Rubber and plastics hoses - Assessment of ozone resistance under static conditions (ISO 7326:2006)
ISO 7326:2006 specifies five methods for determining the ozone resistance of the outer covers of hoses:
method 1, for bore sizes up to and including 25 mm, carried out on the hose itself;
method 2, for bore sizes greater than 25 mm, carried out on a test piece from the hose wall;
method 3, for bore sizes greater than 25 mm, carried out on a test piece from the cover;
method 4, for all bore sizes, carried out on the hose itself;
method 5, for all bore sizes, carried out on hoses that are expandable, for example textile-reinforced hoses.
Gummi- und Kunststoffschläuche - Bestimmung der Ozonbeständigkeit unter statischen Bedingungen (ISO 7326:2006)
Diese Internationale Norm definiert fünf Verfahren für die Bestimmung der Ozonbeständigkeit der Außenschicht
von Schläuchen:
- Verfahren 1, für Innendurchmesser bis zu und bis einschließlich 25 mm, das am Schlauch selbst ausgeführt
wird;
- Verfahren 2, für Innendurchmesser größer als 25 mm, durchgeführt an einem Prüfkörper aus der
Schlauchwand;
- Verfahren 3, für Innendurchmesser größer als 25 mm, durchgeführt an einem Prüfkörper aus der Außenschicht;
- Verfahren 4, für alle Innendurchmesser, das am Schlauch selbst ausgeführt wird;
- Verfahren 5, für alle Innendurchmesser, durchgeführt an dehnbaren Schläuchen, z. B. Textilverstärkte
Schläuche.
ANMERKUNG Für Schläuche mit einvulkanisierten Armaturen, von welchen es nicht möglich ist, Prüfkörper zu
entnehmen, kann die Ozonbeständigkeitsprüfung an Platten nach ISO 1431-1 durchgeführt werden unter Verwendung
von Prüfstücken der entsprechenden Polymermischung und gleichem Vulkanisationsgrad.
Tuyaux en caoutchouc et en plastique - Évaluation de la résistance à l'ozone dans des conditions statiques (ISO 7326:2006)
L'ISO 7326:2008 spécifie cinq méthodes pour la détermination de la résistance à l'ozone des revêtements extérieurs des tuyaux:
méthode 1, pour des dimensions d'alésage inférieures ou égales à 25 mm, réalisée sur le tuyau lui-même;
méthode 2, pour des dimensions d'alésage supérieures à 25 mm, réalisée sur une éprouvette prélevée dans la paroi du tuyau;
méthode 3, pour des dimensions d'alésage supérieures à 25 mm, réalisée sur une éprouvette prélevée dans le revêtement du tuyau;
méthode 4, pour toutes les dimensions d'alésage, réalisée sur le tuyau lui-même;
méthode 5, pour toutes les dimensions d'alésage, réalisée sur des tuyaux qui sont extensibles, par exemple des tuyaux renforcés textile.
