ISO 9163:2005(E)
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 9163 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 9163:1996), which has been technically revised,
as follows:
— The reference method remains essentially the same, with a few corrections, as in ISO 9163:1996.
— The so-called “fast method” described in ISO 9163:1996 has been deleted because it was no longer used.
It has been replaced by a method which needs far less time and gives results consistent with the reference
method.

INTERNATIONAL STANDARD ISO 9163:2005(E)
Textile glass — Rovings — Manufacture of test specimens and
determination of tensile strength of impregnated rovings
1Scope
This International Standard specifies two methods for the determination of the tensile stress at break of an
impregnated roving:
— a reference method using test specimens produced with moulded epoxy tabs;
— a short method using test specimens with no tabs or simple cardboard or composite tabs.
The methods are applicable to both assembled (multistrand) and direct (multifilament) rovings; nevertheless the
reference method may be used for various linear densities, but the short method is described for 1 200 tex
rovings only, which is the linear density that allows the fibres in the roving to spread out most easily during
impregnation.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 472 and the following apply.

ISO 9163:2005(E)
3.1
breaking force
force or load required to rupture a test specimen in a tensile test, usually expressed in newtons
3.2
gauge length
nominal length between the spines of contact of an extensometer (expressed in millimetres), by reference to
which the length increase due to a tensile force is determined
3.3
relative elongation
ratio of the increase in length (expressed in millimetres) between the spines of contact of an extensometer,
resulting from application of a tensile force, to the gauge length of the extensometer (also expressed in
millimetres)
3.4
breaking stress
ratio (expressed in megapascals) of the breaking force (expressed in newtons) to the cross-sectional area of a
roving (expressed in square millimetres)
3.5
loading stress
ratio (expressed in megapascals) of the tensile force applied to a roving during a tensile test (expressed in
newtons) to the cross-sectional area of the roving (expressed in square millimetres)
NOTE The force experienced by the resin can be neglected.
3.6
cross-sectional area
S
area of the cross-section of a roving given, in square millimetres, by the formula:
−3
ρ × 10
l
(1)
ρ
g
where
ρ is the exact linear density of the unsized roving, in tex;
l
is the density of the glass constituting the roving, in grams per cubic centimetre.
ρ
g
3.7
proportional limit
greatest stress (expressed in megapascals) for which the relative elongation is proportional to the applied force
4Principle
A specimen of impregnated roving is subjected to tensile loading to rupture using a suitable mechanical
apparatus, and the breaking stress of the specimen determined.
5 Sampling and conditioning
Carry out sampling in accordance with ISO2859-1, using the “inspection by attributes” method, or in
accordance with ISO 3951-1, using the “inspection by variables” method in order to minimize the number of
elementary units (packages) to be selected.
Condition the packages selected for at least 12 h in one of the standard atmospheres given in ISO 291.

6 Production of test specimens — Reference method
6.1 Apparatus
Ordinary laboratory apparatus, plus the following:
6.1.1 Impregnation apparatus (see Figure 1), including the following elements:
6.1.1.1 Reel, equipped with a tension-regulating system capable of maintaining the roving under a tension
between 0,2 N and 20 N by positioning the tensioning bars (see Figure2) to obtain a correct level of
impregnation. The tension can be adjusted by measuring it with a tension-measuring instrument between the
reel and the entrance guide.
