Scope

Main Technical Specifications: 6. Technical Requirements 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 visible bubbles, flaking, or exposed base metal. 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 a uniform color and no obvious scratches, bubbles, or peeling. 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 on the coated surface should be ≤5%. 6.1.3.3 Not less than the requirements of 2H in GB/T 6739. 6.1.4 Color Difference The product’s electroplated or coated surface should meet the design requirements, with defective areas ≤15% of the tested area. The maximum difference between the darkest and lightest shades should not exceed one color code. 6.2 Permissible Tolerances 6.2.1 Lock Body Length The length of the lock body should be within ±3 mm of the specified value. 6.2.2 Lock Body Width The width of the lock body should be within ±2 mm of the specified value. 6.3 Flexibility 6.3.1 Mechanical Key Opening 6.3.1.1 The mechanical key opening of the luggage lock should be smooth, with a key opening torque of M1≤1 N·m and the lock successfully opening. 6.3.1.2 The buttons or password wheels of the combination lock should position accurately. At the set code position, the button should slide the latch smoothly without any jams. There should be no code errors, lock failures, or stuck mechanisms. 6.3.2 Rotating the lock cylinder with a mechanical key should be smooth, with a smooth extraction and insertion of the lock cylinder. The key insertion and removal force F1 should be ≤12 N. 6.3.3 Locking and releasing the latch should be smooth, with a downward pressing force F2≤20 N.
