Nonwovens - Test methods - Part 18: Determination of tensile strength and elongation at break using the grab tensile test (ISO 9073-18:2023, Corrected version 2024-05)

This document specifies a test method for the determination of the breaking force of nonwovens using a grab method in conditioned or wet state.
This test method is not applicable to materials which have a high percentage of stretch. Comparing test results from tensile testing machines operating on different principles is not applicable.
This document specifies methods using constant rate of specimen extension (CRE) tensile testers. Constant-rate-of-loading (CRL) instruments is covered, for information, in ISO 2062:2009, Annex A, in recognition of the fact that these instruments are still in use and can be used by agreement.

Vliesstoffe - Prüfverfahren - Teil 18: Bestimmung der Höchstzugkraft und der Höchstzugkraftdehnung von Vliesstoffen mit dem Grab-Zugversuch (ISO 9073-18:2023, korrigierte Fassung 2024-05)

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Höchstzugkraft von Vliesstoffen im vorbehandelten bzw. nassen Zustand mit einem Grab-Zugversuch fest.
Dieses Prüfverfahren ist nicht anwendbar für Materialien mit einer hohen Dehnbarkeit. Ein Vergleich der Prüfergebnisse von Zugprüfmaschinen, die nach unterschiedlichen Prinzipien arbeiten, ist nicht anwendbar.
Dieses Dokument legt Verfahren unter Verwendung von Zugprüfgeräten mit konstanter Verformungsgeschwindigkeit (CRE, en: constant rate of specimen extension) fest. Geräte mit konstanter Lastgeschwindigkeit (CRL, en: constant rate of loading) werden in Anerkennung der Tatsache, dass diese Geräte weiterhin verwendet werden und nach Vereinbarung verwendet werden können, zu Informationszwecken in ISO 2062:2009, Anhang A, behandelt.
SICHERHEITSHINWEIS — Dieses Dokument erhebt nicht den Anspruch, eine vollständige Aufzählung von gegebenenfalls zutreffenden Sicherheitsproblemen zu beinhalten, die mit seiner Anwendung verbunden sind. Es liegt in der Verantwortung des Anwenders dieses Dokuments, geeignete Vorkehrungen für den Arbeits- und Gesundheitsschutz zu treffen und vor der Anwendung festzulegen, welche einschränkenden Vorschriften gelten. Es wird erwartet, dass die Person, die diese Prüfung durchführt, in allen Aspekten dieses Verfahrens umfassend geschult wurde.

Nontissés - Méthodes d’essai - Partie 18: Détermination de la résistance à la traction et de l’allongement à la rupture par l’essai d’arrachement par traction (ISO 9073-18:2023, Version corrigée 2024-05)

Le présent document spécifie une méthode d’essai pour la détermination de la force de rupture des nontissés après conditionnement ou à l’état humide, par une méthode d’arrachement.
Cette méthode d’essai n’est pas applicable aux matériaux ayant un pourcentage élevé d’allongement. La comparaison de résultats d’essais obtenus sur des machines d’essai de traction fonctionnant selon des principes différents n’est pas applicable.
Le présent document spécifie des méthodes utilisant des machines d’essai de traction à vitesse constante d’allongement (CRE) des éprouvettes. À titre d’information, les instruments à vitesse constante de charge (CRL) sont couverts par l’ISO 2062:2009, Annexe A, en reconnaissance du fait que ces instruments sont toujours utilisés et peuvent l’être sur la base d’un accord.

Vlaknovine, netkani materiali - Metode preskušanja - 18. del: Ugotavljanje pretržne sile in raztezka ob pretrgu z nateznim preskusom (grab tensile test) (ISO 9073-18:2023)

Standard ISO 9073-18:2007 določa postopek nateznega preskusa za ugotavljanje pretržne sile trdnosti in raztezka ob pretrgu večine netkanih materialov. Vključuje navodila za preskušanje mokrih vzorcev.
Ta postopek nateznega preskusa se uporablja za večino netkanih materialov, vendar pa se ga ne priporoča za netkane materiale, ki imajo visok odstotek raztezanja.

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.
