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).
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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 41, Pulleys and belts (including veebelts),
Subcommittee SC 3, Conveyor belts, in collaboration with the European Committee for Standardization
(CEN) Technical Committee CEN/TC 188, Conveyor belts, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This fifth edition cancels and replaces the fourth edition (ISO 283:2015), which has been technically
revised.
The main changes are as follows:
— addition of conditioning period requirement before being sampled in 6.1;
— clarification of sample width measuring point in 6.3;
— addition of cover reduction requirement in the grip areas in 6.3;
— deletion of the humidity requirement in 6.5.
Any feedback or questions on this document should be directed to the user’s national standards body. A

INTERNATIONAL STANDARD ISO 283:2023(E)
Textile conveyor belts — Full thickness tensile strength,
elongation at break and elongation at the reference load —
Test method
1 Scope
This document specifies a test method for the determination of the full thickness tensile strength in
the longitudinal direction and the elongation at the reference force and breaking point of conveyor
belts having a textile carcass. The method can also be used for the determination of full thickness
tensile strength in the transverse direction and the elongation at the breaking point, for use when the
manufacturer is requested by the purchaser to state values for these properties.
This document does not apply to light conveyor belts as described in ISO 21183-1.
