Overview

The durability testing machine for office chair casters and casters/footrests with a base should be applied to seats with casters on the base. The purpose of the $r $n test is to evaluate the ability of the seat legs and casters to withstand fatigue stress and wear caused by the back and forth movement of the seat.

Scope of application:Should be applied to seats with casters on the base.

Test purpose:Office chair caster life testing machineisTo evaluate the ability of the seat legs and casters to withstand fatigue stress and wear caused by the back and forth movement of the seat.

Test setup:

1. Connect the seat or footrest with casters to a similar circulation device.

2. Test the seat on a smooth and hard testing platform with three obstacles attached.If testing an entire chair, place a weight of 102 kilograms (225 pounds) on the seat cushion. If using a structure for testing, the weight of the test combination (tripod combination, structure, and weight) should be equal to 102 kilograms (225 pounds) plus * the weight of the assembled chair. The rotation and turning of the tripod and casters should not be obstructed.

3. Adjust the stroke of the circulation device to ensure that its slide is not less than 762mm (30 '). The stroke of the circulation device should be oriented based on the foot wheel sliding over the testing platform and obstacles.

4. The circulation speed of the circulation device is 10+2 times per minute. A cycle should include one forward and one backward impact of the circulation device.

Test program:

1. Conduct a sliding obstacle test on the seat or chair legs for 2000 times, and then test on a smooth and hard test platform without obstacles for 98000 times.

2. Evaluate the product according to the acceptance criteria in 17.1.5.1.

3. After completing the cycle, apply a tensile force of 22 Newtons (5 pounds) to each caster on the centerline of the shaft.

4. Evaluate the product according to the acceptance criteria in 17.1.5.2.

Acceptance criteria:

1. Durability cycle

2. Should have no loss of functionality

3、ANSI/BIFMA X5.1-2002

Wheel tightness:

After applying a tensile force of 22 Newtons (5 pounds), the wheel and the tripod must not separate.
