ČSN EN 12217 It defines the classification of the test results for the forces and/or torques to open/close doors and to engage/release and lock/unlock the building hardware using a key or handle, after testing in accordance with EN 12046-2. It is only applicable to the manual operation of doorsets. The classification of forces for doorsets with self-closing devices engaged is excluded from this test method. It is also not applicable to doorsets with special hardware, e.g. emergency exit devices. The tests are applicable to doorsets of any material. The operation of some glazed doors (door high windows) involves hardware with latches and may be classified in accordance with this European Standard.
