Conveyor belts - Transverse flexibility (troughability) - Test method (ISO 703:2017)
This document specifies a test method for determining the transverse flexibility (troughability) of a
conveyor belt, expressed as a ratio, F/L. The method is not suitable or valid for light conveyor belts as
described in ISO 21183-1.
NOTE The transverse “flexibility” determined by the method described in this document is only indirectly
associated with the inverse of flexural modulus as specified in ISO 178. Nor does it take into consideration the
differences in “flexibility” as exhibited by three-point and four-point bending, which takes account of the flexural
strain and the thickness of the test piece.

Courroies transporteuses - Flexibilité transversale (aptitude à la mise en auge) - Méthode d'essai (ISO 703:2017)
ISO 703:2017 spécifie une méthode d'essai pour déterminer la flexibilité transversale (aptitude à la mise en auge) d'une courroie transporteuse, exprimée comme le rapport F/L. Cette méthode n'est pas applicable ou valable pour les courroies transporteuses légères décrites dans l'ISO 21183‑1.
Naprave za kontinuirni transport - Trakovi tračnih transporterjev - Prečna upogibnost - Preskusna metoda (ISO 703:2017)
Ta dokument določa preskusno metodo za ugotavljanje prečne upogibnosti
trakov tračnih transporterjev, izraženo kot razmerje F/L. Ta metoda ni primerna oziroma veljavna za lahke trakove tračnih transporterjev, kot so opisani v standardu ISO 21183-1.
OPOMBA: Prečna »upogibnost«, določena z metodo, opisano v tem dokumentu, je le posredno povezana z nasprotno vrednostjo upogibnega modula, kot je določen v standardu ISO 178. Prav tako ne upošteva razlik v »upogibnosti«, značilne za tri- in štiritočkovno upogibanje, ki upošteva upogibno deformacijo in debelino preskušanca.

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 nongovernmental, 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
