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 1889 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and
reinforcement fibres.
This fourth edition cancels and replaces the third edition (ISO 1889:1997), of which it constitutes a minor
revision. The main changes are as follows:
⎯ the scope has been broadened to include all reinforcement-fibre yarns;
⎯ the normative references have been updated;
⎯ the reference to ISO 1886 which was in the first footnote on page 3 has been removed (ISO 1886 has
been withdrawn without replacement).

INTERNATIONAL STANDARD ISO 1889:2009(E)

Reinforcement yarns — Determination of linear density
1 Scope
This International Standard specifies a method for the determination of the linear density of glass-fibre,
carbon-fibre, aramid-fibre and any other reinforcement-fibre yarns.
It is applicable to all types of yarn, including single yarns, double and cabled yarns, textured yarns, rovings
and staple-fibre yarns.
2 Normative references
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.
ISO 291, Plastics — Standard atmospheres for conditioning and testing
ISO 1887, Textile glass — Determination of combustible-matter content
ISO 3344, Reinforcement products — Determination of moisture content
ISO 10548:2002, Carbon fibre — Determination of size content
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
linear density
〈of a yarn〉 mass per unit length of the yarn, with or without size
NOTE The unit generally used is the tex, which corresponds to 1 g per kilometre of yarn.
4 Principle
A yarn test specimen of known length, with or without size, is weighed and the mass per unit length calculated.
In the case where the yarn must be desized, this is done by extraction and drying (in the case of aramid fibre),
by calcination (in the case of glass fibre) or by extraction or pyrolysis (in the case of carbon fibre).
In the case of carbon-fibre yarns, the linear density of the desized yarn may also be calculated from the linear
density of th
