Product Detail
The chair stability tester is suitable for all kinds of office chairs, stools and other seating products. It can test the mechanical properties of forward stability and backward stability at room temperature. It is widely used in the office chair furniture industry to evaluate the stability of products, improve the quality of products..

Applications：
1.Prior to stability test: place the sample on the platform, mobile block is 13 mm, to prevent the wheels placed before loading plate at a face stability, through the cylinder drives the lifting weights, using special fixture surface center position here from the leading edge of 60 mm 610 n force, at the same time places 20 n levels of tension on the back of a chair, evaluate samples prior to stable performance.Load under defined deformation: Test load under defined deformation of tested sample.
2.Software Backward stability test: place the sample on the platform, move the 13mm block to prevent the wheel sliding, if the height of the back of the chair is not enough to place the loading plate, increase the block close to the chair surface profile for test, apply 1300N force on the surface of the table, at the same time apply horizontal thrust 6mm from the top to evaluate the backward stability performance of the sample.
