IVDR localization is decided document by document and market by market. Regulation (EU) 2017/746 does not require every internal record to be translated into every EU language. It attaches language duties to specific items: the information that accompanies a device, the EU Declaration of Conformity, self-testing and near-patient content, and certain documents submitted for conformity assessment. A workable localization pipeline therefore starts with a country-and-document matrix, not with a translation queue.
The European Commission’s national language overview for IVDR is a useful starting point, but it is an informational reference rather than the governing law. The most recent revision reviewed for this article is labelled Rev. 2 (August 2024). Check the Commission page for a later revision before relying on any row.
Which documents carry language obligations
The table below maps the document classes a localization team usually handles to the provision that governs each one. Where the provisions reviewed do not state a universal language rule, the cell says so instead of filling the gap with an assumption.
Recommended Free Tools
| Document class | Governing provision | Language rule to verify |
|---|---|---|
| Device information, including labels and instructions for use (IFU) | Article 10(10) and Annex I, Section 20 | Official Union language(s) determined by the Member State where the device is made available to the user or patient. |
| Self-testing and near-patient testing information | Article 10(10) | Must be easily understandable and use the determined official language(s). |
| EU Declaration of Conformity | Article 17 | Translated into the official Union language(s) required by each Member State where the device is made available. |
| Documents submitted for conformity assessment | Article 48(12) | A separate rule from the manufacturer technical documentation. Confirm the exact wording of Article 48(12) and the national expectation for the submission. |
| Documents required under Articles 34 and 35 (notified-body designation and assessment) | Article 37 | Article 37 contains an express language rule for this context. |
| Manufacturer technical documentation | Article 10 and Annexes II and III | Not stated as a universal translation duty in the provisions reviewed. The language need is set by the authority or submission that requests the file. |
| Field safety notices | Listed in the Commission national overview; national provisions apply | Verify for each Member State. Not stated in the EU-level provisions reviewed. |
| Graphical user interface (GUI) text | No specific IVDR GUI article; national legislation may apply | Verify for each Member State and check as a separate category. |
The provisions behind the table
Three rules do most of the work for device-facing content. Article 10(10) requires the manufacturer to ensure the device is accompanied by the information in Annex I, Section 20 in the language or languages set by the Member State where the device is made available:
“Manufacturers shall ensure that the device is accompanied by the information set out in Section 20 of Annex I in an official Union language(s) determined by the Member State in which the device is made available to the user or patient.”
Regulation (EU) 2017/746 (IVDR), Article 10(10), EUR-Lex.
Annex I, Section 20 also sets the form of that information. The medium, format, content, legibility and location must suit the device, its intended purpose and its intended users. A label that is correctly translated but printed in an illegible format still fails the test.
Rank #2
Article 17 handles the EU Declaration of Conformity separately, and Article 48(12) handles documents submitted for conformity assessment. Article 37 adds an express language rule for the notified-body designation and assessment documents covered by Articles 34 and 35. These rules sit beside the technical documentation requirements in Article 10 and Annexes II and III, and they should not be merged into one translation instruction.
Because each rule has its own trigger, a localization lead should record the exact article for every item before choosing a language. A translation approved for the IFU does not establish the language of the Declaration of Conformity or of a conformity-assessment submission.
What the Commission overview gives you, and what it does not
The Commission’s document titled “IVDR – Language requirements for manufacturers – Rev. 2 (August 2024)” sets out national provisions for device information, self-testing and near-patient testing information, Declarations of Conformity, field safety notices, conformity-assessment documents and GUI. A companion Commission page explains that these MDR and IVDR tables are meant to help manufacturers understand requirements by country.
The overview has several limits that should appear in your process documentation:

- It is updated when Member State authorities inform the Commission of changes, so a row may lag behind a national change.
- The Commission services do not take responsibility for its correctness.
- The IVDR and national implementing provisions prevail over the table.
- It notes that Member States are not obliged to determine a specific language. It encourages manufacturers to consider another language, such as English, where safe use is not compromised, particularly for professional-use devices. That is an encouragement in the overview, not a permission that overrides a national rule.
- GUI requirements may arise under national legislation even though the IVDR contains no specific GUI article.
Use the table to decide which national publications to check and in what order. Do not use it as the final answer for any market.
Building the pipeline
The cited sources do not prescribe a software architecture for this work. The design below is an operational inference from the document classes and language rules above. Software can support each step, but no tool makes a translation compliant on its own.

1. Create a requirements register
Key each requirement by destination Member State, device or use context, document class, user group, required language(s), legal or official source, source date, reviewer and next review date. Keeping the register in one place lets regulatory affairs and localization leads see the same obligation. The fields are described in the table further down.
2. Separate the document classes
Track at least six classes separately: internal technical documentation; information accompanying the device, including labels and IFUs; self-test and near-patient content; the EU Declaration of Conformity; conformity-assessment submissions; and field safety notices. Treat GUI strings as a seventh category with its own check. Do not derive a language rule for one class from another, even when the text looks similar.

3. Control source revisions
Give every source document a stable identifier and revision number. Link each localized version to that source revision, the target market, the language, the translation and review status, and the release decision. This prevents an approved translation from drifting away from the current source without anyone noticing. When the English or original source changes, the linked translations should show as out of date rather than silently remaining valid.

4. Set terminology and linguistic review by content type
Maintain approved device terminology and consistent wording for warnings, limitations, intended purpose and user instructions. Warnings, contraindications and limitations are safety-critical content and should go to a qualified reviewer. Machine translation or vendor software can speed drafting, but the output still needs human review before release.
5. Gate release on current market rules
Before a new market release or a material change to a document, confirm the current national rule from an authoritative national source. Reconcile that rule with the Commission overview, then record the decision, the reviewer and the date. A release should not proceed on the strength of the Commission table alone.
6. Reassess when inputs change
Recheck market rules when you add a Member State, change the user group or intended use, change the document or the interface, or learn that an authority has updated its national requirements. Set a review date for each register entry so that a stale rule is flagged rather than discovered at audit.

Fields for the requirements register
| Field | What it records | Why it matters |
|---|---|---|
| Member State and device context | The destination market and whether the device is professional-use, self-test or near-patient | National rules and the language expectation differ by user group. |
| Document class | One of the classes listed in step 2 | Stops one class’s rule from being applied to another. |
| Required language(s) | The official Union language(s) identified for that market and document | Gives translators and reviewers a fixed target. |
| Legal or official source and date | The article, national publication or Commission row relied on, with its date | Shows what the decision was based on and when. |
| Source revision linked | The identifier and revision of the source text translated | Lets you detect drift when the source changes. |
| Reviewer and approval | Who checked the national rule and who approved the release | Creates an audit trail for each market decision. |
| Next review date | When the rule must be checked again | Catches national changes that the Commission table may not yet reflect. |
When a language rule cannot be confirmed
Use these branches when a release decision stalls. Each one prevents a common error of assuming the answer.
- No current national source can be found. Hold the release for that market and document class. Do not infer the language from the Commission table or from a neighbouring country.
- The Commission table shows English as an option but the national publication is silent. Escalate to regulatory affairs before using English. The overview’s encouragement does not settle the national position.
- The source changed after a translation was approved. Mark the translation out of date, re-review the changed passages, and repeat the release gate before shipping.
- A warning or limitation was machine-translated. Route that passage to qualified linguistic review. Do not release it on the strength of the draft.
- A new Member State or user group is added. Rebuild the register entries for that market from the national source, not from earlier entries for other markets.
Localization for IVDR documentation works best when each language decision can be traced to an article, a national source, a source revision and a named reviewer. The Commission table helps you find those starting points, but the decision itself belongs to the document class and the market.
