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.

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
