R&D under EU machinery law — where the regulatory frame begins

EU machinery law never regulates research. There is no R&D permit, no laboratory registry, no notification duty for building a prototype. What the law regulates is three precisely defined events — and everything an R&D programme does before those events is legally silent territory. That silence is not a loophole; it is the design. But its edges are exact, and the most expensive R&D mistakes in this trade are edge mistakes: the pilot that was actually a sale, the field trial that was actually a putting into service, the machine built "just for ourselves" that was covered all along.

This guide draws the boundary. It is written for machine manufacturers — wherever established, inside the EU or outside it — and the people who help them; every rule on this page binds an EU manufacturer exactly as it binds one in Jinan or Ohio. It applies the same reading rule as the rest of this site — which version of the text you read is part of the answer — and it is information, not legal advice.

The three events, in the law's own words

Free of charge counts. Each individual unit counts separately. And putting into service reaches machines that were never sold at all — which is the clause most R&D surprises come from.

The corridor: what is not a trigger event

Each item below is an activity an R&D programme actually performs, and each is expressly outside the frame — with its conditions:

• Prototype work inside the manufacturer. Placing requires an agreement transferring the product after the stage of manufacture is complete. A prototype under development never reaches that stage — and a contract to develop a machine to agreed specifications is not a placing either.
• Pre-production validation. Units "transferred for testing or validating pre-production units considered still in the stage of manufacture" are not placed. The qualifiers carry the meaning: still in manufacture, transferred for testing — not for revenue.
• Trade fairs, exhibitions, demonstrations. A non-conforming machine may be shown, on conditions both regimes state expressly: a visible sign that it does not conform and will not be made available until it does, and measures to protect persons during demonstrations. Under controlled conditions — expert operators, restricted public contact — it may even be operated. What the allowance never covers is selling it (see below).
• Development for other markets. Supply aimed at exporting the final product outside the EU is not a making available — and that includes goods manufactured in a Member State with a view to export. Development for non-EU markets never enters this frame, wherever the manufacturer sits — until an EU buyer is targeted.
• A non-compliant machine can lawfully enter the EU — under a special customs procedure: transit, customs warehousing, temporary admission, inward processing. This is the sanctioned route for bringing a machine in for a fair, for evaluation, or for the compliance work itself. It is declared for release for free circulation only after it has been made compliant.
• The laboratory exclusion. Machinery "specially designed and constructed for research purposes for temporary use in laboratories" is excluded from the machinery instrument entirely. Read it as the two-part test it is: the machine must be purpose-built for research (a production machine bought by a lab is not excluded — the exclusion follows design intent, not the buyer), and its laboratory use must be temporary (a rig that becomes permanent lab equipment, or leaves the lab, exhausts the exclusion). And exclusion from machinery law is not exclusion from all law — electrical, electromagnetic-compatibility and national workplace rules still attach on their own terms.

Where the corridor ends: the five expensive surprises

1. Building a machine for your own factory is covered. For machinery, own use is expressly within the frame: a machine you manufacture for your own production line must demonstrate full conformity at its first use. "We never sold it" is not a defence — putting into service is its own trigger. (The only surviving carve-out is occasional manufacture by a private person for non-commercial use.)
2. An employer's first use is a putting into service. A field trial where your machine runs in a customer's production is, in the law's eyes, the trigger event — whoever owns the machine on paper, however the trial is framed commercially.
3. A paid pilot is a placed product. The pre-production carve-out covers units still in the stage of manufacture transferred for testing. A pre-series unit sold or leased to a reference customer who uses it productively is placed, and must fully conform. A discount does not change the analysis.
4. The fair is a display licence, not a sales licence. Sell the exhibit — or leave it installed with a buyer afterwards — and it is placed.
5. Second-hand does not launder. A used machine imported into the EU is placed for the first time at import, and must meet the law applicable at that moment — even if it was manufactured before that law existed. (A used machine already lawfully on the EU market is different: reselling it inside the EU is not a new placing, and it keeps the conformity of its original placing date — unless it is substantially modified, which makes the modifier the manufacturer of a new product. And a machine placed in the EU, exported, and later re-imported is not placed again. The question is never the machine's age, but whether the individual unit was ever lawfully on this market — and never where it was built: EU-made and non-EU products "are treated alike". An EU-built machine exported before it was ever placed gets no homecoming discount; bringing it back is a first placing, under current law.)

The frame reaches back into R&D anyway

Even while no trigger event has occurred, five mechanisms make the frame a design input rather than a downstream formality:

• The acceptance criterion is the state of the art — and it moves. What was adequate at design freeze can be a non-conformity by the time of placing. Tracking it is R&D work.
• The risk-reduction order is binding: eliminate by design first, guard what remains, only then warn. That is a constraint on engineering choices, not on paperwork.
• The modification envelope is authored in R&D. What your instructions foresee is not a "substantial modification" when done later — writing that envelope is design work with direct legal effect.
• Safety-relevant software updates are regulated events. The substantial- modification definition reads "by physical or digital means" — release management of firmware for fielded machines is a conformity function.
• Architecture choices select the conformity route. A self-evolving machine-learning safety function moves that system out of self-assessment and into notified-body territory; cybersecurity and AI-Act certificates can carry part of the machinery argument. Evidence planning starts on the drawing board.

This guide is a high-level overview published openly by the LJUSA TIDER platform. It does not replace legal advice: whether a specific activity crosses the boundary depends on facts — contracts, intended use, what actually happens at the fair or in the field trial — that only you and your counsel hold.
