> **Quick answer —** EU machinery rules require instructions to be supplied in the official language of the member state where the machine is placed on the market. Language coverage therefore follows your market list, not a translation budget.[Vitra.ai Universe](https://www.vitra.ai/platform) keeps one approved technical vocabulary across every document.

## Language follows the market list

Machinery placed on the EU market has to arrive with instructions in the official language or languages of the member state where it is made available, and the declaration of conformity has its own language expectations.

Member states set their own acceptance, so the language list is decided by where you sell rather than by what a localization budget allows.

That makes scope a commercial conversation involving compliance, not a downstream task — and it is worth having before a distributor agreement is signed rather than after.

## What falls in scope

Document

Typically in scope

Instructions for use

Yes

Safety information and warnings

Yes

Declaration of conformity

Yes, with specific requirements

Maintenance and service instructions

Yes where supplied to the user

Marking and plate text

Per requirement

Internal technical file

Generally not user-facing

The technical file is worth naming because teams often assume everything must be translated. Much of it exists for authorities rather than users, and the obligations differ. Confirm the split with your compliance function per product and market. The specifics change and a general article is the wrong place to settle them.

## Original versus translation

Instructions carry a distinction between the original language version and translations of it, and translated versions are normally identified as such.

That matters practically: the original is the reference, so a correction has to start there and flow outward rather than being applied to one language.

## Making it survivable across a range

Manufacturers rarely ship one machine. A range shares safety content, maintenance intervals and general operation, so a shared [translation memory](https://www.vitra.ai/features/translation-memory) turns the tenth product's manual into mostly reuse.

Pin the vocabulary in a [glossary](https://www.vitra.ai/manufacturing/manufacturing-glossary) first — a term corrected after publication means reissuing every document containing it.

Use [document translation](https://www.vitra.ai/features/document-translation) so numbering, cross-references and figure anchors survive, then [quality control](https://www.vitra.ai/features/quality-control) with back-translation on the safety sections. Regulatory affairs signs off; the pipeline supplies consistency and a record. The wider pattern for content a regulator reads is [regulated content localization](https://www.vitra.ai/solutions/regulated-content-localization).

## FAQ

**What language must machinery instructions be supplied in?** The official language or languages of the member state where the machine is placed on the market. Member states set their own acceptance, so the list follows the markets you sell into.

**Does everything in the technical file need translating?** Generally not. Much of the technical file exists for authorities rather than users, and the obligations differ from user-facing instructions. Confirm the split per product with your compliance function.

**What is the difference between original instructions and a translation?** The original language version is the reference, and translations are normally identified as such. Corrections therefore start with the original and flow outward rather than being applied to one language.

**How can a manufacturer reduce cost across a product range?** With a shared translation memory. Safety content, maintenance intervals and general operation repeat across a family, so later products reuse most of their documentation.
