Technical Translation: A Complete Guide to Documents, Risks and the Expertise You Need

Technical translation is one of the most requested, yet least understood, translation services. Unlike general text, a technical document contains specialised terminology, standards, units of measurement and instructions that must be rendered with absolute precision — a single ambiguous phrasing can lead to usage errors, equipment failure or even accidents.

In this article we explain what technical translation involves, which types of documents fall into this category, why it’s essential for the translation to be carried out by a subject-matter specialist, and how the Viatrad team works to guarantee accuracy on every project.

What is technical translation

Technical translation is the process of converting, from one language to another, documents that describe products, equipment, industrial processes or technologies. It isn’t just about converting words — it’s about understanding how something works: how a piece of equipment operates, what a given technical parameter means, and what risks a mistranslated safety instruction can create.

For this reason, technical translation requires a translator who knows both the source and target languages, as well as the specific field of activity — mechanical engineering, electrical engineering, IT, energy, construction, automotive, medical or industrial chemistry.

Which documents fall under technical translation

The most frequent technical translation requests we handle at Viatrad include:

• User manuals and operating instructions for equipment and machinery
• Safety data sheets (MSDS/SDS) for chemical substances and products
• Technical specifications and product catalogues
• Documentation for tenders and infrastructure projects
• Standards, certifications and compliance reports (ISO, CE)
• Occupational health and safety (OHS) documentation
• Technical drawings, plans and annotated diagrams
• Patents and intellectual property documentation

Each category has its own terminological particularities, which is why we always select translators with proven experience in that specific field, not just native speakers of the target language.

Why translator expertise matters, not just language fluency

A common misconception is that any fluent translator can produce a quality technical translation. In reality, a translator without technical training may:

• mistranslate units of measurement or dimensional tolerances
• use generic terms instead of the standardised technical terminology for the field
• miss critical nuances in safety instructions
• create inconsistencies between the translated version and the original drawings/diagrams

These errors can lead to additional costs, production delays, or even rejection of the documentation by certification authorities. That’s why, at Viatrad, every technical project goes through a translation + specialist review process, carried out by linguists with experience in the relevant field.

How Viatrad works on technical translation projects

Our process is structured to guarantee terminological consistency and accuracy, regardless of project size:

1. Document analysis — we determine the technical field, target language and formatting requirements (including DTP, if the document contains drawings or graphics).
2. Assigning the right translator — we select a linguist with specific experience in the project’s technical field.
3. Translation and review — every document is checked by a second specialist, for terminological consistency and accuracy.
4. Delivery in the requested format — we preserve the original formatting (Word, PDF, AutoCAD, Excel, etc.) and offer DTP editing on request.

We work in 55+ languages and collaborate with translators specialised across a wide range of technical fields, allowing us to take on complex projects regardless of industry or volume.
