in this International Standard can also be used to measure the

vibration transmissibility of a material that is being evaluated for use to cover a handle of a machine

or for potential use in a glove. However, results from this test cannot be used to certify that a material

used to cover a handle meets the requirements of this International Standard to be classified as an

antivibration covering. A material tested in this manner could later be placed in a glove. When this is the

case, the glove needs to be tested in accordance with the measurement procedure of this International

Standard and needs to meet the vibration attenuation performance requirements of this International

Standard in order to be classified as an antivibration glove.

5 Measuring principle and equipment
5.1 General principle and setup

The method specified in this International Standard is used to measure the vibration input to a gloved

hand that is transmitted through the glove at the palm of the hand, which grips and pushes on an

instrumented handle. The glove vibration transmissibility (3.1) measured at the palm is used as an

index to judge the vibration-reducing effectiveness of the glove. A vibration excitation system (normally

an electromechanical shaker) shall be used to generate the required vibration input. The vibration in

the direction of the excitation shall be simultaneously measured at the middle point of the top of the

instrumented handle (see Annex A) and between the palm of the hand and glove by means of a palm

adaptor. The adaptor shall contain an accelerometer and shall be placed inside the glove between the

hand and handle. To compensate for the frequency response of the palm adaptor, the glove vibration

transmissibility is calculated as the ratio of the vibration transmissibility values at the palm of the hand

with a glove, as measured with the palm adaptor, divided by the corresponding transmissibility values

associated with the bare palm adaptor attached to the handle.

A schematic drawing of a recommended vibration measurement setup is shown in Figure 1. The

acceleration at the reference point in the instrumented handle, a ( f ), and the vibration at the palm

R i

of the hand, a ( f ) or a ( f ), shall be measured simultaneously. Annex A shows examples of

h(Pb) i h(Pg) i

instrumented handles. The diameter of that part of the instrumented handle that is clasped by the hand

shall be (40 ± 0,5) mm.

The values of the grip and feed forces shall be displayed continuously so the test subject can continually

monitor them and consistently apply the required grip and feed forces throughout a test.
