Mechanical vibration and shock - Hand-arm vibration - Method for measuring the vibration transmissibility of resilient materials when loaded by the hand-arm system (ISO 13753:1998)

This International Standard specifies a procedure to determine the vibration transmissibility of a resilient material when loaded by the hand-arm system. The method is applicable to all materials which behave in a linear way. It is expected that this is realized in most elastic foam and rubber materials and, provisionally, in woven cloths. The method can be applied to mixed systems, e.g. a cloth material attached to a foam or rubber base. It is expected that the results of this laboratory test will be used in screening materials used for vibration attenuation on the handles of tools and for gloves. This will enable rank ordering of materials for gloves, but will not necessarily predict the transmissibility of the gloves fabricated from these materials (for this purpose, see ISO 10819).

Mechanische Schwingungen und Stöße - Hand-Arm-Schwingungen - Verfahren zur Messung der Schwingungsübertragung elastischer Materialien unter Belastung durch das Hand-Arm-System (ISO 13753:1998)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Schwingungsübertragung eines elastischen Materials fest, wenn dieses mit dem Hand-Arm-System belastet wird.
Das Verfahren ist für alle Materialien gültig, die lineares Verhalten aufweisen. Erfahrungsgemäß trifft das bei den meisten geschäumten Materialien und bei Gummi zu und mit Einschränkung auch bei gewebtem Stoff. Das Verfahren gilt auch für Verbundmaterialien, wie z. B. Stoff auf einer geschäumten oder einer Gummi-Unterlage.
Die nach diesem Labormessverfahren ermittelten Werte sollen zur Kennzeichnung von Materialien dienen, die zur Schwingungsminderung an Handgriffen von Maschinen und zur Herstellung von Handschuhen verwendet werden. Somit ist eine hierarchische Klassifizierung solcher Handschuh¬materialien möglich, ohne dass aber notwendigerweise die Übertragungseigenschaft der aus diesen Materialien gefertigten Handschuhe vorher¬gesagt wird (zu diesem Zweck siehe ISO 10819).

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

collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.

Introduction
This International Standard was developed in response to the growing
demand to protect people from the risks of vibration damage caused by
exposure to hand-transmitted vibration.
Various standards refer to measurement and assessment of risk to
vibration exposure and to methods of type testing specific tools and
processes.
Resilient materials are used to cover handles and make gloves. It is hoped
that both of these will reduce the magnitude of the vibration exposure. This
International Standard describes a method of measuring the vibration
attenuation of a sample of the material in the form of a flat sheet or layer.
In some cases the material may be of two or more layers forming a sheet.
It is a laboratory measurement and offers a reproducible and reliable
procedure.
This International Standard assumes that the material behaves in a linear
way and that it has negligible mass compared with the mass loading. (A
correction could be made for the material mass if required.) The method
determines the impedance of the material when loaded by a mass
providing a compression force equivalent to that found when the material is
gripped by the hand. This is done by measuring the transfer function of the
mass-loaded material at all the required frequencies. The vibration
transmission when loaded by the hand is computed using standard values
of hand-arm impedance and the measured values of the material
impedance. The impedances used in this International Standard are for the
palm of the hand when gripping a circular handle. The resulting
transmissibility may not be applicable to the fingers. The impedance for the
z direction of the hand-arm system where the material is under
h
compression is used. The mathematical basis of the method is contained in
annex B.
If the results of this measurement procedure show transmissibilities greater
than 0,6 at all frequencies up to 500 Hz, then the material would probably
not provide greater attenuation in the practical situation in the same
frequency range. In the practical situation, the transmissibility as a function
of frequency should be appropriate to the frequency spectrum of the
source.
