Textiles - Determination of the elasticity of fabrics - Part 2: Multiaxial tests (ISO 20932-2:2018)

This document specifies the test methods which can be used to measure elasticity and related properties of fabrics when they undergo a deformation of their surface. Two methods are specified: a dynamic method (method A) and a static method (method B). This document does not apply to narrow fabrics.
The results obtained cannot be compared. The choice of test method are agreed between parties and indicated in the test report.

Textilien - Bestimmung der Elastizität von textilen Flächengebilden - Teil 2: Multiaxiale Prüfungen (ISO 20932-2:2018)

Dieses Dokument legt die Prüfverfahren fest, die zur Messung der Elastizität und zugehöriger Eigenschaften von textilen Flächengebilden angewendet werden können, wenn deren Oberfläche einer Verformung ausgesetzt wird. Zwei Verfahren werden festgelegt: ein dynamisches Verfahren (Verfahren A) und ein statisches Verfahren (Verfahren B). Dieses Dokument ist nicht anzuwenden für Schmaltextilien.
Die erhaltenen Ergebnisse können nicht verglichen werden. Die Wahl des Prüfverfahrens wird zwischen den Parteien vereinbart und im Prüfbericht angegeben.

Textiles - Détermination de l'élasticité des étoffes - Partie 2: Essais multiaxiaux (ISO 20932-2:2018)

Le présent document spécifie les méthodes d'essai qui peuvent être appliquées pour mesurer l'élasticité et les propriétés afférentes des étoffes lorsqu'elles sont soumises à la déformation de leur surface. Il spécifie deux méthodes: une méthode dynamique (méthode A) et une méthode statique (méthode B). Le présent document ne s'applique pas aux étoffes étroites.
Les résultats obtenus ne peuvent être comparés. Le choix de la méthode fait l'objet d'un accord entre les parties intéressées et est indiqué dans le rapport d'essai.

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 rights identified during the development of the document will be in the Introduction and/or
