The minimum distance to the hazard zone shall be calculated by using the general Equation:
S=(K × T)+C
Where:
S: is the minimum distance, in millimetres [mm]
K: is a parameter, in millimetres per second [mm/s]
T: is the overall system stopping performance, in seconds [s]
C: is the intrusion distance, in millimetres [mm]
The Equation used to calculate C depends on the orientation of the detection zone.
