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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
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 .
This third edition cancels and replaces the second edition (ISO14890:2013), which has been technically
revised and minor editorial revised.
The main changes are as follows:
— Remove code letter G and its correspondent yarn of Glass from Table 1;
— Revise longitudinal joints numbers of Table 7;
— Include more tensile strength categories into Table 8 ;

Conveyor belts — Specification for rubber- or plastics-
covered conveyor belts of textile construction for general use
1 Scope
This document specifies requirements for rubber and/or plastics covered conveyor belting of textile
construction for general surface use on flat or troughed idlers.
This document is not suitable or valid for light conveyor belts as described in ISO 21183-1.
Items that are not requirements of this document, but need to be agreed between the manufacturer and the
purchaser, are included in Annex A.
A list of the details intended to be supplied by the purchaser of belting with an enquiry is given in Annex B.

3.1
tensile strength
greatest measured force during the tensile test divided by the width of the test piece
Note 1 to entry: It is expressed in newton per milimetre (N/mm).
3.2
reference force
10 % of the nominal tensile strength in the longitudinal direction multiplied by the width of the test piece in
millimetres
Note 1 to entry: It is expressed in Newton.
EXAMPLE
Nominal tensile strength = 1 600 N/mm;
reference force = 160 N/mm;
reference force for 25 mm test piece = 25 mm × 160 N/mm = 4 000 N.
3.3
slab belt
conveyor belt made in wide widths and long lengths for subsequent slitting and cutting into narrower widths
and shorter lengths to suit individual conveyor installations
3.4
solid woven belt
conveyor belt consisting of a carcass of more than one ply, the plies being interlocked in the weave or bound
together by binding threads in the course of weaving
3.5
mono-ply belt
conveyor belt with a carcass consisting of one ply of woven textile fabric
3.6
duo-ply belt
conveyor belt with a carcass consisting of two plies of woven textile fabric, bonded together by an intermediate
layer of elastomer of sufficient thickness to allow the incorporation of a tension element in the joint
3.7
multi-ply belt
conveyor belt with a carcass of two or more plies of woven textile fabric, the adjacent plies being bonded
together by an intermediate layer of elastomer
3.8
primary yarn
load carrying yarn that contributes more than 50 %of the tensile strength
3.9
secondary yarn
load carrying yarn that contributes less than 50 %of the tensile strength
