Thermoplastics valves - Fatigue strength - Test method (ISO 8659:2020)
This document specifies the endurance test necessary to confirm the ability of hand-operated plastics
valves to withstand prolonged use, with repeated opening and closure. It does not specify the ability of
valves to withstand adverse conditions, in particular those of chemically aggressive fluid media and/or
environments, or excessive fluid velocities and cavitation.
NOTE Concerning the chemical aggression of the materials, a classification table is reported in
ISO/TR 10358[1].
This document includes values of the parameters necessary for the proper performance of the
endurance test, with the reservation that the parameters are different in particular product standards
(see 5.1).
Armaturen aus Thermoplasten - Ermüdungsfestigkeit - Prüfverfahren (ISO 8659:2020)
Dieses Dokument legt die Dauerprüfung fest, die notwendig ist, um sicherzustellen, dass handbetätigte Armaturen aus Kunststoff geeignet sind, einer längeren Gebrauchsdauer mit wiederholtem Öffnen und Schließen standzuhalten. Es werden keine Anforderungen festgelegt für die Widerstandsfähigkeit von Armaturen gegenüber ungünstigen Bedingungen, insbesondere chemisch aggressiven Flüssigkeiten und/oder Umgebungen oder übermäßige Fließgeschwindigkeiten und Kavitation.
ANMERKUNG Zur chemischen Beständigkeit der Werkstoffe ist eine Klassifikationstafel in ISO/TR 10358 [1] angegeben.
Dieses Dokument enthält Prüfparameter, die notwendig für eine ordnungsgemäße Durchführung der Dauerprüfung sind, mit dem Vorbehalt, dass die Prüfparameter in den einzelnen Produktnormen abweichen (siehe 5.1).
Robinets en matériaux thermoplastiques - Résistance à la fatigue - Méthode d'essai (ISO 8659:2020)
Le présent document spécifie les essais de fatigue nécessaires pour confirmer l'aptitude des appareils de robinetterie en matières plastiques manoeuvrés à la main à résister à un usage prolongé, avec ouvertures et fermetures répétées. Il ne spécifie pas l'aptitude des appareils de robinetterie à résister à des conditions défavorables, en particulier celles de fluides et/ou environnements chimiquement agressifs, ou des vitesses excessives des fluides et la cavitation.
NOTE En ce qui concerne l'aggression chimique des matériaux, un tableau de classification est donné dans l'ISO/TR 10358[1].
Le présent document intègre les valeurs des paramètres nécessaires pour une performance correcte de l'essai de fatigue, sous réserve que les paramètres sont différents dans les normes de produits particulières (voir 5.1).
