Tissue paper and tissue products - Part 12: Determination of tensile strength of perforated lines and calculation of perforation efficiency (ISO 12625-12:2023)
This document specifies a test method for the determination of the tensile strength of perforated lines of tissue paper. It uses a tensile-testing apparatus operating with a constant rate of elongation.
This method is only used for measuring machine-direction tensile strength, that is for cross-direction perforations on tissue paper.
The calculation of perforation efficiency is also specified in this document.
Tissue-Papier und Tissue-Produkte - Teil 12: Bestimmung der breitenbezogenen Bruchkraft von Perforationslinien und Berechnung der Perforationseffizienz (ISO 12625‑12:2023)
Dieses Dokument legt ein Prüfverfahren für die Bestimmung der breitenbezogenen Bruchkraft von Perforationslinien von Tissue-Papier fest. Hierfür wird ein Zugprüfgerät benutzt, das mit einer konstanten Dehnungs¬geschwindigkeit arbeitet.
Dieses Verfahren wird nur für die Messung der breitenbezogenen Bruchkraft in Maschinenlaufrichtung angewendet, demzufolge also für die Perforationen von Tissue-Papier in Maschinenquerrichtung.
Die Berechnung der Perforationseffizienz wird ebenfalls in diesem Dokument festgelegt.
Papier tissue et produits tissues - Partie 12: Détermination de la résistance à la rupture par traction des lignes de prédécoupe et calcul de l'efficacité des perforations (ISO 12625-12:2023)
Le présent document spécifie une méthode d’essai permettant de déterminer la résistance à la rupture par traction des lignes de prédécoupe du papier tissue. Cette méthode implique l’utilisation d’un appareil d’essai de traction fonctionnant à un gradient d’allongement constant.
Cette méthode est utilisée uniquement pour mesurer la résistance à la rupture par traction dans le sens machine, c’est-à-dire pour des lignes de prédécoupe dans le sens travers du papier tissue.
Le calcul de l’efficacité des perforations est également indiqué dans le présent document.
Tissue papir in proizvodi iz tissue papirja - 12. del: Ugotavljanje natezne trdnosti perforacije in izračun učinka perforacije (ISO 12625-12:2023)
Standard ISO 12625-12:2010 določa preskusno metodo za ugotavljanje natezne trdnosti perforacije pri papirju za robčke. Uporablja napravo za preskušanje natega, ki deluje s stalno hitrostjo raztezanja.
Ta metoda se uporablja samo za merjenje natezne trdnosti v smeri obdelave, to je za perforacije v navzkrižni smeri na papirju za robce.
Izračun učinkovitosti perforacije je podan v standardu ISO 12625-12:2010.

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 document 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).
