4.6.3.1 Forced entry test. The padlock shall withstand a concentrated forced
entry for a minimum of 1 minute, using a 3-lb (1.36 kg) hammer with an 18-inch
(457 mm) handle. If the padlock opens, it shall constitute a failure.
4.6.3.2 Key integrity test. The test padlock shall be a locked padlock. The
keys from 10 other padlocks selected at random from all the padlocks in the sample
shall be used to attempt to unlock the test padlock. A key from each of the 10
padlocks shall be fully inserted into the keyway. The key shall then be slowly
withdrawn while applying a jiggling-twisting force in the direction that the lock
normally opens. The padlock shall resist the withdrawing and jiggling-twisting
force for a minimum of 1 minute with each key without opening. If the test padlock
opens, it shall constitute a failure.
4.6.3.3 Cylinder interchangeability test. Remove the cylinder assemblies from
the test padlocks and insert each of them into different padlocks. Operate each
padlock through not less than five cycles. If the padlocks fail to lock and unlock
using each of the replacement cylinder/key assemblies, it shall constitute a
failure. A cycle consists of the following:
a. Fully insert the key into the keyway.
b. Rotate the key and cylinder plug the necessary number of degrees to open
the padlock.
c. Pull the shackle fully open.
d. Reengage the shackle to the locked position.
e. Return the key and cylinder plug to the locked position.
