Tissue paper and tissue products - Part 5: Determination of wet tensile strength (ISO 12625-5:2024)

This document specifies a test method for the determination of the wet tensile strength of tissue paper and tissue products after soaking with water, using a tensile-strength-testing apparatus operating with a constant rate of elongation.
Currently, two types of tensile-strength-testing apparatus are commercially available, one where the test piece is positioned vertically and, for the other, horizontally. This document applies for both. For vertical tensile-strength-testing apparatus, a device that is held in the lower grip of the tensile-strength-testing apparatus, called a Finch Cup, is used to achieve the wetting. For horizontal tensile-strength-testing apparatus, the soaking device is placed between the two clamps.
This document is not applicable to cases where impurities and contraries are determined.

Tissue-Papier und Tissue-Produkte - Teil 5: Bestimmung der breitenbezogenen Nassbruchkraft (ISO 12625-5:2024)

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der breitenbezogenen Nassbruchkraft von Tissue-Papier und Tissue-Produkten nach dem Wässern fest. Hierfür wird ein Zugprüfgerät eingesetzt, das mit konstanter Dehnungsgeschwindigkeit arbeitet.
Momentan sind zwei Arten von Zugprüfgeräten im Handel erhältlich. Bei der einen Art von Zugprüfgerät wird die Probe vertikal, bei der anderen horizontal positioniert. Dieses Dokument ist anwendbar für beide. Bei vertikalen Zugprüfgeräten erfolgt das Wässern mit Hilfe einer Vorrichtung, der so genannten Finch-Eintauchvorrichtung, die in der unteren Klemme des Zugprüfgeräts eingespannt wird. Bei horizontalen Zugprüfgeräten wird die Eintauchvorrichtung zwischen den zwei Klemmen angeordnet.
Dieses Dokument ist nicht anwendbar in Fällen, in denen Unreinheiten und Verunreinigungen bestimmt werden.

Papier tissue et produits tissue - Partie 5: Détermination de la résistance à la rupture par traction à l'état humide (ISO 12625-5:2024)

Le présent document spécifie une méthode d’essai pour la détermination de la résistance à la rupture par traction à l’état humide du papier tissue et des produits tissue, après immersion dans l’eau, en utilisant un appareil d’essai de traction fonctionnant à un gradient d’allongement constant.
Deux types d’appareils d’essai de traction sont actuellement commercialisés, l’un où l’éprouvette est placée à la verticale, et l’autre où l’éprouvette est placée à l’horizontale. Le présent document s’applique aux deux types d’appareils. Les appareils d’essai de traction à position verticale utilisent un dispositif maintenu dans la mâchoire inférieure, appelé dispositif d’immersion Finch, pour réaliser le mouillage. Dans le cas des appareils d’essai de traction en position horizontale, le dispositif d’immersion est placé entre les deux mâchoires.
Le présent document ne s’applique pas dans les cas où les impuretés et les défauts sont déterminés.

Tissue higienski papir in proizvodi iz tissue papirja - 5. del: Ugotavljanje mokre natezne trdnosti (ISO 12625-5:2024)

Standard ISO 12625-5:2016 določa preskusno metodo za ugotavljanje mokre natezne trdnosti tissue papirja in proizvodov iz njega po namakanju v vodi, pri čemer se uporablja naprava za preskušanje natezne trdnosti, ki deluje s stalno hitrostjo raztezanja.
Na tržišču sta trenutno na voljo dve vrsti naprav za preskušanje natezne trdnosti; pri eni je preskušanec postavljen navpično, pri drugi pa vodoravno. Ta dokument se uporablja za obe vrsti naprav. Pri napravi, kjer se natezno trdnost preskuša navpično, močenje zagotavlja pripomoček, ki je v spodnjem primežu naprave in se imenuje Finch Cup. Pri napravi, kjer se natezno trdnost preskuša vodoravno, je naprava za namakanje nameščena med čeljustmi.
V primerih, ko je treba določiti nečistoče in nasprotja v tissue papirju in proizvodih iz njega, se uporablja standard ISO 15755 [6].

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.
