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 on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that

Introduction
The coefficient of friction of light conveyor belts has to be seen from two different aspects relevant to the
choice of the reference material. One aspect is the friction of the underside of the belt. In practice, this is not
critical because it is low. Regardless of whether a table of steel or of wood is used, the coefficient of friction is
within the range from 0,2 to 0,3 in most cases.
Contrary to this, the top face covers show values over an extended range dependent on their actual function.
To achieve this function, the material itself can be modified as well as the surface pattern but the test
procedure is the same in every case. So it becomes clear that the chosen steel panel represents a compromise.
Its main properties are reproducibility of the surface finish and uncritical friction behaviour against any
kind of belt cover.
This International Standard allows comparison of all kinds of conveyor belt to obtain reliable results as a
reference. This can be helpful to buyers who need guidance in choosing the right belt for their particular
application.
The tests in accordance with this International Standard are limited to dynamic coefficients of friction
(μ ) up to 1,0 and static coefficients of friction (μ ) up to 1,5. Higher values can show a mixture of friction,
D S
adhesion, deformation and other effects occurring, especially where the surface texture is coarse and is
therefore unsuitable for this test.
The method using the standardized metallic test panel is intended especially to compare the coefficients of
friction of different light conveyor belts. The values received under practice conditions always depend on
the frictional partners.
To determine these effects, it is possible to choose a different frictional partner instead of the panel if
required. This is mentioned in the test report.
