Rubber and plastics hoses and hose assemblies - Determination of resistance to vacuum (ISO 7233:2016)
This document 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 7233:2016)
Diese Internationale Norm legt drei Verfahren zur Bestimmung der Beständigkeit von Schläuchen und Schlauchleitungen aus Kunststoff oder Gummi gegen Vakuum fest. Für jedes Verfahren sind im Folgenden die zutreffenden Schlauchmaße angegeben:
- Verfahren A - für Schläuche mit einem Nenn-Innendurchmesser bis einschließlich 80 mm;
- Verfahren B - für Schläuche mit einem Nenn-Innendurchmesser über 80 mm;
- Verfahren C - für alle Schlauchmaße.
Die Verfahren A und B können auch zur Prüfung der Haftung zwischen Innenschicht und Verstärkungselement (Schichtablösung) in der Länge eines Schlauches mit Wendel oder einer Schlauchleitung verwendet werden.
Tuyaux et flexibles en caoutchouc et en plastique - Détermination de la résistance à l'aspiration (ISO 7233:2016)
ISO 7233:2016 spécifie trois méthodes pour la détermination de la résistance à l'aspiration des tuyaux et des flexibles fabriqués à partir de plastique ou de caoutchouc. 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 les 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.
Gumene in polimerne cevi ter cevni priključki - Ugotavljanje odpornosti proti vakuumu (ISO 7233:2016)
Ta dokument določa tri metode za ugotavljanje odpornosti proti vakuumu cevi in cevnih priključkov, izdelanih iz polimerov ali gume. Primerne dimenzije cevi za posamezno metodo
so naslednje:
– metoda A za cevi z nominalnim premerom največ 80 mm;
– metoda B za cevi z nominalnim premerom več kot 80 mm;
– metoda C za cevi vseh dimenzij.
Metodi A in B se lahko uporabljata tudi za preverjanje pritrditve obloge na ojačitev (razslojevanje) v dolžini cevi ali cevnih priključkov s togimi stenami.

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).
