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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
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.
Attention is drawn to the possibility that some of the elements of this part of ISO 703 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 703-1 was prepared by Technical Committee ISO/TC 41, Pulleys and belts (including
veebelts), Subcommittee SC 3, Conveyor belts.
This first edition of ISO 703-1, together with ISO 703-2, cancel and replace ISO 703:1988, of which they constitute a
technical revision.
ISO 703 consists of the following parts, under the general title Conveyor belts — Transverse flexibility and
troughability:

Introduction
A large number of conveyor belts work in the shape of a trough. If a conveyor belt is too stiff transversely it does not
rest on the central idler roller when unloaded. Its balance is then unstable and it is subject to lateral travel, which
may cause its destruction.
It is possible to make a section of the conveyor belt take on the shape of a trough under its own mass, by
suspending the section by its edges. However, this does not necessarily indicate what happens when the conveyor
belt is not carrying a load.
The results obtained from this method of test will however allow an assessment to be made as to whether the
troughing characteristics of the conveyor belt are suitable for the angle of inclination of the side idler rolls of the
installation on which the belt is to be installed.

Conveyor belts — Transverse flexibility and troughability —
Part 1:
Test method
1 Scope
This part of ISO 703 specifies a method for determining the transverse flexibility (in terms of troughing ability) of
conveyor belts. This method is not suitable or valid for light conveyor belts as described in EN 873.
NOTE The transverse "flexibility" determined by this method is only indirectly associated with the inverse of flexural
modulus as specified in ISO 178, Plastics — Determination of flexural properties. Nor does it take account of the differences in
"flexibility" as exhibited by three-point and four-point bending, which takes into account the flexural strain and the thickness of
the test piece.
