Industrial valves - Design validation-testing of valves (ISO 23632:2021)

Le présent document spécifie les exigences et les critères d’acceptation pour les essais de type, conformes aux conditions de conception, des robinets à tournant sphérique métalliques et robinets à papillon métalliques utilisés pour des services de sectionnement pour toutes les applications industrielles, et sert à valider la conception des produits sur 205 cycles.
Le présent document exclut les essais de dispositifs de sécurité, de robinets de régulation, de robinets en matériaux thermoplastiques, et des robinets pour l’alimentation en eau destinée à la consommation humaine et en eaux usées (par exemple la série EN 1074).
Le présent document définit la procédure permettant d’étendre la qualification de l’appareil de robinetterie soumis à l’essai à des désignations de dimensions et de pression non soumises à l’essai de la même gamme de produits.
Cet essai de type a pour objet de valider la performance de siège pour la relation pression/température précisée par le fabricant, qui figure dans la documentation technique du produit donnée par le fabricant. Cet essai de type vérifie les exigences de couple et le couple de manœuvre maximale admissible (MAST), tels que donnés dans la documentation technique du fabricant. Cet essai de type valide la durabilité de la performance de siège et le couple de manœuvre grâce à des cycles mécaniques et thermiques.

Industriearmaturen - Validierungsprüfung der Konstruktion von Armaturen (ISO 23632:2021)

Dieses Dokument legt Anforderungen und Abnahmekriterien für die Typprüfung von metallischen Klappen und Kugelventilen für die Isolierung von Versorgungsleitungen für alle industriellen Anwendungen in Übereinstimmung mit den Gestaltungsbedingungen fest und dient der Validierung der Produktgestaltung über 205 Zyklen.
Dieses Dokument schließt Prüfungen von Sicherheitseinrichtungen, Regelarmaturen, thermoplastischen Armaturen sowie Trinkwasser- und Abwasserarmaturen (z. B. die Normenreihe EN 1074) aus.
Dieses Dokument legt Verfahren für die Erweiterung der Qualifikation der geprüften Armatur auf ungeprüfte Größen und Druckangaben desselben Produktbereichs fest.
Diese Typprüfung dient dazu, die Leistung des Sitzes innerhalb des von dem Hersteller angegebenen Druck-/ Temperaturbemessungsbereichs wie in der technischen Produktdokumentation des Herstellers angegeben zu validieren. Diese Typprüfung verifiziert die Momentanforderungen und das maximal zulässige Drehmoment der Schaftwelle (MAST) wie in der technischen Dokumentation des Herstellers angegeben. Diese Typprüfung validiert die Dauerhaftigkeit der Sitzleistung und des Betätigungsmoments durch mechanische und thermische Zyklen.

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).

Introduction
The scope of this document is currently limited to ball and butterfly valves.
The objective of this document is to outline the requirements and methods for evaluating the
performance of metallic industrial valves with respect to seat performance and operating torque
capability. Fugitive emission performance was omitted, as it is covered by ISO 15848-1. The number
of cycles (205) is consistent with the number in C01 of ISO 15848-1:2015. It serves to test the accuracy
and dependability of the measurements and capabilities of a valve as published by the manufacturer in
the valve’s technical documentation.
Type validation is the most reliable method to validate a range of valve products, covering many
aspects, such as its design, material selection and manufacturing processes. It will also serve as a guide
for valve selection, allowing customers to compare different valve types, designs and brands.
Several major customers already require type tests, each having their own requirements and
specifications. Introducing a defined International Standard will reduce manufacturer's costs by
decreasing the number of qualifications, as well as decreasing end-user total cost-of-ownership, by
eliminating the possibility of unintentional design flaws.
This validation will improve performance and safety in the plants by enabling any customer to specify
durable type-tested industrial valves.
