Office Chair Stability Test Method
Dec 13, 2024
The stability test of office chairs is a key step to ensure that office chairs will not tip over or slide during use. Here are some common office chair stability test methods:
1. Seat impact test
This method is mainly used to test the durability and stability of the seat surface of the office chair when subjected to external force impact. The test process is as follows:
- Place the office chair on the workbench of the test machine.
- Apply impacts of different forces and directions.
- Use sensors and test equipment to monitor and record the deformation of the seat surface and any possible damage in real time.
Through this test, the stability and firmness of the office chair in actual use can be evaluated.
2. Vertical load stability test
This test method is used to evaluate the stability of the office chair under vertical load. The specific steps are as follows:
- Place the office chair on the test bench.
- At the center of the most unstable edge of the office chair, 50mm inward from the edge, gradually apply force vertically downward to the specified force value through the loading pad, or until at least one of the table legs is off the ground.
This test method ensures that the office chair will not tip over under normal use conditions.
3. Vertical and horizontal loading stability test
This method combines vertical and horizontal loading to fully evaluate the stability of office chairs. The specific steps are as follows:
- Place the office chair on the test base.
- Use a block to block the table leg of the most unstable side of the specimen to prevent the specimen from moving during the test.
- Apply a force of 100N vertically downward through the loading pad at the center of the side, 50mm inward from the edge.
- At the same time, apply a horizontal force outward on the table at the center of the side, and gradually increase the force to the specified value or until at least one table leg is off the ground.
This test method ensures that the office chair can remain stable under various conditions of use.
4. Chair and stool stability test
This test method is mainly used for stability testing of straight-back chairs and stools. The specific steps are as follows:
- Simulate the load-bearing conditions of chairs and stools during daily use, and the ability to resist tipping.
- It is composed of pneumatic systems and adjustment machinery, equipped with a force display system, which can display the loaded force value in real time.
This test method ensures that the office chair will not tip over under normal use conditions.
5. Japanese Standard JIS S 1204 Stability Test
This test method is mainly used to evaluate the forward stability of the chair, the lateral stability of the armless chair, and the lateral stability of the chair with armrests. The specific steps are as follows:
- The chair is tested for stability in different directions, including forward, lateral and backward stability tests.
- During the test, different usage conditions are simulated to ensure that the chair can remain stable under various usage conditions.
This test method ensures that the office chair can remain stable under various usage conditions.
Through the above test methods, the stability of the office chair can be fully evaluated to ensure that it will not tip over or slide during use, thereby ensuring the safety of the user.
