Industrial valves - Minimum performance requirements

This European Standard defines the minimum performance requirements which apply to industrial valves. It specifies test procedures and acceptance criteria for each performance requirement of this European standard.
Valves for specific use, where such a performance requirements already exists are excluded from this standard:
a)   valves to be used in water supply pipe system in accordance with EN 1074 (all parts);
b)   valves to be used in gas distribution system with pressure lower than 16 bar in accordance with EN 13774;
c)   control valves in accordance with EN 1349;
d)   safety devices in accordance with EN ISO 4126 (all parts).

Industriearmaturen - Mindestleistungsanforderungen

Diese Europäische Norm legt die Mindestleistungsanforderungen fest, die für Industriearmaturen gelten. Sie bestimmen Prüfverfahren und Abnahmekriterien für jede Leistungsanforderung dieser Europäischen Norm.
Armaturen zur besonderen Verwendung, für die eine solche Leistungsanforderung bereits vorhanden ist, sind von dieser Norm ausgeschlossen:
a)   Armaturen in Wasserversorgungsrohrleitsystemen in Übereinstimmung mit EN 1074 (alle Teile);
b)   Armaturen in Gasverteilungssystemen mit einem Druck von weniger als 16 bar in Übereinstimmung mit EN 13774;
c)   Regelarmaturen in Übereinstimmung mit EN 1349;
d)   Sicherheitseinrichtungen in Übereinstimmung mit EN ISO 4126 (alle Teile).

Robinetterie industrielle - Exigences minimales de performance

La présente Norme Européenne définit les exigences de performances minimales qui s'appliquent aux appareils de robinetterie industrielle. Elle spécifie les procédures d'essai et les critères d'acceptation de chaque exigence de performance de la présente Norme Européenne.
Les appareils de robinetterie pour des utilisations spécifiques, pour lesquels de telles exigences de performance existent déjà, sont exclus de la présente norme:
a)   appareils de robinetterie à utiliser dans des réseaux d'alimentation en eau conformément à l'EN 1074 (toutes les parties);
b)   appareils de robinetterie à utiliser dans les systèmes de distribution du gaz avec une pression inférieure à 16 bar conformément à l'EN 13774;
c)   robinets de régulation conformément à l'EN 1349;
d)   dispositifs de sécurité conformément à l'EN ISO 4126 (toutes les parties).

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 69.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and
