Machinery safety law has long asked what a machine can do to people around it. From 20 January 2027, it also asks what someone else can do to the machine.
The control system requirements in the Machinery Directive (2006/42/EC) were written for closed systems, before all machines were connected to one another and to the outside world. Times have changed, and the regulations are catching up. The incoming EU Machinery Regulation—Regulation (EU) 2023/1230—requires, where appropriate, control systems to withstand reasonably foreseeable malicious attempts by third parties that could lead to a hazardous situation.
The new Machinery Regulation establishes legal requirements for cybersecurity without prescribing a specific standard. And since many modern machines are also products with digital elements, enter stage left the EU Cyber Resilience Act (CRA), whose cybersecurity rules will apply in full from 11 December 2027. So these two regulations overlap, and work done for one can help you meet the other. But demonstrating this overlap is the 👉 manufacturer’s responsibility 👈 (that’s you). You can’t assume that “doing the CRA” automatically satisfies the Machinery Regulation. That’s an architectural trap that is all too easy to fall into.
So far, so straightforward, right? Well, to make things even trickier for engineering teams, the standards haven’t yet been fully harmonised between these two regulations. Most teams today must document direct engineering justifications showing how control systems withstand malicious interference and track software interventions. So, what should those justifications be built on? Enter our third player: IEC 62443. For machinery, the standards being developed to meet these requirements are converging on IEC 62443, the multi-part series governing security for industrial automation and control systems.
It’s a complex, evolving regulatory landscape. Whether you’re an asset owner, system integrator, or product supplier, trying to keep up the machinery business as usual while staying compliant and safe right now is hard. Our guide to EU Machinery Regulation 2023/1230, IEC 62443, and the CRA will help you to understand the intersecting regulations and standards, and what your responsibilities are as they’re developed, ratified, published, applied, and enforced 👇
