3.1 Requirements regarding certified safety devices
The safety precautions against unintended car movements have been developed
further and are required as UCM as part of EN 81-20/-50 and EN 81-1/-2.
This standard applies for all new installations and modernizations from end of 2014.
In accordance with the new requirements, all elevators must be fitted with a
certified safety device, which prevents uncontrolled movements of the car/cabin
with the door opened at a level, but which brings the car/cabin to a stop within a
designated area as shown in the figure in any case.

residual space of at least 1.0 m between the
upper edge of the cabin and the stepping edge
of the shaft.
