Textile fibres - Determination of breaking force and elongation at break of individual fibres (ISO 5079:2020)
This document specifies the method and conditions of test for the determination of the breaking force and elongation at break of individual fibres in the conditioned or wet state.
The determination of these fibre properties, when carried out on different kinds of testing equipment, will not generally give identical results. To avoid such differences, this document is restricted to the use of constant-rate-of-extension testing machine.
It is applicable to all fibres, including crimped fibres, provided that the length of fibre available enables the gauge length specified in this document.
NOTE For natural fibres (especially wool and cotton), the breaking test most commonly performed is that of bundles of fibres (see ISO 3060 and IWTO 32‑82).
Textilfasern - Bestimmung der Höchstzugkraft und Höchstzugkraftdehnung an einzelnen Fasern (ISO 5079:2020)
Dieses Dokument legt das Verfahren und die Prüfbedingungen zur Bestimmung der Höchstzugkraft und Höchstzugkraftdehnung an einzelnen Fasern im konditionierten oder nassen Zustand fest.
Die Bestimmung dieser Fasereigenschaften führt im Allgemeinen nicht zu den gleichen Ergebnissen, wenn die Prüfung mit Geräten verschiedener Art durchgeführt wird. Um derartige Unterschiede zu vermeiden, ist dieses Dokument auf Prüfmaschinen mit konstanter Dehnungsgeschwindigkeit beschränkt.
Es ist anzuwenden für alle Fasern, einschließlich der gekräuselten Fasern, vorausgesetzt, dass die zur Verfügung stehende Faserlänge für die in diesem Dokument festgelegte Einspannlänge ausreicht.
ANMERKUNG Bei Naturfasern (insbesondere Wolle und Baumwolle) wird die Zugprüfung hauptsächlich an Faserbündeln vorgenommen (siehe ISO 3060 und IWTO 32 82).
Fibres textiles - Détermination de la force de rupture et de l'allongement de rupture des fibres individuelles (ISO 5079:2020)
Le présent document spécifie une méthode et des conditions d'essai pour la détermination de la force de rupture et de l'allongement de rupture de fibres individuelles à l'état conditionné ou mouillé.
La détermination de ces propriétés des fibres, lorsqu'elle est effectuée sur différentes sortes d'appareils d'essai, ne donne généralement pas des résultats identiques. Afin d'éviter ces différences, le présent document s'est limité à l'appareil d'essai à vitesse constante d'allongement.
Il est applicable à toutes fibres, y compris les fibres frisées, à condition que leur longueur disponible permette d'utiliser la longueur entre repères spécifiée dans le présent document.
NOTE Pour des fibres naturelles (en particulier la laine et le coton), l'essai de rupture le plus couramment réalisé est celui de faisceaux de fibres (voir ISO 3060 et IWTO 32‑82).

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).

1 Scope
This document specifies the method and conditions of test for the determination of the breaking force
and elongation at break of individual fibres in the conditioned or wet state.
The determination of these fibre properties, when carried out on different kinds of testing equipment,
will not generally give identical results. To avoid such differences, this document is restricted to the use
of constant-rate-of-extension testing machine.
It is applicable to all fibres, including crimped fibres, provided that the length of fibre available enables
the gauge length specified in this document.
NOTE For natural fibres (especially wool and cotton), the breaking test most commonly performed is that of
bundles of fibres (see ISO 3060 and IWTO 32-82).
