Applicability: This test applies to all types of the swiveling chairs.
Purpose of Test: to evaluate the ability of a chair to withstand heavy impact forces on the seat.
Office Chair Seat Rotating Testing Machineis designed for dynamic and cyclic durability seat test.
Main function
Chair Seat Rotating Testing Machine applies on all kind of office chair which with swivel platform. Used to evaluate the office chair to withstand repeated pressure and wear ability in rotation. It provide two mode of testing：
- Can set the clockwise and counter-clockwise angle(45°to 355°)
- 360°rotation single direction
EN 1335 Chair Swivel Test Procedure:
The base of the chair shall be secured on a rotating table with a test surface so that the rotating axis of the chair coincides with the rotating axis of the table. The upper part of the chair shall be loosely fixed in such a way as not to hinder the rotation of the base. Load the seat in loading point A with a mass 60 KG and in loading point with a mass 35KG or any equivalent loading which will result in the same downwards force and bending moment on the chair. The angle of rotation shall be 360° at a rate of (10 ± 5) cycles/minute, 120,000 cycles. Change direction after each rotation.
