Building hardware - Padlocks and padlock fittings - Requirements and test methods

This European Standard applies to mechanical padlocks and padlock fittings used on buildings and general use and specifies the test methods to be used.
This European Standard specifies performance and other requirements for strength, security, durability, performance, and corrosion resistance of padlocks. It establishes one category of use, two categories of durability, six categories for corrosion resistance and six grades for security based on performance tests that simulate attack.
Limited manual attack testing is included in this European Standard because the machine testing does not replicate all known manual attacks.

Baubeschläge - Hangschlösser und Hangschlossbeschläge - Anforderungen und Prüfverfahren

Diese Europäische Norm gilt für mechanische Hangschlösser und Hangschlossbeschläge zur Verwendung in Gebäuden und für den allgemeinen Gebrauch und legt die anzuwendenden Prüfverfahren fest.
Diese Europäische Norm legt Anforderungen an die Leistungsfähigkeit und weitere Anforderungen an Festigkeit, Sicherheit, Dauerhaftigkeit, Leistung und Korrosionsbeständigkeit von Hangschlössern fest. Sie legt eine Gebrauchsklasse, zwei Klassen für die Dauerhaftigkeit, sechs Klassen für die Korrosionsbeständigkeit und sechs Klassen für die Sicherheit fest. Letztere basieren auf Leistungsprüfungen, in denen Angriffe simuliert werden.
In dieser Europäischen Norm ist eine begrenzte manuelle Angriffsprüfung enthalten, da die maschinelle Prüfung nicht alle bekannten Möglichkeiten eines manuellen Angriffs nachbildet.

Quincaillerie pour le bâtiment - Cadenas et porte-cadenas - Exigences et méthodes d'essai

La présente Norme européenne s’applique aux cadenas mécaniques et aux porte-cadenas utilisés dans le bâtiment et pour une utilisation générale et il spécifie les méthodes d’essai à utiliser.
La présente Norme européenne spécifie les performances et autres exigences relatives à la résistance, à la sécurité des biens, l’endurance, au fonctionnement et à la résistance à la corrosion des cadenas. Il définit une catégorie d’utilisation, deux catégories d’endurance, six catégories pour la résistance à la corrosion et six grades pour la sécurité des biens.
Des essais limités d'attaque manuelle sont inclus dans la présente Norme européenne du fait que la machine d’essai ne reproduit pas toutes les attaques manuelles connues.

Stavbno okovje - Obešanke in dodatki za obešanke - Zahteve in preskusne metode

Ta evropski standard obravnava mehanske obešanke in dodatke za obešanke za uporabo na stavbah in splošno uporabo ter določa preskusne metode, ki bodo uporabljene. Ta evropski standard določa lastnosti in druge zahteve glede trdnosti, varnosti, trajnosti, delovanja in odpornosti obešank na korozijo. Določa eno kategorijo uporabe, dve kategoriji trajnosti, šest kategorij odpornosti na korozijo in šest varnostnih stopenj na podlagi preskusov delovanja s simulacijo napada. V evropski standard je vključeno omejeno ročno preskušanje napada, ker strojno preskušanje ne ponovi vseh znanih ročnih napadov.

5.1 General 5.1.1 Introduction The manufacturer will provide assembly and component drawings to enable the tester to carry out a preliminary product assessment prior to testing. The padlock shall be tested in the locked position with the key removed.
It is not necessary for the correct key to operate the padlock after testing. Padlocks/ padlock fittings and their original keys shall be taken at random and submitted for each test.
In the event of one of the original two samples failing the test, the padlocks/ padlock fittings shall be deemed to have failed and a further two shall be tested, both of which shall pass the test.
