Rubber- or plastics-coated fabrics - Determination of tear resistance - Part 2: Ballistic pendulum method (ISO 4674-2:2021, Corrected version 2021-11)
This document specifies a method for the determination of tear resistance based on the action of an active force applied to a notched test piece.
The test can be carried out on:
test pieces that have been conditioned in a standard atmosphere; or
test pieces that have undergone pre-treatment, e.g. water immersion.
The results obtained by this method cannot be compared with those obtained by methods involving constant rate of tear.
Mit Kautschuk oder Kunststoff beschichtete Textilien - Bestimmung der Weiterreißfestigkeit - Teil 2: Verfahren mit ballistischem Pendel (ISO 4674-2:2021, korrigierte Fassung 2021-11)
Dieses Dokument legt ein Verfahren zur Bestimmung der Weiterreißfestigkeit, wenn auf einen Probekörper mit einer Einkerbung eine Weiterreißkraft wirkt, fest.
Die Prüfung gilt für:
- Probekörper, die in einem Normalklima konditioniert wurden; oder
- Probekörper, die vorbehandelt wurden, z. B. durch Eintauchen in Wasser.
Die Ergebnisse nach diesem Verfahren können nicht mit Ergebnissen verglichen werden, die bei Verfahren mit konstanter Reißgeschwindigkeit gewonnen wurden.
WARNUNG - Die in diesem Dokument beschriebene Prüfung sollte von erfahrenem Personal durchgeführt werden. In diesem Dokument werden nicht alle Sicherheitsprobleme behandelt, die bei Anwendung der Norm auftreten können. Es liegt in der Verantwortung des Anwenders, geeignete Sicherheits- und Gesundheitspraktiken festzulegen und Übereinstimmung mit Bedingungen nationaler Rechtsvorschriften sicherzustellen.
Supports textiles revêtus de caoutchouc ou de plastique - Détermination de la résistance au déchirement - Partie 2: Méthode au pendule balistique (ISO 4674-2:2021, Version corrigée 2021-11)
Le présent document spécifie une méthode pour la détermination de la résistance à la déchirure fondée sur l’action d’une force active appliquée à une éprouvette entaillée.
Les essais peuvent être pratiqués:
sur des éprouvettes conditionnées dans une atmosphère normale; ou
sur des éprouvettes ayant subi un traitement préalable, par exemple une immersion dans l’eau.
Les résultats obtenus par cette méthode ne peuvent être comparés à ceux obtenus par des méthodes mettant en jeu une vitesse constante de déchirement.

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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

Standardization (CEN) Technical Committee CEN/TC 248, Textiles and textile products, in accordance
with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 4674-2:1998), which has been technically
revised. The main changes compared with the previous edition are as follows:
— in Clause 5, the title has been changed to “Apparatus and reagents” and 5.3, 5.4, and 5.5 have been
added;
— in Clause 6, the title has been changed to “Sampling and preparation of test pieces” and Clause 5 has
been integrated;
— in Clause 7, the test duration has been specified;
— in Clause 8, the title has been changed to “Atmosphere for conditioning and testing” and 8.2 has
been added;
— in Clause 9, the wet test has been specified.
This corrected version of ISO 4674-2:2021 incorporates the following corrections:
— "Dimensions in millimetres" has been added to Figure 1.

Introduction
Tearing is amongst the more usual ways of destruction for many thin materials such as paper, coated or
uncoated textiles, plastics films and leather. Knowledge of the resistance of these materials to this type
of behaviour is therefore very important.
In practice, tearing can result from very different circumstances; hence the large number of test
methods that have been developed in order to predict the beha
