Load Capacity Test
Dynamic Testing: Vehicles undergo testing at speeds of 15, 25, and 35 kilometers per hour for 2 kilometers each on standard adverse road conditions to ensure safety. Load Capacity: 330 pounds Test Load: 440 pounds
Tensile Test
Condition: For Roof rack crossbar, we apply a static load of 322 lbs (test load) Result:After the static load test, all roof rack crossbars withstand 322 lbs of tension without any signs of deformation (including bending, warping, or structural indentation).
Salt Spray Test
Condition: Roof luggage rack system subjected to continuous spray of 5% saline solution for 192 hours. Result: After continuous spraying of 5% neutral saline solution for 192 hours, no signs of rust, white spots, or corrosion were observed.
Ultraviolet Test
Condition: Products are exposed to simulated solar UV radiation (wavelength 280-400nm) for 1000 hours at 60℃ ambient temperature. Result: No fading, cracking, or material brittleness is observed; surface hardness and structural strength remain unchanged.
Temperature Cycle Test
Condition: 50 cycles of extreme temperature variation (from -40℃ to 80℃), with 2 hours of holding time at each temperature extreme. Result: After 50 cycles, product joints, fasteners, and plastic components show no loosening or damage; functional performance is normal.
Vibration Test
Condition: Roof boxes are tested on a professional machine (ISO 11154 compliant), simulating harsh roads (gravel, potholes) via vibrations matching 15/25/35km/h. Each speed stage lasts for the equivalent of 2km driving; products are mounted on standard roof fixtures. Result: No loose parts, displacement or abnormal noise. The roof box stays firmly attached to the fixture, meeting real-road stability requirements.
Impact Resistance Test
Condition: Controlled impact with 50J energy (equivalent to accidental collision during loading/unloading) on key stress points of products. Result: No cracks, fractures, or functional failure; impact points show only minor indentations that do not affect use.
