Textiles - Seam tensile properties of fabrics and made-up textile articles - Part 2: Determination of maximum force to seam rupture using the grab method (ISO/DIS 13935-2:2025)
ISO 13935-2:2014 specifies methods for the determination of seam maximum force of sewn seams when the force is applied perpendicularly to the seam. ISO 13935-2:2014 describes the method known as the grab test.
The method is mainly applicable to woven textile fabrics, including fabrics which exhibit stretch characteristics imparted by the presence of an elastomeric fibre, mechanical or chemical treatment. It may be applicable to fabrics produced by other techniques. It is not normally applicable to geotextiles, nonwovens, coated fabrics, textile-glass woven fabrics and fabrics made from carbon fibres or polyolefin tape yarns.
The sewn fabrics may be obtained from previously sewn articles or may be prepared from fabric samples, as agreed by the parties interested in the results.
This method is applicable to straight seams only and not to curved seams.
The method is restricted to the use of constant rate of extension (CRE) testing machines.

L'ISO 13935-2:2014 spécifie une méthode pour la détermination de la force maximale des coutures avec application de la force perpendiculairement à la couture. L'ISO 13935-2:2014 décrit la méthode dite essai d'arrachement.
La présente méthode d'essai s'applique essentiellement aux étoffes tissées, y compris les étoffes qui présentent des caractéristiques d'extensibilité induites par la présence de fibres élastomères, par traitement mécanique ou chimiques. Elle peut être appliquée aux étoffes produites par d'autres techniques. Elle ne s'applique normalement pas aux géotextiles, aux non-tissés, aux étoffes revêtues, aux tissus en verre textile et aux étoffes en fibres de carbone ou en fils provenant de lames de polyoléfine.
Les étoffes cousues peuvent être obtenues à partir d'articles préalablement cousus ou peuvent être préparées à partir d'échantillons selon accord entre les parties intéressées aux résultats de l'essai.
La présente méthode d'essai s'applique aux coutures droites uniquement et non pas aux coutures courbes.
La présente méthode permet uniquement l'utilisation d'appareils d'essai à vitesse constante d'allongement.

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of any patent

Introduction
This document has been prepared in the context of several test methods for determination of certain
mechanical properties of textiles using mainly tensile testing machines, e.g. tensile properties, seam tensile
properties, tear properties, seam slippage. The procedure for these standards agrees where appropriate. The
results obtained by one of the methods should not be compared with those obtained by the other methods.
See Bibliography for informative references.
Where it is intended to compare the seam maximum force values of sewn seams with the fabric maximum
force, it is important to use the same type of test, test conditions and test specimens in the tests in this

document and ISO 13934-2:2014 (see Bibliography).
