| Technical Parameters: 1. Seat and Backrest Combined Durability Test: A force of 950N is applied to the seat surface, followed by a force of 330N applied to the back, for a total of 200,000,000 cycles, at a frequency not exceeding 40 cycles. 2. Seat Impact Test: A 102kg/136kg sandbag impacts the seat surface once from a height of 152mm. Chairs with lift functions will also be tested once more. 3. Seat Durability Test: A 57kg sandbag impacts the seat surface 1,000,000 times from a height of 25cm, followed by a front-facing angle test. 4. Backrest Static Strength Test: A force of 890N/1334N/667N/1112N is applied to the seat back and maintained at a 1mm interval. 5. Backrest Kinetic Durability Test: A 102kg mass is placed on the seat surface, and a force of 445N/334N is repeatedly applied to the back. The test is repeated 1,200,000 times for back widths ≤406mm and 80,000 times for back widths >406mm. This force is then repeated 20,000 times on each side of the seat back. 6. Seat Alternating Bending Durability Test: A 203mm diameter load block is used to slowly and alternately apply a force of 734N to the front corners of the seat at a rate of 10-30 cycles, for a total of 200,000 cycles. 7.
