Textiles - Yarns from packages - Determination of single-end breaking force and elongation at break using constant rate of extension (CRE) tester (ISO 2062:2009)

This International Standard specifies methods for the determination of the breaking force and elongation at break of textile yarns taken from packages. Four methods are given: - A: manual; specimens are taken directly from conditioned packages; - B: automatic; specimens are taken directly from conditioned packages; - C: manual; relaxed test skeins are used after conditioning; - D: manual; specimens are used after wetting. Method C is used in cases of dispute regarding elongation at break of the yarn. This International Standard specifies methods using constant rate of specimen extension (CRE) tensile testers. Testing on the now obsolete constant rate of travel (CRT) and constant rate of loading (CRL) instruments is covered, for information, in Annex A, in recognition of the fact that these instruments are still in use and can be used by agreement. This International Standard applies to all types of yarns, except glass, elastomeric, aramid, high molecular polyethylene (HMPE), ultra high molecular polyethylene (UHMPE), ceramic and carbon yarns and polyolefin tape. This International Standard is applicable to yarns from packages but can be applied to yarns extracted from fabrics, subject to agreement between the interested parties. This International Standard is intended for the single-end (single-strand) testing of yarns.

Textilien - Garne von Aufmachungseinheiten - Bestimmung der Höchstzugkraft und Höchstzugkraftdehnung von Garnabschnitten unter Verwendung eines Prüfgeräts mit konstanter Verformungsgeschwindigkeit (CRE) (ISO 2062:2009)

1.1   Diese Internationale Norm legt Verfahren für die Bestimmung der Höchstzugkraft und der Höchstzugkraftdehnung von textilen Garnen fest, welche Aufmachungseinheiten entnommen werden.
Vier Verfahren sind festgelegt:
   A: manuelles Verfahren; Messproben werden direkt den klimatisierten Aufmachungseinheiten ent¬nommen.
   B: automatisches Verfahren; Messproben werden direkt den klimatisierten Aufmachungseinheiten ent¬nommen.
   C: manuelles Verfahren; es werden spannungsfreie klimatisierte Prüfstränge verwendet.
   D: manuelles Verfahren; es werden benetzte Prüfstränge verwendet; Nassprüfung.
1.2   Verfahren C sollte in strittigen Fällen bezüglich der Höchstzugkraftdehnung der Garne verwendet werden.
ANMERKUNG 1   Es ist zu erwarten, dass die Verfahren A, B und C für die Garnfestigkeit zu den gleichen Ergebnissen führen, Verfahren C könnte jedoch zu etwas genaueren (und höheren) Dehnungswerten als A oder B führen. Verfahren D wird wahrscheinlich zu Ergebnissen führen, welche für Höchstzugkraft und Höchstzugkraftdehnung von den Ergebnissen nach Verfahren A, B und C abweichen.
1.3   Diese Internationale Norm legt Verfahren zur Verwendung von Zugprüfgeräten mit konstanter Verfor¬mungsgeschwindigkeit der Messproben (CRE) fest. Eine Prüfung auf den nun veralteten Geräten mit konstanter Abzugsgeschwindigkeit (CRT) und konstanter Belastung (CRL) wird zur Information in Anhang A erläutert, womit die Tatsache Berücksichtigung findet, dass diese Geräte noch immer in Gebrauch sind und, wenn dies vereinbart wird, verwendet werden dürfen.
1.4   Diese Internationale Norm gilt für alle Arten von Garnen, ausgenommen Glasgarne, Elastogarne, Aramidgarne, keramische Garne, Kohlenstoffgarne, Polyethylengarne mit hohem (HMPE) oder ultrahohem Molekulargewicht (UHMPE) und Polyolefin-Bandgarne.
ANMERKUNG 2   Ein Verfahren zur Prüfung von Glasgarnen ist in ISO 3341:1984 "Textilglas — Garne — Bestimmung der Höchstzugkraft und Höchstzugkraftdehnung" enthalten.

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 2062 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 23, Fibres and yarns.

Introduction
In the 1950s and 1960s when this International Standard was first prepared, three types of tensile testers
were in wide use: constant rate of specimen extension (CRE), constant rate of travel (CRT) and constant rate
of loading (CRL). It was therefore advisable to state the rate of operation in a way which would be common to
all three types of tester. In addition, the best possible agreement was sought between the test results of the
three types of tester. Consequently, the principle of constant time to break was adopted, and 20 s to break
was chosen for this International Standard and also for a number of national standards.
In the early 1990s, CRE testers were recognized as the best type. As CRT and CRL testers were still in use
internationally, the procedure for using them was included in an informative annex. There is no assurance that
the results from the three types of tester will agree. This International Standard considers CRE testers only, so
the time-to-break principle was no longer needed and a simpler statement of rate of extension was used. The
rate of extension of 100 % per minute has been adopted as standard, but higher rates were permitted by
agreement for automatic testers.
CRT and CRL testers are now considered to be obsolete. The methods of using them are deprecated and
their inclusion in informative Annex A does not have an influence on the status of this International Standard.

INTERNATIONAL STANDARD ISO 2062:2009(E)

Textiles — Yarns from packages — Determination of single-end
breaking force and elongation at break using constant rate of
extension (CRE) tester
1 Scope
1.1 This International Standard specifies methods for the determination of the breaking force and
elongation at break of textile yarns taken from packages.
Four methods are given:
⎯ A: manual; specimens are taken directly from conditioned packages;
⎯ B: automatic; specimens are taken directly from conditioned packages;
⎯ C: manual; relaxed test skeins are used after conditioning;
⎯ D: manual; specimens are used after wetting.
1.2 Method C is used in cases of dispute regarding elongation at break of the yarn.
NOTE Methods A, B and C are expected to give the same results for yarn strength, but Method C might give
somewhat truer (and higher) values of elongation than A or B. Method D is likely to give results differing, for both breaking
force and elongation at break, from those obtained by methods A, B or C.
1.3 This International Standard specifies methods using constant rate of specimen extension (CRE) tensile
testers. Testing on the now obsolete constant rate of travel (CRT) and constant rate of loading (CRL)
instruments is covered, for information, in Annex A, in recognition of the fact that these instruments are still in
use and can be used by agreement.
1.4 This International Standard applies to all types of yarns, except glass, elastomeric, aramid, high
molecular polyethylene (HMPE), ultra high molecular polyethylene (UHMPE), ceramic and carbon yarns and
polyolefin tape.
NOTE A method for the testing of glass yarns is given in ISO 3341.
1.5 This International Standard is applicable to yarns from packages but can be applied to yarns extracted
from fabrics, subject to agreement between the interested parties.
1.6 This International Standard is intended for the single-end (single-strand) testing of yarns.
NOTE The skein method of testing is given in ISO 6939.

4 Principle
A specimen of yarn is extended until rupture by a suitable mechanical device, and the breaking force and
elongation at break are recorded. A constant rate of extension of 100 % per minute (based on the gauge
length) is used, but higher or lower rates are permitted by agreement. Two gauge lengths are permitted:
usually 500 mm (with a rate of extension of 500 mm/min), and exceptionally 250 mm (with a rate of extension
of 250 mm/min).
5 Apparatus and reagents
5.1 Constant rate of specimen extension (CRE) tester, which complies with the following requirements.
The tester shall be capable of being set at gauge lengths of 500 mm ± 2 mm or 250 mm ± 1 mm, or preferably
both.
The constant rate of extension of the moving clamp shall be 500 mm/min ± 10 mm/min or
