Product Details

Product description

This machine is used to test the durability of office chair armrests under cyclic side pressure (at an Angle of 10 degrees from the plumb line). Test armrest durability, front corner static pressure durability. This device is a multi-function test device, which can realize a variety of test functions by adjusting the direction of the output force of the cylinder.

Standard

It meets the requirements of QB/T 2280-2016, BIFMA x5.1-2017, EN 1335.2000, QB/T 2602-2013 and other standards.

Test method

Armrest fatigue test: Place the chair on the test floor. If there is a need to restrict the rotation of the seat, do not restrict the armrest when clamping. Adjustable height handrail must be adjusted to the most vulnerable position, when the most vulnerable position is not obvious, it is necessary to add several loading points to test the product. Adjustable width handrails must be adjusted to the most vulnerable position. (for example, take two points in front of armrest 100mm backward and apply force simultaneously. The handrail cover can be freely rotated, and the load must be applied to the pivot point, without restricting the rotatable handrail. The armrest loading device must distribute the load in the 100mm long area and load it on the inner side of the armrest. The distance between the center of loading force and the inner side of the armrest must not exceed 25mm. Place the loader where the handrail is most vulnerable to damage. At the same time will force of 400 n loading on each arm, load and vertical plane into 10°+1°Angle, if the armrest appears deviation or rotation, loading device must be adopt to achieve equivalent force and Angle of the other testing methods, follow the armrest as phase For the same action, the force must load and unload 60,000 cycles at a rate of 10-30 cycles per minute.
Front Angle alternating bending test: pressure block with 8 "diameter and 165 pounds weight is slowly and quietly pressed to the front or left of the chair at a speed of 10 ~ 30CPM.Angles 20,000 times each.

Product features

1. The cylinder output Angle can swing and change the position;
2. The loading pad is attached to the handrail under test, and the cylinder can choose to work without retracting to increase stability;
3. Precise manual pressure regulating valve ensures stable and reliable cylinder output force, and digital display cylinder output force value;
4. Casters fix the cup to fix the position of the chair, so that the chair can be tested in the natural state;
5. RPM speed is displayed and can be adjusted continuously.
