Cangzhou Office Chair Testing

Office chair testing in Cangzhou can be carried out through professional equipment, testing platforms, and specific testing methods.

Testing Equipment

The office chair impact fatigue testing machine produced by Yuzhan Instrument Equipment (Cangzhou) Co., Ltd. is an important piece of equipment for office chair testing. This device can perform tests on the impact strength of the chair surface of office chairs. The impact speed can be adjusted within the range of 10 - 30 times per minute or specified (m/s). It is a semi-automatic impact testing machine with an applicable scope covering the entire chair and all categories. It weighs 160 kg and is produced in Cangzhou, Hebei. Through this equipment, it is possible to simulate the impact situations that office chairs may encounter during actual use, test the strength and durability of their chair surfaces, and provide an important basis for the quality assessment of office chairs.

Testing Platform

The Hebei Provincial Special Customized Furniture Product Quality Inspection and Testing Center has strong furniture testing capabilities. The center has established 20 professional functional laboratories and is equipped with 236 sets of advanced domestic testing equipment. It has the ability to conduct full-item testing on 51 categories of furniture products and 557 parameters, achieving full coverage of the entire furniture industry chain testing. Enterprises can send office chair samples to this center for testing. The testing cycle has been shortened from half a month in the past to two or three days, greatly improving testing efficiency.

Since its commissioning, it has served more than 3,800 enterprise visits and completed nearly 5,000 batches of product testing, providing strong support for office chair testing in the Cangzhou area.

Stability Testing Methods for Swivel Chairs

• Static Stability Testing: Adjust the swivel chair to its most unstable state, apply a specified vertical downward load at the center of the seat, and maintain it for a certain period. Observe whether the chair topples over, tilts, or has component damage.
• Dynamic Stability Testing: Simulate daily dynamic actions such as suddenly standing up, sitting down, and swaying left and right. By repeatedly performing these actions, check whether the chair can maintain balance and whether there is excessive shaking or the risk of toppling over.
• Caster Stability Testing: Push the swivel chair to move on a flat ground and observe whether the casters roll smoothly without jamming or deviation. You can also apply a lateral force to the casters to check their ability to resist lateral displacement.
• Overall Structure Inspection: Carefully inspect the overall structure of the chair before and after testing, including the chair legs, supports, connection parts, etc., to check for signs of looseness, deformation, or damage.
