LT-JJ02-B Strength testing machine for office chair backrest and armrest

Standard

QB/T 2280-2016; BIFMA X5.1-2017; EN 1335:2000

The product description

This machine is suitable for the comprehensive test of office chair armrest and backrest, for the test of the strength of office chair armrest and backrest. The armrest strength test is mainly used to detect the integrity of the armrest of all kinds of seats after being subjected to pressure. This test is to simulate its strength or bearing capacity under the condition of one-time or repeated load when it is in normal use and habitual misuse. It is used to test the strength of the product under the possible heavy load conditions, and to evaluate the compressive capacity of the armrest of the office chair along the horizontal and vertical directions. The backrest strength test is used to assess the chair's resistance to pressure, by simulating the pressure applied to the back of the chair when the user presses back.

Product features

1. This device is a multi-functional test device, and cylinder output force or displacement can be selected;

2. The output Angle of the cylinder can be changed by sliding the position of the fixed pulley;

3. The loading pad is bound to the back of the chair, and the cylinder is connected with the ribbon. After the cylinder is unloaded, the back of the chair will naturally recover to its original state by its own elasticity;

4. Precise manual pressure regulating valve ensures stable and reliable cylinder output force, and digital display cylinder output force value;

5. Fix the test sample with l-type gear plate and chair press plate, and keep the pressure tight with manual screws;

6. The RPM speed is displayed and can be adjusted continuously;

7. Touch screen +PLC, with power off memory and breakpoint stop function.
