Nonwovens - Test methods - Part 3: Determination of tensile strength and elongation at break using the strip method (ISO 9073-3:2023)

This document specifies a test method for the determination of the breaking force and elongation of nonwovens using a strip method in conditioned or wet state. This test method describes two procedures, Option A (width of test specimen: 25 mm) and Option B (width of test specimen: 50 mm).
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 3: Bestimmung der Höchstzugkraft und der Höchstzugkraftdehnung (ISO 9073‑3:2023)

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Höchstzugkraft und der Höchstzugkraftdehnung von vorbehandelten bzw. nassen Vliesstoffen in einem Streifenzugversuch fest. Dieses Prüfverfahren beschreibt zwei Verfahren, Option A (Breite der Messprobe: 25 mm) und Option B (Breite der Messprobe: 50 mm).
Dieses Dokument legt Verfahren unter Verwendung von Zugprüfgeräten mit konstanter Verformungsgeschwindigkeit (en: constant rate of specimen extension, CRE) fest. Geräte mit konstanter Lastgeschwindigkeit (en: constant rate of loading, CRL) 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 Sicherheits- und Gesundheitsschutzmaßnahmen vorzusehen und im Vorfeld die Anwendbarkeit von einschränkenden Vorschriften zu klären. Es wird erwartet, dass die Person, die diese Prüfung durchführt, in allen Aspekten dieses Verfahrens umfassend geschult wurde.

Nontissés - Méthodes d'’essai - Partie 3: Détermination de la résistance à la traction et de l'allongement à la rupture par la méthode sur bande (ISO 9073-3:2023)

Le présent document spécifie une méthode d’essai pour la détermination de la force de rupture et de l’allongement des nontissés après conditionnement ou à l’état humide, par la méthode sur bande. Cette méthode d’essai décrit deux modes opératoires, nommés option A (épaisseur de l’éprouvette d’essai: 25 mm) et option B (épaisseur de l’éprouvette d’essai: 50 mm).
Le présent document spécifie des méthodes utilisant des appareils d’essai de traction à vitesse constante d’allongement (CRE) de l’éprouvette. À titre d’information, les appareils à gradient de force constant (GFC) sont couverts dans l’ISO 2062:2009, Annexe A, étant donné que ces instruments sont toujours utilisés et que leur utilisation peut faire l'objet d'un accord entre les parties intéressées.

Vlaknovine - Preskusne metode - 3. del: Ugotavljanje natezne trdnosti in pretržnega raztezka pri pretrganju s tračno metodo (ISO 9073-3:2023)

Vršenje vzdolžne sile na preskušanca določene dolžine in debeline pri konstantni hitrosti raztezanja. Določanje vrednosti za utržno trdnost in raztezek na podlagi ugotovljene krivulje sila-raztezek. V tem delu standarda ISO 9073 so določene zahteve za izpolnitev posebnih potreb vlakovin, ki so drugačne od zahtev, navedenih v standardu ISO 5081. Nanašajo se na a) drugačen postopek vzorčenja; b) konstantno hitrost raztezanja (100 mm/min).
