ISO 13936-3:2005(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 13936-3 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 24, Conditioning
atmospheres and physical tests for textile fabrics.
ISO 13936 consists of the following parts, under the general title Textiles — Determination of the slippage
resistance of yarns at a seam in woven fabrics:
 Part 1: Fixed seam opening method
 Part 2: Fixed load method
 Part 3: Needle clamp needle

INTERNATIONAL STANDARD ISO 13936-3:2005(E)

Textiles — Determination of the slippage resistance of yarns at
a seam in woven fabrics —
Part 3:
Needle clamp method
1 Scope
This part of ISO 13936 describes a method for the determination of the resistance offered by the yarns of a
woven fabric to slippage while being held in a needle clamp under conditions of stress.
This method provides a means to negate variations introduced by seam preparation or sewing thread variation
that can have a marked influence on test results.
This method is not applicable to stretch fabrics or for industrial fabric, e.g. beltings.
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 139, Textiles — Standard atmospheres for conditioning and testing
ISO 7500-1, Metallic materials — Verification of static uniaxial testing machines — Part 1:
Tension/compression testing machines — Verification and calibration of the force-measuring system
ISO 10012-1, Quality assurance requirements for measuring equipment — Part 1: Metrological confirmation
system for measuring equipment
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
constant rate-of-extension testing machine
tensile testing machine having one clamp fixed whilst the other is moving with a constant speed throughout
the test where the entire testing system is virtually free from deflection
3.2
strip test
tensile test for which the full width of the test specimen is gripped in the jaws
ISO 13936-3:2005(E)
3.3
yarn slippage
movement in a woven fabric of weft yarns over warp yarn (or warp yarns over weft yarns) as a result of a
pulling action
NOTE Seam slippage is a fabric property not to be confused with seam strength.
3.4
warp slippage
slipping of warp yarns over weft yarns, during which the warp yarns are at right angles to the direction of pull
3.5
weft slippage
slipping of weft yarns over warp yarns, during which the weft yarns are at right angles to the direction of pull
3.6
gauge length
distance between the two effective clamping points of the testing device
4 Principle
A pinned and an unpinned test specimen are separately extended by using a tensile testing machine fitted
with a needle-clamping device for the pinned specimen and conventional jaws for the unpinned specimen, to
produce, in the case of the use of a chart recorder, two force/extension curves originating from the same
abscissa. The yarn slippage, expressed in millimetres, is determined by comparing the two curves at specified
force applications.
5 Apparatus and materials
5.1 CRE machine, having the following general characteristics.
a) The tensile-testing machine shall be provided with a means for indicating or recording both the maximum
force applied to the test specimen in stretching it to rupture and the corresponding extension of the test
specimen.
b) Under conditions of the use, the accuracy of the apparatus shall be at least class 1 in accordance with
ISO 7500-1. The error of indicated or recorded maximum force at any point in the range in which the
machine is used shall not exceed ± 1 %, and the error of the indicated or recorded jaw separation shall
not exceed ± 1 mm.
c) If recording of force and elongation is obtained by means of data acquisition boards and software, the
frequency of data collection shall be at least 8 per second. If the machine is not equipped with data
acquisition boards and applicable software, a chart recorder is necessary.
d) The machine shall be capable of constant rates of extension of 50 mm/min ± 5 mm/min (and
20 mm/min ± 2 mm/min).
e) The machine shall be capable of gauge lengths of (100 ± 1) mm and (20 ± 1) mm.
f) Metrological confirmation of tensile testing machine shall be in accordance with ISO 10012-1.
5.2 Needle-clamp clamping device, with a row of needles on one side and corresponding holes on the
other as shown in Figure 1.
The number and characteristics of these needles depend on the application of the fa
