Rubber and plastics hoses and hose assemblies - Determination of resistance to vacuum (ISO 7233:2006)
ISO 7233:2006 specifies three methods for determining the resistance to vacuum of hoses and hose assemblies manufactured from plastic or rubber. Applicable dimensions of hoses for each method are as follows:
method A -- for hoses of nominal bore up to and including 80 mm;
method B -- for hoses of nominal bore greater than 80 mm;
method C -- for hoses of all dimensions.
Methods A and B can also be used to check the adhesion of the lining to the reinforcement (delamination) in a length of hard-wall hose or hose assembly.
Gummi- und Kunststoffschläuche und Schlauchleitungen - Bestimmung der Beständigkeit gegen Vakuum (ISO 7233:2006)
Diese Internationale Norm legt drei Verfahren zur Bestimmung der Vakuumbeständigkeit von Schläuchen und Schlauchleitungen gefertigt aus Kunststoff oder Gummi fest. Geeignete Abmessungen von Schläuchen für jedes Verfahren sind die im Folgenden genannten:
Verfahren A : Für Schläuche mit einem Nenn-Innendurchmesser bis einschließlich 80 mm;
Verfahren B : Für Schläuche mit einem Nenn-Innendurchmesser größer 80 mm;
Verfahren C : Für Schläuche aller Abmessungen.
Verfahren A und B können auch zur Prüfung der Anhaftung zwischen innerer Schicht und Verstärkungselement (Ablösung) in der Länge eines Schlauches mit Wendel oder einer Schlauchleitung genutzt werden
Tuyaux et flexibles en caoutchouc et en plastique - Détermination de la résistance à l'aspiration (ISO 7233:2006)
L'ISO 7233:2006 spécifie trois méthodes pour la détermination de la résistance à l'aspiration des tuyaux et des flexibles fabriqués à partir de caoutchouc ou de plastique. Les dimensions s'appliquant aux tuyaux pour chaque méthode sont les suivantes:
méthode A — pour tuyaux de diamètre intérieur nominal inférieur ou égal à 80 mm;
méthode B — pour tuyaux de diamètre intérieur nominal supérieur à 80 mm;
méthode C — pour tuyaux de toutes dimensions.
Les méthodes A et B peuvent également être utilisées pour vérifier l'adhérence entre le tube intérieur et le renforcement (délamination) dans une longueur de tuyau ou de flexible de raccordement renforcé.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of
