The EU’s new Machinery Directive (2023/1230) is changing the playing field for machine testing.
It clearly establishes that the software in machines is just as important as their mechanical components.
For control systems in mobile machinery, functionality testing alone is no longer sufficient.
The scope now includes safety, cybersecurity, traceability, and systematic quality assurance.
Software Is Now a Safety Component
A new directive defines that emergency stop logic, safety sensors, and robot motion limits must be designed in compliance with international safety standards (IEC 61508, ISO 13849). In safety-critical software, an error is no longer just a bug — it can be a real safety hazard. For high-risk software, third-party assessment will also become mandatory.
Cybersecurity Is Part of CE Marking
Cybersecurity can no longer be ignored. The regulation requires that software must withstand unauthorized changes and manipulation attempts. In practice, this means:
Quality Throughout the Development Lifecycle
The entire control system development must follow a systematic process:
If a software update affects machine safety, it may require a new CE assessment. This highlights the importance of risk management and regression testing at every stage.
AI Is Welcome — But Controlled
If a machine uses artificial intelligence, its behavior must be proven safe and predictable. This also ties into the EU AI Act, which introduces additional requirements for developing self-learning systems.
