This test bench is used to perform the Swinging Test on toilet seats. This test (described in the Chinese standard) verifies the durability of the seat's rim and hinges by applying alternating loads to the sides of the seat. The device consists of two cylinders, alternating in intervals and providing a fixed load. One cycle consists of applying the load from one side of the rim to the other. The test is controlled by cycle-by-cycle monitoring of the stress variables. The bench has a workstation.
