Scope

Main Technical Content: 5.1 Flexibility of Locking Operation The padlock should be easy to unlock. The key unlocking torque M1 should not exceed 1 N·m, and the lock beam should be able to open. For combination locks, the buttons or number wheels should be accurately positioned. At the set coding position, the lock beam should open and close without any resistance. Key insertion and extraction force: The key insertion and extraction force should not exceed 10 N. Lock beam compression closing force: The lock beam compression closing force should not exceed 70 N. 5.2 Strength According to Test 6.3.1, the lock beam should withstand the tensile force specified in Table 1 without the lock being opened. According to Test 6.3.2, the lock beam should withstand the torsional moment M specified in Table 1 without the lock being opened. According to Test 6.3.3, the lock beam should resist shearing forces of F specified in Table 1 and not be cut off. According to Test 6.3.4, the padlock should withstand the impact force specified in Table 1 without opening. According to Test 6.3.5, the lock cylinder pins and locking mechanisms should withstand the tensile force specified in Table 1 without separating from the lock body. According to Test 6.3.6, the padlock's lock beam should withstand the anti-sawing time specified in Table 1 and not be cut off. According to Test 6.3.7, after a specified number of impacts, the lock should not open. After dropping from a height of 1.8 m, the lock should still function normally without any cracking in the lock beam or lock body. 5.3 Security For pin and leaf locks, the number of key teeth should comply with Table 1. For pin and leaf locks, the key interchangeability rate should comply with Table 1. For combination locks, the number of codes should be no less than 900. Except for the set code, the combination lock should not be able to be opened. For pin-structured padlocks, the anti-picking safety device s
