Office Chair Accessories Testing
Office chair accessories testing covers multiple core components and corresponding items, requiring comprehensive evaluation through specialized equipment simulating real-world working conditions. The specific testing contents are as follows:
Five-star Base Testing
As the core load-bearing base of an office chair, the five-star base requires focused testing on its compressive strength, structural stability, eccentric load-bearing performance, and long-term resistance to deformation. The testing equipment is an office chair five-star base tester, which accurately screens for process defects in five-star bases made of materials such as metal, nylon, and fiberglass by simulating real-world load-bearing conditions (e.g., eccentric loads at different angles), ensuring they can withstand complex stresses during dynamic use.
Rotating Base and Chassis Testing
The chassis and rotating bearings must handle high-frequency rotation, direction changes, and twisting actions. Testing items include load-bearing rotation lifespan, wear resistance, and structural fit accuracy. Using an office chair rotating base lifespan tester, through alternating forward and reverse rotation cycles (e.g., dozens of rotations per minute), long-term office scenarios are simulated to verify the durability and stability of the chassis under continuous friction and stress, preventing issues such as abnormal noises or jamming caused by wear.
Seat Assembly Testing
Seat testing is divided into two main areas: overall durability and foam material:
- Overall Durability: An office chair seat repeated impact tester is used to simulate tens of thousands of sitting impact conditions, testing the seat's resistance to impact, collapse, and structural durability.
- Foam Material: The softness, indentation strength, and compression set of the seat cushion foam are measured using a computerized foam indentation hardness tester; the recovery speed and่ดด่บซ (body-conforming) recovery performance of slow-rebound memory foam are assessed using a foam slow-rebound recovery time tester, ensuring a balance between comfort and support.
Armrest Testing
As a frequently stressed component, armrests require reciprocating fatigue testing (e.g., cyclic loading of lifting, tilting, or fixed structures) using an office chair armrest fatigue tester to verify the durability strength and structural stability of the armrest brackets, hardware connections, and plastic housings, preventing looseness or breakage after long-term use.
Backrest and Recline Mechanism Testing
The chair back and recline mechanism must withstand the tensile loads from human leaning back and rebounding. The testing equipment is an office chair backrest fatigue tester. By simulating high-frequency leaning back-reset cycles (e.g., dozens of leaning back actions per minute), the tensile resistance and deformation resistance of the backrest frame, connecting hardware, and recline structure are tested to ensure stable support for dynamic leaning by the human body.
Chair and Stool Mechanical Performance Testing Items
Also include seat static load, backrest static load, armrest loading, leg loading, seat impact, backrest impact, and seat reciprocating durability tests, comprehensively covering the mechanical performance requirements of office chairs during static and dynamic use.
