 Standards:

JG/T 215-2017 Building door and window hardware multi-point lock

-4.4.2 Repeated opening and closing

-5.4.2 Repeated opening and closing

4.4.2 Repeated opening and closing

After 25,000 times of repeated opening and closing, the operation is normal and does not affect the normal use. and should be satisfied:

a) The operating torque of the gear-driven multi-point locking device should not be greater than 1 N·m; The sliding force of the connecting rod-driven multi-point locking device should not be greater than 15 N;

b) The amount of wear on the working surface of the locking point and the locking place of the lock seat should not be more than 1 mm.

5.4.2 Repeated opening and closing

The multi-point locking device is installed on the test simulating door and window of the appropriate size according to the actual use state, and tested in the direction parallel to the sash and perpendicular to the door and sash respectively

Apply a force of 10*]N in the direction at the same time, the test frequency is 250 times/h~275 times/h, every 5 000 test cycles are completed, check and follow the product instructions

Book of requirements for lubrication. And the test is carried out according to the following method:

a) Measuring the operating torque of the gear-driven multi-point locker with a measuring tool with an accuracy of not less than 0.1 N·m; Measure the connecting rod with a gage with an accuracy of 1 N or higher

type drive multi-point locker sliding force;

b) Use a measuring tool with an accuracy of not less than 0.02mm to measure the spacing between the frame fans at the locked place before and after the test, and calculate the amount of change, which is the working surface
