Test method
4.4.2 Repeated opening and closing
After being repeatedly opened and closed 25,000 times, the operation was normal and it did not affect normal use. And it should satisfy the following
a) The operating torque of the gear-driven multi-point lockout should not exceed 1 N·m; The sliding force of the multi-point lock driven by the connecting rod should not exceed 15 N.
b) The wear of the working surface at the locking points and lock seats should not exceed 1 mm.
5.4.2 Repeated opening and closing
Install the multi-point lockers on the test simulation doors and Windows of appropriate dimensions according to the actual usage conditions for testing, respectively in the direction parallel to the window sash and perpendicular to the door and window sash
Apply a force of 10N simultaneously in the direction, with a test frequency ranging from 250 times /h to 275 times /h. After completing 5,000 test cycles, check and lubricate as required by the product manual.
