This standard defines the test methods to determine the forces to open/close doors and to lock/unlock the hardware using a key or handle.
It is only applicable to side-hung and sliding doors with latches in manual operation, for pedestrian use.
The measurement of forces for doors with self-closing devices engaged is excluded from this test method. It is also not applicable to doors with special hardware e.g. emergency exit devices.
Note: The operation of some windows involves latches and may be tested in accordance with this standard.
