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 2558 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and
reinforcement fibres.
This second edition cancels and replaces the first edition (ISO 2558:1974), of which it constitutes a minor
revision (in 6.1, the minimum distance from the edge of the mat at which test specimens may be cut out has
been increased to 30 mm and, in 6.2, a requirement has been added to condition not only the specimens but
also the styrene before the test).

INTERNATIONAL STANDARD ISO 2558:2010(E)

Textile glass chopped-strand mats for reinforcement of
plastics — Determination of time of dissolution of the binder in
styrene
1 Scope
This International Standard specifies a method of determining the time taken for a tensile load to break the
bond between the strands of a textile glass chopped-strand mat, used for the reinforcement of plastics, which
is immersed in styrene.
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
3 Principle
A test specimen is suspended vertically in pure styrene and a tensile load applied by means of a weight
attached to the Iower end of the specimen. The time taken for the weight to fall a specified distance is
recorded.
NOTE It is possible to distinguish better between mats havi
