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, 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, 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 ).

Introduction

The indentation rolling resistance is caused by the energy loss connected to the deformation of the conveyor belt due to its contact with the idler. Apart from the technological properties of the conveyor belt, the magnitude of the indentation rolling resistance depends on the following factors:

• design of the conveyor belt, especially the pulley side cover plate thickness;
• vertical load;
• idler diameter;
• ambient temperature;
• belt speed.

The width-related indentation rolling resistance is measured in a test rig with an idler which exerts an evenly distributed vertical force on the belt. An indentation rolling resistance to be used for the design of belt conveyors for an idler station with more than one idler can only be calculated considering the vertical forces and their distribution between belt and idler (refer to Annex A).

1 Scope

This document defines a method for the determination of the width-related indentation rolling resistance of conveyor belts. The goal is to be a full-scale test and simulation on finished belt constructions which are reproducible and relevant for the practical use. The test results can be used for a comparison of conveyor belts and for design of belt conveyors with steel cord and fabric conveyor belts.

This document is not suitable or valid for light conveyor belts described in ISO 21183-1.
