Many companies eventually ask themselves the same question: which documents require technical translation, and which can be treated as “standard” business content that only needs regular document translation. The distinction can be crucial, because in technical documentation, even a single mistranslated parameter, unit of measurement, or procedure description can lead to assembly errors, downtime, complaints, or even safety risks.
In this article, you will find a practical answer to questions such as: which documents require technical translation, which documents should be prepared for translation first, and how to tell whether your materials need the support of specialist technical translators.
Technical Translation: What Is It and When Is It Needed?
Technical translation is a type of specialist translation used for documents that describe how technical solutions and processes work, from machinery and installations to software and industrial technologies. These materials typically include user manuals and service instructions, parameter specifications, regulatory requirements, and documents that protect technical solutions, such as patent applications. In this type of content, accurate meaning, correct terminology, and genuine subject-matter understanding are essential, because the quality of the translation can directly affect user safety and the proper operation of equipment.
In practice, technical translation is needed, among other situations, when:
- you are launching a product in a foreign market (manuals, labels, compliance documents),
- you are carrying out an investment project with international partners (project documentation, specifications, reports),
- you are taking part in a tender process (tender specifications, technical requirements, contracts),
- you operate in a regulated industry (chemicals, energy, aviation, defence, medical sector).
Bireta operates as a translation agency specialising in projects for industry and business, delivering translations in line with ISO 17100 and ISO 18587 standards.
Technical Translation: What Types of Documents Does It Cover?
Below, we outline which documents most often require technical translation. In every case, these are materials where clarity is essential — including parameters, requirements, procedures, and safety information — and where consistent terminology matters, because it directly affects correct use, installation, servicing, and compliance with formal requirements.
User Manuals and Operational Documentation
These are documents intended for end users and service teams. They describe installation, start-up, operation, and safety procedures step by step, so they must be as clear as possible and fully consistent across the entire set of materials.
- user manuals
- installation and assembly instructions
- maintenance and inspection instructions
- safety instructions / emergency procedures
- quick start guide
- training procedures for operators and service technicians
Technical Specifications
A technical specification defines the requirements, parameters, and evaluation criteria (for example, acceptance criteria) for a product, service, or project deliverable. That is why precision of wording and consistent terminology are essential in technical translation.
- technical specifications of a product or solution
- technical and quality requirements
- acceptance, testing and approval criteria
- execution and delivery conditions (including scope and tolerances)
- requirements relating to documentation, labelling, delivery and transport
Datasheets and Product Data Sheets
These are concise documents in which numbers, tables, and component names play the main role, so even a minor change in wording or notation can alter the meaning of a requirement.
- datasheets and product data sheets
- catalogue sheets and technical catalogues
- parameter and compatibility overviews
- descriptions of functions, limitations, and operating conditions
- tables, charts, variant lists, and configuration options
Design and Engineering Documentation
These documents describe a solution from a design and engineering perspective, including what needs to be done and how it should be carried out. They often refer to drawings, standards, and calculations, so the translation must preserve both the logic of the content and the links between all parts of the documentation.
- technical descriptions, calculations, and interdisciplinary coordination documents
- construction, detailed design, and technical design documentation
- as-built documentation
- reports and supporting studies related to investment projects
- environmental decisions and environmental documents linked to the project
Technical Drawings, Schematics, and CAD Files
A drawing carries key information through labels, legends, and descriptions, so the translation must fit the layout and cannot disrupt text fields, callouts, or cross-references.
- technical drawings (mechanical, construction, electrical)
- schematics (for example electrical, hydraulic, and P&ID diagrams)
- legends, descriptions, callouts, and title blocks
- drawing schedules and lists (for example bills of materials)
Service and Maintenance Documentation
These are practical working documents, often used under time pressure, so they must guide the service technician step by step and remain consistent with the terminology used for parts and with the labels shown in diagrams.
- service manuals
- maintenance schedules and checklists
- troubleshooting and fault diagnostics
- calibration and testing procedures
- parts lists (BOMs) and component replacement instructions
Tender Documents, Terms of Reference, and Public Procurement Requirements
These are formal and technical documents that define the subject of the contract, the requirements, and the evaluation criteria. The translation must be clear, consistent, and fully aligned across the entire set of attachments.
- Terms of Reference / technical description of the contract subject
- tender documentation and technical appendices
- technical requirements and minimum parameters
- bid evaluation criteria and contract performance conditions
- questions and answers during the procurement procedure, as well as clarifications to the documentation
Standards, Technical Norms, and Regulatory Documents
These are normative materials in which definitions, conditions, and references are critical, so the translation must leave no room for interpretation or any change in the level of obligation.
- industry standards and internal company standards
- technical guidelines and execution specifications
- regulatory documents and compliance requirements
- quality procedures and system instructions
Safety and Compliance Documents
These documents are intended to confirm compliance with safety or quality requirements and to communicate risks and required procedures clearly and accurately.
- risk assessments and safety analyses
- health and safety instructions / safety procedures
- declarations of conformity and supporting documents
- test, inspection, and measurement reports
- acceptance, inspection, and quality control records
What Makes Technical Documents Difficult to Translate?
Technical documents differ from typical business texts because their main purpose is to inform and lead to a specific action. Based on them, someone must be able to assemble, start up, inspect, accept, or assess compliance of a product, system, or process. That is why technical translation leaves no room for stylistic freedom. What matters more than elegant wording is that the content is clear, consistent, and fully faithful to the meaning of the original.
In practice, this means, among other things, that:
- Terminology must be consistent. The same component, function, or parameter should be named in exactly the same way throughout the entire document and across future document versions.
- Figures, units, and technical notation must be accurate. Errors involving decimal separators, tolerance ranges, units, or abbreviations can change the meaning and cause real problems in use.
- The language of requirements and procedures must be precise. It must clearly distinguish between what is mandatory and what is recommended, while each step should follow a logical order and be easy to carry out.
- Cross-references and consistency between document elements are essential. Numbering, section titles, and references to tables, drawings, and appendices must remain correct, because users often move back and forth within the document.
- Format can be just as important as content. Table layouts, captions, text fields, short notices, and space limitations all matter, so the translation should fit the structure and preserve readability.
- These materials are often subject to audits and quality control. That is why it is not enough for the text to be linguistically correct. It must also comply with industry terminology and the company’s internal standards.
At Bireta, we take a process-driven approach to this type of content. We build glossaries, work with CAT tools, maintain terminology consistency across the entire project, and apply additional quality checks so that the final text is safe, accurate, and practical to use. We can also maintain your company-specific terminology, making future documentation updates faster, more consistent, and easier to manage.
What Documents Should You Prepare for Translation to Speed Up the Project?
If you want to avoid multiple rounds of revisions and shorten the turnaround time for your translation project, it is worth preparing:
- source files in editable formats instead of scans, whenever possible
- information about the target market, including the country and the target audience, such as service technicians, end users, or engineers
- reference materials, such as previous versions, drawings, photos, parts lists, and the manufacturer’s terminology
- a glossary or your company’s preferred terminology, if available (if not, we will prepare one while working on your project)
- formal requirements, for example whether you need a print-ready version, whether the file layout must be preserved, or whether second-linguist proofreading is required
At Bireta, projects are coordinated by a Project Manager, which helps organise the schedule and communication efficiently, especially in larger translation assignments.
