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).

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).
