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
Dieses Dokument gilt für mechanische Hangschlösser und Hangschlossbeschläge zur üblichen Verwendung in Gebäuden und legt die anzuwendenden Prüfverfahren fest.
Dieses Dokument legt Anforderungen an die Leistungsfähigkeit sowie weitere Anforderungen an Festigkeit, Sicherheit, Dauerhaftigkeit, Leistung und Korrosionsbeständigkeit von Hangschlössern fest. Es legt eine Gebrauchsklasse, zwei Klassen für die Dauerhaftigkeit, sechs Klassen für die Korrosionsbeständigkeit und sechs Klassen für die Sicherheit fest.
In dieser Norm ist eine begrenzte manuelle Angriffsprüfung enthalten, da die maschinelle Prüfung nicht alle bekannten Möglichkeiten eines manuellen Angriffs nachbildet.
Die auf die Sicherheit bezogenen Anforderungen sind auf der Grundlage von Leistungsprüfungen, in denen Angriffe simuliert werden, in sechs Klassen eingeteilt.
Quincaillerie pour le bâtiment - Cadenas et porte-cadenas - Exigences et méthodes d'essai
Le présent document s’applique aux cadenas mécaniques et aux porte-cadenas normalement utilisés dans le bâtiment et il spécifie les méthodes d’essai à utiliser.
Le présent document 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.
L'essai d'attaque manuelle limitée est inclus dans la présente norme du fait que la machine d’essai ne reproduit pas toutes les attaques manuelles connues.
Les exigences relatives à la sécurité des biens sont classées suivant six grades, en fonction des résultats aux essais simulant une attaque.
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.
SIST EN 12320:2013
EN 12320:2012 (E) 9 If the parts to be tested are inaccessible when the product is correctly mounted in accordance with the manufacturer's instructions, the product shall be considered to have passed that test.
A padlock shall be deemed to have been opened when a bar, of equal cross-section to that of its shackle, can be released. Ability to open can be checked at any time during the test by manipulation with a screwdriver or similar implement (maximum length 200 mm) for a period of 5 s max.
5.1.2 Tolerances Unless otherwise stated, the following tolerances shall apply :
force ± 2 % ;
torque ± 2 % ;
mass/weight ± 2 % ;
distance ± 2 % ;
time ± 5 s ;
temperature ± 2 °C.
Unless otherwise stated, the forces shall be applied progressively and without shock to the required load within 1 min.
5.1.3 Test environment The ambient temperature of the test environment shall be controlled throughout the test to 20 °C ± 5 °C unless otherwise stated.
5.1.4 Test tools
Specification of steel for cutting and impact tests as required in 5.5.7.1 and 5.5.8. shall be structural steel E335 defined in EN 10025-2, heat treated to have a hardness of 60 HRC to 64 HRC. 5.1.5 Sampling
Test sampling and sequencing shall be in accordance with Annex A.
5.2 Category of use
5.2.1 Operational unlocking test.
Mount the padlock in a suitable holding fixture, and apply a torque to a fully inserted correct key using a torque-meter, as shown in Figure B.1. At no point between locked and unlocked shall the torque exceed 1 Nm.
5.2.2 Key strength Requirements for key strength shall meet the requirements given in 5.2 of EN 1303:2005. SIST EN 12320:2013
EN 12320:2012 (E) 10 5.3 Durability The durability test shall be carried out using suitable apparatus that allows the full operational locking and unlocking sequence of the padlock to include the release of the shackle. (It is not necessary for the shackle to be turned). Repeat the sequence at a speed of 5 to 20 cycles per minute
During the operational cycle the key may remain partially inserted in the locking mechanism but shall have cleared all movable detainers. The key used for the durability test can be cleaned and the padlock shall be lubricated in accordance with the manufacturer’s instructions at the start of the test and after each 5000 cycles using the lubricant recommended by the manufacturer. After completing the required number of cycles the operation of the padlock shall be tested using a new original key. The rotation shall be achieved with a maximum torque of 1.5 Nm. If the padlock should jam and cease to operate during the test, then provided the padlock continues to operate in the proper manner when released, the test shall be allowed to continue. No durability requirements for padlock fittings. 5.4 Corrosion resistance
5.4.1 Preparation The padlock is locked on a staple which is mounted on a wooden block and placed in the chamber for salt spray test. The padlock without a key is oriented in the manner that it would assume to be in use. The padlock shall be exposed to a neutral salt spray test in accordance with EN 1670. Grade 0:
no defined corrosion resistance; Grade 1:
24h +1h/-0 h; Grade 2:
48h +1h/-0 h; Grade 3:
96h +1h/-0 h;
Grade 4:
240h +1h/-0 h; Grade 5: 480h +1h/-0 h. 5.4.2 Test of padlock function after salt spray exposure The evaluation shall be made in accordance with EN 167
