THE LEGAL DEFINITION OF “ASSEMBLY”
For a production line to be considered an ‘assembly,’ three elements must coexist: a production connection, operational linking, and a common control system (e.g., a coordinating PLC). When these conditions are met, the entire line is treated as a single machine—whether for existing lines or those being made available to workers. Individual certificates for component units are no longer sufficient; an integrated overview is required, which only an expert can guarantee.
INTERFACE RISK ANALYSIS
The critical juncture lies at the interfaces. An in-depth analysis must evaluate what occurs at the connection points: does an emergency stop on Machine A also bring Machine B to a safe state? The certification of the assembly serves to neutralize risks arising from the integration, verifying the compatibility of control systems and the coordinated management of safety functions.
RESPONSABILITIES AND DUTIES OF THE MANUFACTURER
Anyone who assembles the line legally assumes the role of Manufacturer of the Assembly. This entails the obligation to compile a new Technical File, issue a comprehensive EU Declaration of Conformity, and affix a new CE plate to the entire plant.
In order to draw up the Declaration of Conformity, it is necessary to comply with the requirements set out in Annex II of the Machinery Directive (2006/42/EC).
In particular, the document must include:
- The Manufacturer;
- The person authorised to compile the technical file within the EU;
- The signatory of the Declaration of Conformity.
The signatory of the Declaration of Conformity assumes the burden and responsibility of ensuring the machine’s compliance with safety requirements for as long as the machinery remains on the EU market.
THE STRATEGIC SUPPORT OF ECM
It is therefore essential to rely on a Notified Body such as ECM, which guides the company through the bureaucratic process by drafting rigorous reports. This ensures that the person signing the Declaration of Conformity can do so with the full support of a team of subject-matter experts.

Legacy Medical Devices and Regulation 2023/607: Managing Compliance Risk
The current European regulatory landscape is undergoing a delicate transition. The introduction of Regulation (EU) 2023/607, which amended the deadlines of the MDR (Medical Device Regulation), has given manufacturers more time to comply with the new rules. However, the practical application of these extensions is highlighting several shortcomings. Many manufacturers of so-called Legacy devices (devices placed on the market under MDD certificates that are still valid or have expired under specific conditions) do not fully meet the requirements necessary to benefit from the transitional regime.
