Applicable standards

QB/T 2280-2016-6.6.7;BIFMA X5.1-2017- (7)

Test procedure

Slowly load to 11120 N, hold for 1 minute, unload;  then slowly load again to 11120 N, hold for 1 minute, and record the test procedure.

Features

1. The driving motor is servo motor,  which can maintain the constant pressure of the chair foot in plastic deformation state,  and the speed and stroke are fully controlled by computer.

2. Full computer automation operation, can write their own test program;

3. Equipped with A4 color printer, can print all kinds of report curve.

4. Adopt high precision imported ball screw for lifting and loading, the process is smooth.
