The hinge bears static load, and the upper hinge bears static load and bears torque. The composite hinge bears the actual bearing quality. After the external force of the suspension is added, the vertical position of the free end of the door sash does not change by more than 1.5 mm. The test piece will not be deformed or damaged and can be opened normally.

Hinge hinge rotation force should not be greater than 40N, repeatedly open and close. According to the actual bearing quality, after the door hinge is repeatedly opened and closed 100,000 times, and the window hinge is repeatedly opened and closed 25,000 times, the fan at the free end of the door and window in the vertical direction should not be greater than 2 mm, and the test piece will not be seriously deformed or damage.
