Rubber- or plastics-coated fabrics - Determination of resistance to liquids (ISO 6450:2021)
This document specifies two methods of evaluating the resistance of rubber- or plastics-coated fabrics to the action of liquids by measurement of selected properties of the materials before and after immersion in selected liquids.
The two methods are as follows:
— Method A: total immersion with liquid;
— Method B: one surface side immersion with liquid.
Mit Kautschuk oder Kunststoff beschichtete Textilien - Bestimmung der Flüssigkeitsbeständigkeit (ISO 6450:2021)
Dieses Dokument legt zwei Verfahren zum Beurteilen der Beständigkeit von mit Kautschuk oder Kunststoff beschichteten Textilien gegen die Einwirkung von Flüssigkeiten durch Messung ausgewählter Eigenschaften der Materialien vor und nach dem Eintauchen in ausgewählte Flüssigkeiten fest.
Die zwei Verfahren sind die folgenden:
- Verfahren A: vollständiges Eintauchen in die Flüssigkeit;
- Verfahren B: oberflächenseitiges Eintauchen in die Flüssigkeit.
WARNUNG - Personen, die dieses Dokument verwenden, sollten mit der normalen Laborpraxis vertraut sein. In diesem Dokument werden nicht alle Sicherheitsprobleme behandelt, die bei An-wendung der Norm auftreten können. Es liegt in der Verantwortung des Anwenders, geeignete Sicherheits- und Gesundheitspraktiken festzulegen und Übereinstimmung mit Bedingungen natio-naler Rechtsvorschriften sicherzustellen.
Supports textiles revêtus de caoutchouc ou de plastique - Détermination de la résistance aux liquides (ISO 6450:2021)
Le présent document spécifie deux méthodes d’évaluation de la résistance des supports textiles revêtus de caoutchouc ou de plastique par rapport à l’action des liquides, consistant à mesurer les propriétés sélectionnées des matériaux avant et après immersion dans des liquides définis.
Ces deux méthodes sont les suivantes:
— Méthode A: immersion totale dans un liquide;
— Méthode B: immersion d’un côté de la surface dans un liquide.

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 www .iso .org/

This document was prepared by Technical Committee ISO/TC 45, Rubber and rubber products,
Subcommittee SC 4, Products (other than hoses), in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 248, Textile 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 6450:2005), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— one surface side immersion with liquid has been added as method B;
— in Clause 10 e), the requirement to include CAS registry number when it is available has been added.
Any feedback or questions on this document should be directed to the user’s national standards body. A
