Scope

Main Technical Content: 6.1 Surface Quality 6.1.1 Overall Appearance The product's trademarks, lettering, and patterns should be clear and neat. The surface should be smooth, with no obvious scratches. 6.1.2 Electroplated Surface The electroplated surface should not have obvious bubbles, peeling, or exposed metal. The defects should be ≤1 point, and the area should be ≤0.5 mm2. 6.1.3 Coated Surface 6.1.3.1 The coated surface should have uniform color and no obvious scratches, bubbles, or peeling. The defects should be ≤1 point, and the area should be ≤0.5 mm2. 6.1.3.2 After the grid test according to 7.1.3.2, the peeling area of the coated surface should be ≤5%. 6.1.3.3 After the hardness test according to 7.1.3.3, there should be no damage to the coated surface. 6.1.4 Color Difference The products' electroplated and coated surfaces should meet the design requirements. The defect area should be ≤15% of the tested area, and the maximum and minimum color differences should not exceed one shade. 6.2 Flexibility 6.2.1 Mechanical Key Lock Operation 6.2.1.1 The mechanical key lock of the luggage lock should operate smoothly. The key locking torque M1 should be ≤1 N·m, and the lock should be able to open. 6.2.1.2 The buttons or password wheels of the combination lock should position accurately. At the set coding position, the button should push and pull the latch smoothly without any jamming. There should be no code confusion, lock failure, or jamming. 6.2.2 The mechanical key should rotate the lock cylinder smoothly, and the smooth extraction and insertion of the lock cylinder should be ensured. The key insertion and extraction force F1 should be ≤12 N. 6.2.3 The locking and popping of the latch should be smooth, and the downward closing force F2 should be ≤20 N. 6.3 Strength 6.3.1 Tensile Strength of the Latch The tensile strength of the latch F3 should be ≥200 N. 6.3.2 Firmness of the Lock Body Installation The lock body shou
