The European Commission released the second version of the Artificial Intelligence Act实施细则 on 24 April 2026, introducing a new compliance requirement for industrial AI equipment placed on the EU market — including smart machine tools, automated packaging lines, and construction robots. This development directly affects manufacturers exporting such equipment to the EU, particularly those based in China, and signals a tightening of operational transparency requirements for high-risk AI systems in industrial settings.

Event Overview

On 24 April 2026, the European Commission officially published the second version of the implementing rules for the AI Act. It specifies that all industrial-grade AI devices intended for placement on the EU market must incorporate an embedded ‘human-machine collaborative operation log’ module compliant with EN 301 549 v3.2. The module must record timestamps of human intervention, instruction types issued, and system response status. Certification by TÜV Rheinland or DEKRA is mandatory. Chinese equipment manufacturers failing to complete firmware updates by Q3 2026 will be ineligible for CE marking.

Which Subsectors Are Affected

Direct Exporters of Industrial AI Equipment

Manufacturers exporting smart machine tools, automated packaging systems, or construction robots to the EU are directly subject to the new requirement. Their products must now integrate certified logging functionality before CE marking — meaning existing product lines may require hardware-compatible firmware revisions, not just software patches.

Industrial Equipment OEMs and System Integrators

OEMs embedding AI modules into larger production systems (e.g., CNC controllers with adaptive learning, robotic welding cells) face cascading integration obligations. If their AI subsystems lack compliant logging, the entire end-product fails the CE conformity assessment — even if other components meet applicable directives.

Firmware and Embedded Software Developers

Suppliers responsible for low-level firmware or real-time OS layers must ensure traceability architecture aligns with EN 301 549 v3.2’s accessibility and auditability provisions — especially regarding timestamp accuracy, non-repudiation of logged events, and secure storage integrity.

CE Marking Consultants and Notified Bodies

Conformity assessment bodies supporting Chinese exporters must now verify both functional implementation and certification validity of the logging module. TÜV Rheinland and DEKRA are named as designated certifiers; other Notified Bodies cannot issue valid certification for this specific requirement under current rules.

What Relevant Enterprises or Practitioners Should Focus On — And How to Respond Now

Confirm device classification and scope applicability

Not all AI-enabled industrial equipment falls under the ‘high-risk’ category triggering this mandate. Companies should cross-check their product’s intended use and autonomy level against Annex III of the AI Act — only systems explicitly listed (e.g., AI used in safety-critical control loops of machine tools) require the log module. Avoid over-compliance where not legally mandated.

Verify firmware upgrade feasibility and timeline alignment

Assess whether existing hardware supports EN 301 549 v3.2–compliant logging without hardware modification. If legacy controllers lack secure timekeeping or tamper-resistant storage, retrofitting may require board-level redesign — making Q3 2026 deadline unattainable without prioritized engineering resources.

Initiate engagement with TÜV Rheinland or DEKRA now

Certification lead times for embedded modules are typically 8–12 weeks. As demand surges post-announcement, early engagement helps secure slots and clarify test protocols — especially around edge cases like intermittent connectivity or offline logging persistence.

Document internal change control processes for future audits

The log module is not a one-time fix: any subsequent firmware update affecting timing logic, instruction parsing, or event serialization must undergo re-certification. Maintain version-controlled records of logging behavior changes to support ongoing CE maintenance.

Editorial Observation / Industry Perspective

From an industry perspective, this update is less a sudden regulatory shock and more a formalization of enforcement expectations already emerging from pilot assessments under the first AI Act implementing rules. Analysis来看, the focus on human-machine interaction logs reflects the EU’s prioritization of accountability over pure performance — shifting compliance emphasis from ‘what the AI does’ to ‘how humans oversee it’. Observation来看, the explicit naming of TÜV Rheinland and DEKRA suggests deliberate capacity management, possibly to avoid certification bottlenecks across competing bodies. Current更值得关注的是 how national market surveillance authorities interpret ‘system response status’ — whether it includes latency metrics, confidence scores, or fallback mode triggers — as that definition will shape test case design.

It is better understood as an operational signal than an immediate market barrier: while non-compliant devices lose CE eligibility after Q3 2026, no retroactive withdrawal of already placed equipment is stipulated. The mandate applies prospectively to new units placed on the market — giving exporters a defined window to adapt.

In summary, this rule crystallizes the EU’s stance that industrial AI must be inherently auditable at the point of human interaction. Its significance lies not in novelty of concept — logging has long been part of functional safety standards — but in its statutory elevation to a CE prerequisite. For exporters, it reinforces that AI compliance is no longer solely about algorithmic robustness, but also about verifiable human oversight infrastructure.
