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.
ISO 4167 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 248, Textiles and textile products, in collaboration with Technical Committee ISO/TC 38, Textiles, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 4167:1979), of which it constitutes a technical
revision.

on similar machines
3.2
batch
definite quantity of twine produced under conditions which are presumed uniform
3.3
laboratory sample
total selection of samples from a batch intended for testing in the laboratory

4 Designation
A twine shall be designated by
⎯ the words “agricultural twine”,
⎯ the number of this International Standard, i.e. ISO 4167,
⎯ the material from which the agricultural twine is made, and
⎯ the nominal runnage in metres (m) per kilogram (kg) of the agricultural twine.
EXAMPLE Designation example:
A polypropylene (PP) agricultural twine having a nominal runnage of 350 m/kg is designated as follows:
agricultural twine ISO 4167 - PP - 350
5 Raw materials
The raw material used for the manufacture of twine shall consist of polyolefin. Adequate stabilization against
degradation by sunlight shall be incorporated.
Any ultraviolet (UV) inhibitor system as well as colour pigment may be used.
Used colour pigment and stabilizers should not be toxic.
NOTE Attention is drawn to the fact that in some areas of the world, a more stringent level of stabilization may be
necessary than in others.
The colour of the twine shall be distinguishable from straw and grass.
6 Manufacture
Each spool of twine shall be capable of working with continuity throughout its length. The twine shall have a Z
twist in accordance with ISO 2.
Twine should always be removed from the centre of a spool in an anti-clockwise direction.
7 Technical properties
The methods used for measuring the technical properties of the agricultural twine shall be as given in Table 1.
Table 2 shows indicative characteristics of some twines only; others shall be calculated in accordance with the
formulae in this clause and in 9.1.5.
In order to assure a minimum quality level, the following formulae are given for determining the technical
characteristics of the agricultural twines.
