Testing of valves - Fire type-testing requirements (ISO 10497:2010)
ISO 10497:2010 specifies fire type-testing requirements and a fire type-test method for confirming the pressure-containing capability of a valve under pressure during and after the fire test. It is not applicable to the testing requirements for valve actuators other than manually operated gear boxes 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 ISO 10497:2010.
Prüfung von Armaturen - Anforderungen an die Typprüfung auf Feuersicherheit (ISO 10497:2010)
Diese Internationale Norm legt Anforderungen an die Typprüfung auf Feuersicherheit und das zugehörige
Verfahren zum Nachweis der Druckfestigkeit einer Armatur fest, die während und nach der Feuersicherheitsprüfung
mit Druck beaufschlagt wird. Sie 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 dieser Norm.
Bescheinigungen über die Prüfung auf Feuersicherheit von Armaturen, die nach früheren Ausgaben der
ISO 10497 und ähnlichen, international anerkannten Feuersicherheitsprüfnormen geprüft wurden, sind ebenfalls
annehmbar.
ANMERKUNG Für die Anwendung dieser Internationalen Norm sind die Begriffe „Typprüfung auf Feuersicherheit“ und
„Feuersicherheitsprüfung“ gleichbedeutend.
Essais des appareils de robinetterie - Exigences de l'essai au feu (ISO 10497:2010)
L'ISO 10497:2010 spécifie les exigences d'un essai type au feu et une méthode d'essai type au feu permettant d'établir la capacité de tenue en pression d'un appareil de robinetterie sous pression pendant et après l'exécution de l'essai au feu. Elle 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 de l'ISO 10497:2010.
Preskušanje ventilov - Zahteve za protipožarno preskušanje (ISO 10497:2010)
Ta mednarodni standard določa zahteve za protipožarno preskušanje in metodo za protipožarno preskušanje za potrditev tlačne zmogljivosti ventila pod tlakom med protipožarnim preskušanjem in po njem. Ne velja za preskusne zahteve za pogone za ventile, ki niso ročno upravljani menjalniki ali podobni mehanizmi, kadar so ti del normalnega sestava ventilov. Druge vrste pogonov za ventile (npr. električni, pnevmatični ali hidravlični) lahko potrebujejo posebno zaščito za delovanje v okolju, obravnavanem pri tem preskusu ventilov, in protipožarno preskušanje takih pogonov je zunaj obsega uporabe tega mednarodnega standarda. Sprejemljivi so tudi certifikati protipožarnega preskušanja ventilov, ki so bili predhodno preskušani v skladu s prejšnjimi izdajami ISO 10497 in podobnimi mednarodno priznanimi standardi protipožarnega preskušanja.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 10497 was prepared by Technical Committee ISO/TC 153, Valves, Subcommittee SC 1, Design,
manufacture, marking and testing.
This third edition cancels and replaces the second edition (ISO 10497:2004), which has been technically
revised.

ISO 10497:2010(E)
Introduction
This International Standard covers the requirements and method for evaluating the performance of valves
when they are exposed to defined fire conditions. The performance requirements establish limits of
acceptability of a valve, regardless of size or pressure rating. The burn period has been established to
represent the maximum time required to extinguish most fires. Fires of longer duration are considered to be of
major magnitude, with consequences greater than those anticipated in the test.
The test pressure during the burn is set at 0,2 MPa (2 bar) for soft-seated valves rated PN 10, PN 16, PN 25
and PN 40, Class 150 and Class 300, to better simulate the conditions that would be expected in a process
plant when a fire is detected and pumps are shut down. In this case, the source of pressure in the system is
the hydrostatic head resulting from liquid levels in towers and vessels. This situation is approximated by this
lower test pressure.
In production facilities, valves are typically of a higher rating and the pressure source is not easily reduced
when a fire is detected. Therefore, for all other valves, the test pressure during the burn is set at a higher
value to better simulate the expected service conditions in these facilities.
Use of this International Standard assumes that the execution of its provisions is entrusted to appropriately
qualified and experienced personnel, because it calls for procedures that can be injurious to health, if
adequate precautions are not taken. This International Standard refers only to technical suitability and does
not absolve the user from legal obligations relating to health and safety at any stage of the procedure.
