This testing machine is used to determine the durability characteristics of sofa backrests, armrests, and seat surfaces, and can be applied to single price sofas, long sofas, and multi seat chairs.

Testing principle:
The mechanical performance test of sofas mainly tests the durability of the seat, back, and armrests of the sofa. During the experiment, a loading module of a certain shape and quality will be repeatedly loaded onto the surfaces of the seat, back, and armrest in the prescribed loading form and frequency. This experimental method simulates the daily use conditions to test the sofa's ability to withstand long-term repetitive loads.

QBT 1952.1 2003

The loading mass of the seat loading module is (50 ± 5) kg
2. Two modules are loaded on the back, with dimensions of 200 * 100mm. The force measurement system is 0-20KN and displays in real-time.
3. Two armrest loading modules with a diameter of ¢ 50mm. Force measurement system 0-20KN, real-time display.
The mass of the counterweight metal plate is (70 ± 0.5) kg
5. Seat height measuring device, with a diameter of ¢ 100mm and a measuring range of 2KN, can automatically test the compression values a, b, and c. Test speed: 100 ± 20mm/min
6. There are four operation modes: preloading test, height test, stage test, and manual operation.
7. Delta PLC main controller, Kunlun touch screen display.
8. The armrest loading module can be tested separately or simultaneously for the left and right armrests according to testing needs.
9. Air pressure input range: ≥ 5kg/cm2. Inlet pipe: ¢ 10.
10. Power supply: 220V, 50Hz
11. Volume (including control box): 200x140x220cm
