Technical and CE Documentation: What Brno’s IT and Engineering Firms Need to Translate
Brno’s engineering and IT firms export across the EU, and sooner or later that means translating something — a manual, a declaration of conformity, a spec sheet. The confusing part is knowing which documents actually need a sworn translation with a court stamp, and which just need accurate professional translation. Getting this wrong either costs you unnecessary certification fees, or worse, fails a market surveillance audit. This guide covers both.
For a general overview of certified translation in the Czech Republic, see our full guide.
In short
- Manuals, specifications and CE documentation almost always need professional translation, not a sworn (court-stamped) translation.
- CE documentation has three different translation rules: the technical file, the Declaration of Conformity, and the instructions — and they’re not the same.
- The Declaration of Conformity must be translated, not just the manual — a mistake we see often.
- Machine translation is a real compliance risk for safety-critical technical content.
Sworn or professional? Technical documents rarely need the stamp
This distinction alone can save a company real money, and it’s one of the most common points of confusion we see.
Sworn (certified) translation — the kind with the round stamp of a court-appointed translator — is a legal requirement only for documents submitted to Czech authorities or courts: contracts filed with the Commercial Register, documents supporting a foreign employee’s residence permit, and similar official submissions.
Manuals, technical standards, specifications, and software UI, on the other hand, almost never need that stamp. What they need is professional translation with accurate, consistent terminology — the stamp adds no legal value here, since no Czech authority is going to ask for it.
| Professional translation | Sworn translation | |
|---|---|---|
| Typical documents | Manuals, specs, UI, CE documentation | Contracts for the Commercial Register, employee documents |
| What matters | Terminological accuracy | Court stamp, legal certification |
| Required by | Nobody — a quality standard | Czech authorities and courts |
Companies sometimes ask us to certify a translated manual because they assume anything official needs a stamp. For technical documentation, that's usually unnecessary — what actually matters is that the terminology is correct and consistent, not that it carries a court seal.

CE documentation isn’t one document with one translation rule — it’s three, and they don’t all work the same way.
| Document | Translation rule |
|---|---|
| Technical file | Can be kept in a single language; provided to the market surveillance authority on request; kept for 10 years |
| EU Declaration of Conformity (DoC) | Must be translated into the language(s) required by the country where the product is sold |
| Instructions / user manual | Must be provided in the language of the country where the product is sold |
The most common mistake we see is treating the Declaration of Conformity as translation-exempt — companies translate the manual carefully and leave the DoC in English for every market. That doesn’t satisfy most directives: the DoC must be available in the language required by the destination country, even though it’s often a short document. Official guidance on both the technical file and the Declaration of Conformity is available via the EU’s official business portal.
When the DoC must travel with the product?
For most products, the Declaration of Conformity only needs to be produced when a market surveillance authority asks for it. For a specific group of product categories, though, the rule is stricter.
Directives covering machinery, potentially explosive atmospheres (ATEX), radio equipment, measuring instruments, lifts, recreational craft, and rail systems require that the DoC physically accompany each product — not just be available on request. For Brno’s manufacturing and engineering firms, many of which fall under the Machinery Directive, this is worth checking directive by directive rather than assuming.
We work with a few manufacturers in Brno where the DoC genuinely has to ship with every unit, not just sit in a file somewhere. It's a detail that's easy to miss if you're used to treating all CE paperwork the same way, and it's exactly the kind of thing a market surveillance check picks up on.
Dariaoffice manager KB PŘEKLADYWhy machine translation fails compliance audits?
For safety-critical content specifically, this is where the real risk sits — and it’s not always obvious until an audit happens.
Machine translation tools produce output that often reads as plausible but is unreliable for precise technical terminology. A safety instruction that looks grammatically fine in the target language can quietly shift meaning — turning a mandatory step into something that reads as merely advisory, for instance. National market surveillance authorities reviewing documentation are checking for terminology that matches the applicable harmonised standards, and inconsistent or imprecise wording is exactly what gets flagged. For recurring technical documentation, we build a glossary and translation memory per client, so terminology stays consistent across every manual, spec, and revision — not just within a single document.
Working with a translation partner
For companies that need technical and CE documentation translated regularly, a one-off arrangement rarely makes sense.
We work with several Brno-based IT and manufacturing companies under a framework agreement — signed once, covering all future orders, with standard 14-day invoicing terms and no minimum volume. A client-specific glossary and translation memory come as part of that setup, along with an NDA on request. Our office is on Příkop in central Brno, close to the city’s IT and engineering firms, and we offer express delivery within 24 hours even for business clients with recurring volume. For more on how framework cooperation works, see our business terms.
Frequently asked questions
Does technical documentation need a sworn translation?
Usually not. Manuals, specifications, and CE documentation need professional translation with accurate terminology. A sworn (court-stamped) translation is only required for documents submitted to Czech authorities or courts.
Which CE documents must be translated?
The Declaration of Conformity must be translated into the language required by the destination country. Instructions and user manuals must also be in that language. The technical file can be kept in a single language and provided on request.
Can I keep my technical file in English only?
Often yes — the technical file itself can typically be kept in one language and made available to the market surveillance authority on request, unlike the Declaration of Conformity and instructions.
Does the Declaration of Conformity have to accompany the product?
For most products, it needs to be available on request. For specific categories — including machinery, ATEX equipment, radio equipment, measuring instruments, lifts, recreational craft and rail systems — it must physically accompany each product.
How long must technical documentation be kept?
Technical documentation must generally be kept for 10 years from the date the last unit of the product was placed on the EU market.
Need technical or CE documentation translated for your Brno business?
We handle manuals, specifications and CE documentation with terminological accuracy — plus sworn translation where it’s actually required by law.
