20、uropean 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.

21、 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 a

22、ll known manual attacks. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

The padlock shall be tested in the loc

48、ked 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.
