Thermoplastics valves - Torque - Test method (ISO 8233:2024)

This document specifies a test method for the determination of the opening, closing and running torque of thermoplastics valves. This test is considered to be performed as part of the initial type testing.
This document applies to all types of thermoplastics valves intended to be used for the transport of fluids.
NOTE 1 Examples of valve types tested with this method are in ISO 16135, ISO 16136, ISO 16138, ISO 16139, ISO 21787, ISO 4437-4, ISO 16486-4, EN 12201-4, EN 1555-4.
It does not specify the relationship between the torque and its possible increase after valve prolonged use at specific working condition or materials wear/chemical aggression.
NOTE 2 Concerning the chemical aggression of the materials, a collection of data is reported in ISO/TR 10358; concerning the endurance test necessary to confirm the ability of hand-operated plastics valves to withstand prolonged use with repeated opening and closure, further information is provided in ISO 8659.

Armaturen aus Thermoplasten - Drehmoment - Prüfverfahren (ISO 8233:2024)

Dieses Dokument legt ein Prüfverfahren zur Bestimmung des Öffnungs-, Schließ- und Betriebsmoments von Armaturen aus Thermoplasten fest.
Dieses Dokument ist anwendbar für alle Typen von handbetätigten Armaturen aus Thermoplasten mit oder ohne Antrieb, die für den Transport von Flüssigkeiten vorgesehen sind.
ANMERKUNG 1   Beispiele für Armaturentypen, die mit diesem Verfahren geprüft wurden, sind in ISO 4437 4, ISO 16135, ISO 16136, ISO 16138, ISO 16139, ISO 16486 4, ISO 21787, EN 1555 4 [13] und EN 12201 4 [14] enthalten.
Dieses Dokument legt nicht die Beziehung zwischen dem Drehmoment und dessen möglicher Erhöhung nach längerem Gebrauch der Armatur bei bestimmten Arbeitsbedingungen oder Verschleiß/chemischer Aggression des Werkstoffs fest.
ANMERKUNG 2   Bezüglich der chemischen Aggression der Werkstoffe ist in ISO/TR 10358 eine Sammlung von Daten über die Dauerprüfung angegeben, die erforderlich ist, um die Fähigkeit handbetätigter Armaturen aus Thermoplasten zu bestätigen, einem längeren Gebrauch bei wiederholtem Öffnen und Schließen standzuhalten. Weitere Informationen enthält ISO 8659.

Robinets en matériaux thermoplastiques - Couple de manoeuvre - Méthode d'essai (ISO 8233:2024)

Le présent document spécifie une méthode d’essai pour la détermination du couple d’ouverture, de fermeture et de fonctionnement des robinets en matériaux thermoplastiques.
Le présent document s’applique à tous les types de robinets en matériaux thermoplastiques manœuvrables manuellement, avec ou sans actionneur, destinés à être utilisés pour le transport des fluides.
NOTE 1        Des exemples de types d'appareils de robinetterie soumis à essai avec la présente méthode sont dans l'ISO 4437-4, l'ISO 16135, l'ISO 16136, l'ISO 16138, l'ISO 16139, l'ISO 16486-4, l'ISO 21787, l'EN 1555-4[13] et l'EN 12201-4[14].
Le présent document ne spécifie pas la relation entre le couple de manœuvre et son augmentation possible après une utilisation prolongée de l’appareil de robinetterie dans des conditions de fonctionnement spécifiques ou après une usure/agression chimique des matériaux.
NOTE 2        Concernant l’agression chimique des matériaux, un ensemble de données est disponible dans l’ISO/TR 10358 concernant l’essai d’endurance nécessaire pour confirmer l’aptitude des robinets en matériaux thermoplastiques manœuvrés à la main à supporter une utilisation prolongée, avec des manœuvres d’ouverture et de fermeture répétées. Des informations complémentaires sont données dans l’ISO 8659.

Plastomerni ventili - Vrtilni moment - Preskusna metoda (ISO 8233:2024)

Ta dokument določa preskusno metodo za ugotavljanje odpiralnega, zapiralnega in vrtilnega momenta plastomernih ventilov. Preskus spada v sklop začetnega tipskega preskušanja.
Ta dokument se uporablja za vse vrste plastomernih ventilov, predvidenih za uporabo pri prevozu tekočin.
OPOMBA 1: Primeri vrst ventilov, preskušenih s to metodo, so navedeni v standardih ISO 16135, ISO 16136, ISO 16138, ISO 16139, ISO 21787, ISO 4437-4, ISO 16486-4, EN 12201-4, EN 1555-4.
Dokument ne določa razmerja med vrtilnim momentom in njegovim morebitnim povečanjem po daljši uporabi ventila pod določenim obratovalnim pogojem ali ob obrabi/agresivnem kemičnem delovanju materialov.
OPOMBA 2: V zvezi z agresivnim kemičnim delovanjem materialov je v standardu ISO/TR 10358 navedena zbirka podatkov; v zvezi s preskusom vzdržljivosti, ki je potreben za potrditev sposobnosti ročno reguliranih plastičnih ventilov, da vzdržijo daljšo uporabo ob večkratnem odpiranju in zapiranju, so dodatne informacije podane v standardu ISO 8659.
