Building hardware - Cylinders and Master-Key-Systems (MKS) for locks - Requirements and test methods

Edition date: 2026-05-13
In Force
Available languages: French, English
Summary: This document applies to cylinders and their keys for such locks as are normally used in buildings and are designed to be used with cylinders, where the locks have an operational torque of maximum 1,5 Nm. This document specifies performance and other requirements for the strength, security, durability, performance and corrosion resistance of cylinders and their original keys. It also specifies cylinders suitable for use in locking systems, Master key systems (MKS). It establishes one category of use, three grades of durability, two grades for mechanical coding (single cylinders and MKS), three grades for fire and four grades corrosion resistance all based on performance tests as well as six grades of key related security based on design requirements and five grades on performance tests that simulate attack. This document includes tests of satisfactory operation at a range of temperatures. It specifies test methods to be used on cylinders and their protective measures linked with these cylinders and recommended by the manufacturer. Corrosion resistance is specified by reference to the requirements of EN 1670 on corrosion resistance of building hardware. The suitability of cylinders for use on fire or smoke-door assemblies is determined by fire performance tests conducted in addition to the performance testing required by this document, see Annex A. This document does not apply to the assessment of fire resistance and smoke control doors equipped with lock cylinders grade A and grade B.

Le présent document s’applique aux cylindres et à leurs clés destinés aux serrures qui sont normalement utilisées dans le bâtiment et conçues pour fonctionner avec des cylindres, avec un couple de manœuvre maximal de 1,5 Nm. Le présent document spécifie la performance et d’autres exigences relatives à la résistance, à la sécurité des biens, à l’endurance, à la performance et à la résistance à la corrosion des cylindres et de leurs clés d’origine. Il spécifie également les cylindres pour une utilisation dans les systèmes de verrouillage, les Systèmes d’organigrammes de clé (système MK). Il établit une catégorie d’utilisation, trois grades d’endurance, deux grades de codage mécanique (cylindres individuels et système MK), trois grades de résistance au feu et quatre grades de résistance à la corrosion, tous basés sur des essais de performance, six grades de sécurité des biens relative à la clé, fondés sur des exigences de conception, et cinq grades fondés sur des essais de performance simulant une attaque. Le présent document comprend des essais de bon fonctionnement dans une certaine plage de températures. Il spécifie les méthodes d’essai pour les cylindres ainsi que les dispositifs de protection correspondants à ces cylindres et recommandés par le fabricant. La résistance à la corrosion est spécifiée par référence aux exigences de l’EN 1670 relatives à la résistance à la corrosion de la quincaillerie pour le bâtiment. L’aptitude à l’utilisation des cylindres sur des blocs-portes coupe-feu ou pare-fumées est déterminée par des essais de performance au feu, qui s’ajoutent aux essais de performance requis dans le présent document, voir Annexe A. Le présent document ne s’applique pas à l’’évaluation de la résistance au feu et de l'étanchéité aux fumées des portes équipées de cylindres de serrure de grade A et grade B.

Dieses Dokument ist anwendbar für Schließzylinder und ihre Schlüssel für solche Schlösser, die üblicherweise in Gebäuden verwendet werden und die für die Verwendung mit Schließzylindern vorgerichtet sind, wobei die Schlösser ein Betätigungsmoment von höchstens 1,5 Nm aufweisen. Dieses Dokument enthält Festlegungen für die Leistungsfähigkeit sowie weitere Anforderungen an Festigkeit, Verschlusssicherheit, Dauerhaftigkeit, Leistung und Korrosionsbeständigkeit von Schließzylindern und ihren Originalschlüsseln. Es legt auch die Schließzylinder fest, die für die Verwendung in Schließanlagen, Hauptschlüsselanlagen (HS-Anlage), geeignet sind. Sie legt eine Gebrauchsklasse fest, drei Klassen für Dauerhaftigkeit, zwei Klassen für die mechanische Codierung (Einzelzylinder und HS-Anlagen), drei Klassen für Feuerwiderstand und vier Klassen für Korrosionsbeständigkeit, jeweils unter Zugrundelegung von Leistungsprüfungen, außerdem sechs Klassen für Verschlusssicherheit unter Zugrundelegung von Konstruktionsanforderungen und fünf Klassen von Leistungsprüfungen, die mechanischen Angriff simulieren. Dieses Dokument beinhaltet Prüfungen über die einwandfreie Funktionsfähigkeit bei verschiedenen Temperaturen. Sie legt Prüfverfahren für Schließzylinder sowie damit verbundene und vom Hersteller empfohlene Schutzeinrichtungen fest. Die Korrosionsbeständigkeit wird durch Verweisung auf die Anforderungen von EN 1670 über die Korrosionsbeständigkeit von Schlössern und Baubeschlägen festgelegt. Die Eignung von Schließzylindern für die Verwendung in Feuer- oder Rauchschutztüren wird durch die Prüfung der Feuerwiderstandsfähigkeit bestimmt, die zusätzlich zu den Leistungsprüfungen nach diesem Dokument gefordert wird, siehe Anhang A. Dieses Dokument ist nicht anwendbar für die Beurteilung von Feuerschutz- und Rauchschutztüren selbst, die mit Schließzylindern der Klasse A und der Klasse B ausgestattet sind.
