BS EN 12320:2012EN 12320:2012 (E) 4 1 Scope 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 Europe
18、an 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 t
19、ests that simulate attack. Limited manual attack testing is included in this European Standard because the machine testing does not replicate all known manual attacks. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensab

45、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 take
46、n 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. BS EN 12320:2012EN 12320:2012 (E) 9 If the parts to be tested
47、 are inaccessible when the product is correctly mounted in accordance with the manufacturers 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 op
48、en 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 ;
49、 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
