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.

conveyor belts of textile construction for general use
1 Scope
This International Standard specifies requirements for rubber and/or plastics covered conveyor belting of textile
construction for general surface use on flat or troughed idlers.
This International Standard is not suitable or valid for light conveyor belts as described in ISO 21183-1.
Items that are not requirements of this International Standard, 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.

The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced document
(including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
tensile strength
greatest measured force during the tensile test divided by the width of the test piece
NOTE It is expressed in newton per millimetre (N/mm).
© ISO 2013 – All rights reserved 1
---------------------- Page: 13 ----------------------
SIST EN ISO 14890:2013
ISO 14890:2013(E)
3.2
reference force
reference load
one tenth of the nominal tensile strength in the longitudinal direction multiplied by the width of the test piece
in millimetres
NOTE It is expressed in Newton.
EXAMPLE
Nominal tensile strength = 1 600 N/mm;
reference force = 160N/mm;
reference force for 25 mm test piece = 25mm × 160 N/mm = 4 000 N.
3.3
slab belting
conveyor belting 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 belting
conveyor belting 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 belting
conveyor belting with a carcass consisting of one ply of woven textile fabric
3.6
duo-ply belting
conveyor belting 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 belting
conveyor belting 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
4 Designation
4.1 Belting designation
Belting is designated by reference to the following conveyor belt characteristics:
a) a reference to this International Standard, i.e. ISO 14890;
b) the required length, in metres;
c) the required width, in millimetres (see Table 4);
d) the fibre type of the carcass, in both the warp and weft directions, e.g. polyester (E) (warp) and polyamide
(P) (weft) (EP) (see Table 1);

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 14890:2012(E)
Conveyor belts — Specification for rubber- or plastics-covered
conveyor belts of textile construction for general use
1 Scope
This International Standard specifies requirements for rubber and/or plastics covered conveyor belting of textile
construction for general surface use on flat or troughed idlers.
This International Standard is not suitable or valid for light conveyor belts as described in ISO 211831.
Items that are not requirements of this International Standard, 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 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
tensile strength
greatest measured force during the tensile test divided by the width of the test piece
NOTE It is expressed in newton per millimetre (N/mm).

3.2
reference force
reference load
one tenth of the nominal tensile strength in the longitudinal direction multiplied by the width of the test piece
in millimetres
NOTE It is expressed in Newton.
EXAMPLE
Nominal tensile strength = 1 600 N/mm;
reference force = 160N/mm;
reference force for 25 mm test piece = 25mm × 160 N/mm = 4 000 N.
3.3
slab belting
conveyor belting 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 belting
conveyor belting 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 belting
conveyor belting with a carcass consisting of one ply of woven textile fabric
3.6
duo-ply belting
conveyor belting 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 belting
conveyor belting 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
4 Designation
4.1 Belting designation
Belting is designated by reference to the following conveyor belt characteristics:
a) a reference to this International Standard, i.e. ISO 14890;
b) the required length, in metres;
c) the required width, in
