Casement Windows mechanics performance
Lock device (of hand) switch power: no more than 100 N (torque is not more than 10 n. m)
The heavy suspension crane: in the 500 N forces, the residual deformation is not more than 2 MM, specimens do not damage, still keep using the function.
Wing song: in the 300 N forces, to allow a do not affect the use of residual deformation, are not damaged, Casement Windows are still keep using the function.
Switch power: flat hinge page, is not more than 80 N, slippery hold hinge, not less than 30 N, is not more than 80 N
Switch fatigue: kdsbuilding experts lay out switch fatigue should be no less than 10000 times by the switch test, specimen and hardware products do not damage. the fixed place and glass layering don’t loose, still keep using the function.
Vigorously closed: by simulating the continuous level 7 switch 10 times, are not refund bad, still keep switch function.
Angle strength, averages are not less than 3000 N, the minimum average of not less than seventy percent
Window hold test, in the 200 N function, don’t allow displacement, joint profiles not burst.
