Testing of valves - Fire type-testing requirements (ISO 10497:2022)

This document specifies fire type-testing requirements and a fire type-test method for soft- and metal-seated isolation valves with one or more obturators. It is not applicable to the testing requirements for valve actuators other than manually operated gearboxes or similar mechanisms when these form part of the normal valve assembly. Other types of valve actuators (e.g. electrical, pneumatic or hydraulic) can need special protection to operate in the environment considered in this valve test, and the fire testing of such actuators is outside the scope of this document.
This document specifies the measurement and assessment criteria for:
a) through-seat leakage;
b) external leakage;
c) cavity overpressure relief of double-seated valves;
d) operability.
This document specifies the rules whereby the fire-type testing qualification for a valve can be extended to untested sizes, pressure ratings and materials of construction of the same basic design type.
Fire test reports of valves tested according to previous editions of this document are acceptable when submitted together with the full and compliant fire test report as per 6.7 of the edition under which it was tested. Any data missing as required from 6.7 within the fire test report are accepted or rejected at the purchaser’s discretion.
NOTE       For the purposes of this document, the terms “fire type-test” and “fire test” are synonymous.

Prüfung von Armaturen - Anforderungen an die Typprüfung auf Feuersicherheit (ISO 10497:2022)

Dieses Dokument legt Anforderungen an die Typprüfung auf Feuersicherheit und das zugehörige Verfahren für Absperrarmaturen mit Weich- oder Metallsitzen mit einem oder mehreren Abschlusskörpern fest. Es enthält keine Prüfanforderungen an Stellantriebe, ausgenommen handbetätigte Schaltgetriebe oder ähnliche Mechanismen, wenn diese Teile der Standardausführung sind. Andere Stellantriebe (z. B. elektrische, pneumatische oder hydraulische) müssen eventuell für diese Armaturenprüfung mit einem besonderen Schutz versehen werden und die Prüfung der Feuersicherheit solcher Antriebe liegt nicht im Anwendungsbereich dieses Dokuments.
Dieses Dokument legt die Mess- und Beurteilungskriterien für Folgende fest:
a)   Undichtheit des Sitzes;
b)   äußere Undichtheit;
c)   Überdruckentlastung im Gehäuseinnenraum von Doppelsitzventilen;
d)   Bedienbarkeit.
Dieses Dokument legt die Regeln fest, nach denen der Eignungsnachweis aus der Typprüfung auf Feuersicherheit eines Ventils auf ungeprüfte Nennweiten, Druckstufen und Werkstoffe der gleichen Grundbauart erweitert werden kann.
Prüfberichte zu Prüfungen auf Feuersicherheit von nach vorherigen Ausgaben dieses Dokuments geprüften Armaturen sind annehmbar, wenn sie zusammen mit dem vollständigen und konformen Prüfbericht zur Prüfung auf Feuersicherheit nach 6.7 dieser Ausgabe eingereicht werden, nach dem sie geprüft wurden. Jegliche im Prüfbericht zur Prüfung auf Feuersicherheit fehlenden Daten, die nach 6.7 erforderlich sind, werden nach Anforderung des Kunden angenommen oder abgelehnt.
ANMERKUNG   Für die Anwendung dieses Dokuments sind die Begriffe „Typprüfung auf Feuersicherheit“ und „Feuersicherheitsprüfung“ gleichbedeutend.

Essais des appareils de robinetterie - Exigences de l'essai au feu (ISO 10497:2022)

Le présent document spécifie les exigences d'un essai type au feu et une méthode d'essai type au feu pour les robinets d'isolation à siège souple et métallique avec un obturateur ou plus. Il ne traite pas des conditions d'essai des actionneurs des appareils de robinetterie autres que des réducteurs manuels ou autres mécanismes du même type liés à l'appareil normalement assemblé. D'autres types d'actionneurs (par exemple électriques, pneumatiques ou hydrauliques) peuvent, compte tenu des conditions du présent essai, nécessiter des protections particulières, et leur contrôle sort du cadre du présent document.
Le présent document spécifie les critères de mesurage et d’évaluation pour:
a) les fuites à travers le siège;
b) les fuites externes;
c) l’évacuation de la surpression dans la cavité des appareils de robinetterie à double siège;
d) la manœuvrabilité.
Le présent document spécifie les règles pour étendre la qualification de l’essai de type au feu d’un appareil de robinetterie de même conception de base, à des dimensions, des pressions et des matériaux de construction non soumis à essai.
Les rapports d’essai au feu d’appareils de robinetterie soumis à essai selon les éditions précédentes du présent document sont acceptables quand ils sont soumis avec un rapport d’essai au feu complet et conforme au 6.7 de l’édition selon laquelle il a été soumis à essai. Toutes données manquantes telles que requises en 6.7 dans le rapport d’essai au feu sont acceptées ou rejetées sur décision de l'acheteur.
NOTE          Pour les besoins du présent document, les termes “essai de type au feu” et “essai au feu” sont synonymes.

Preskušanje ventilov - Zahteve za protipožarno preskušanje (ISO 10497:2022)

Ta dokument določa zahteve za protipožarno preskušanje in protipožarno metodo za mehke in kovinske zaporne ventile z enim ali več čepi. Ne uporablja se za zahteve glede preskušanja sprožil ventilov, razen ročnih menjalnikov ali podobnih mehanizmov, če so ti del običajnega sklopa ventilov. Za druge vrste sprožil ventilov (npr. električnih, pnevmatskih ali hidravličnih) je morda potrebna posebna zaščita, če delujejo v okolju, obravnavanem v tem preskusu ventilov, požarno preskušanje takih sprožil pa je zunaj področja uporabe tega dokumenta. Ta dokument določa merila, s katerimi se meri in ocenjuje: a) puščanje skozi sedež ventila; b) zunanje puščanje; c) razbremenitev nadtlaka v votlini dvosedežnih ventilov; d) operativnost. Ta dokument določa pravila, po katerih se lahko razvrstitev protipožarnega preskusa za ventil razširi na nepreizkušene velikosti, nazivne tlake in materiale konstrukcije iste osnovne zasnove. Poročila o požarnem preskusu ventilov, preskušenih v skladu s prejšnjimi izdajami tega dokumenta, so sprejemljiva, če so predložena skupaj s popolnim in skladnim poročilom o požarnem preskusu v skladu s točko 6.7 izdaje, na podlagi katere je bil opravljen preskus. Kupec po lastni presoji sprejme ali zavrne morebitne manjkajoče podatke v skladu s točko 6.7 v poročilu o požarnem preskusu. OPOMBA: Za namene tega dokumenta sta izraza »protipožarni preskus« in »požarni preskus« enakovredna.

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.
