Chair Seating and Back Testing Machine GT-LB04-1 – A Detailed Introduction
The safety, stability, and durability of office chairs, dining chairs, leisure chairs, and seats used in public places are important indicators. Their ability to withstand repeated loads and long-term use directly affects user experience and product lifespan. Therefore, before chairs are officially launched into the market, strict and standardized testing and verification must be conducted.
Among the various testing devices, the Chair Seating and Back Testing Machine GT-LB04-1, with its excellent performance and wide applicability, has become an indispensable piece of equipment for furniture manufacturers and quality inspection institutions.
I. Chair Seating and Back Testing Machine Application
Chair Seating and Back Testing Machine tests the strength and durability of the seats and backrests by simulating the daily use loading of the seat.
The Chair Testing Machine is equipped with two drive devices, which can be individually controlled to repeatedly load the test points of the seat.
II. Comprehensive Test Items
1. Static load test for seat and backrest
By applying one-time gravity to the seat surface and backrest, it simulates the instantaneous pressure when a user sits down or when the backrest bears force, checking whether the chair structure can withstand the rated load.
2. Durability test for seat and backrest
By performing a large number of cyclic loading motions on the areas of the chair structure that are most prone to fatigue, this test evaluates its long-term durability to ensure the product does not deform, loosen, or break due to repeated force.
3. Static and durability test for the front edge of the seat
This test examines the strength of the front-edge structure to avoid the risk of breakage or collapse when a user sits on the edge of the chair.
4. Forward horizontal static load test for the backrest
This test simulates the force applied when a user leans forward, verifying whether the backrest can remain stable and safe.
5. Static load test for the headrest
Applicable to office chairs with headrests, this test assesses the strength of the headrest connection by applying pressure.
6. Forward and lateral static load tests for chair legs
Chair legs are crucial structural supports. By applying forward and lateral force, the test ensures that the chair will not tip over or break during use.
III. Compliance with International Standards
