Several new definitions have been included in the 2025 edition of ISO 10218-2. Among those, important are the definitions of the different areas the Robot can be working.
[ISO 10218-2: 2025] 3.1 Terms and definitions
3.1.9.2 Maximum space. space that can be reached by the moving parts of the robot (3.1.1.2)
3.1.9.4 Restricted space. Portion of the maximum space (3.1.9.2) restricted by limiting devices (3.1.9.5)
3.1.9.3 Operating space. Portion of the restricted space (3.1.9.4) that is used while performing all motions commanded by the task program (3.1.4.1)
3.1.9.6 Safeguarded space. Space where safeguards (3.1.10.2) are active or where the perimeter safeguard (3.1.10.3) provides protection
The Maximum Space is the maximum area that the robot plus its workpiece can reach. It is the dangerous area generated by the robot.
The Restricted Space is the area where the robot movements can be limited, thanks either to Software-based limiting safety function(s) or thanks to Mechanical limiting devices.
The Operating Space is where the Robot is programmed to work. For example it picks a piece out of a Printing press and places it on a conveyor.
Finally, the Safeguarded Space is the area limited by virtual or phisical barriers (safeguards). In case the Safeguarded Space is larger than the Maximum Space, no Restricted Space is required.
