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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO9856 was prepared by Technical Committee ISO/TC41, Pulleys and belts (including veebelts),
Subcommittee SC 3, Conveyor belts.
This second edition cancels and replaces the first edition (ISO 9856:1989), which has been technically revised.

Introduction
This International Standard is used in a number of situations where the permanent elongation of the conveyor
belt after mechanical conditioning is of some practical relevance and in particular in the implementation of
ISO 3870 and the application of ISO 5293.
The equation for the calculation of the elastic modulus in the 1989 edition contained an error and omitted to
calculate the permanent elongation of the conveyor belt. In addition the figure illustrating the hysteresis loop of
the conveyor belt during mechanical conditioning was misleading and ambiguous.
These omissions and anomalies have been corrected in the present edition.
