Minor errors in technical documents are often considered trivial, but their impact can be far-reaching. In the world of engineering, a single incorrect term can alter how a machine is assembled, lead to misinterpretation of safety procedures, or cause a system to malfunction.
Furthermore, such errors can lead to legal risks when specifications are not met and damage a company’s reputation in the eyes of international clients.
Amid rapid global industrialisation and cross-border operations, the need for technical document translation services is growing. Companies now have to navigate cross-border standards, multilingual documentation, and increasingly stringent quality requirements.
However, many companies still consider translation to be a secondary task that can be handled without specialised expertise, even with the help of AI. As a result, important documents are often processed by AI without human review, which is precisely where these silent errors creep in.
Technical translation professionals can catch these details. With their understanding of terminology, industry context, and multi-layered verification processes, they can detect ambiguities, inconsistencies, and potential functional errors that machines cannot see.
What Makes Technical Translation So Easy to Get Wrong
Technical documents are not simply texts that can be translated word-for-word; they are complex logical systems. Every instruction, parameter, symbol, and writing style carries a specific functional meaning that must be thoroughly understood.
Imagine if the user guide for installing a washing machine were missing a single word of explanation, could lead to serious misuse or safety risk.
Even the most minor error can change the way a device or process is operated, posing safety risks and damaging the company’s reputation. This is why technical translation services require more than just language skills.
The main pitfall for inexperienced translators is focusing only on words or phrases, without understanding their actual function or purpose. For instance, warnings, operational instructions, or technical descriptions have specific intentions that must be preserved for the document to remain safe and effective.
Another common mistake is ignoring critical safety-related phrases such as “must”, “should”, and “may”, which distinguish between obligations, suggestions, and possible actions. Incorrect translations in these areas can result in procedures being misapplied, potential accidents, or device failure.
Technical translators understand that successful technical translation is not just about language, but about function. By examining the context, the author’s intent, and the terminology of the target industry, they capture important nuances that are easily overlooked, ensuring that documents remain accurate, safe, and reliable at all levels.
The Silent Errors No One Notices—Until They Matter
In the world of technical translation, minor errors can have a significant impact, but often go unnoticed until the document is used in the field.
Technical translators know that the biggest risk is not only incorrect language but also details hidden between words, in context, and in format.
1. Terminology Echoes That Don’t Match
Technical terms that appear lexically correct often confuse when applied in a system. For example, “bearing housing” may be translated as “rumah bantalan” in Bahasa Indonesia in one part of a document, but appear as “pelindung bantalan” in another.
Such minor differences can confuse technicians following assembly instructions, delaying the process or even damaging components.
In technical translation, terminology consistency is key to ensuring that each term refers to the same object or function throughout the document.
2. Cultural and Contextual Shifts
Errors also arise when terms are translated without considering the cultural or industrial context. For example, the word ‘tolerance‘ has a different meaning in engineering than in medicine.
At the same time, ‘hazardous area’ in the oil industry refers to a zone with a risk of explosion; in electronics, it can mean an area with high voltage. Without an understanding of the context, translations can be misleading and risky for the end user.
3. Unit and Symbol Ghosts
Units, symbols, and technical labels are often hidden pitfalls. Inconsistent unit conversions or symbols that appear correct visually in both languages can lead to operational errors. A simple example: pressure in psi translated to bar without updating the diagram, causing the user to read the wrong value.
In technical translation, attention to numerical details is as important as the words themselves.
4. Formatting Blind Spots
Technical documents rely on layout: diagrams, labels, and captions often carry critical information. Novice translators tend to focus only on narrative text, ignoring the visual context.
As a result, seemingly clear instructions can become ambiguous, and mislabelled diagrams can lead to assembly or tool usage errors.
These invisible errors serve as a reminder that technical translation is not simply a matter of replacing words from one language to another, but rather a comprehensive understanding of the system, context, and visuals.
Experienced technical translators check terminology, cultural context, technical conversions, and formatting to ensure that documents remain accurate, safe, and reliable.
Inside the Mind of a Professional Certified Translator
Professional certified translators think very differently from ordinary translators. They do not simply translate word-for-word, but understand the function, context, and risks of each text.
They structure their work habits to ensure accuracy, security, and compliance. Here is how the professional technical translator works:
1. Terminology Engineering
Instead of relying solely on static glossaries, professionals build dynamic term memories. Each project adds to internal references that help maintain term consistency in subsequent technical documents, especially in engineering fields full of specialized jargon.
2. Dual Reading
Professionals perform dual reading: first as readers, then as end users (e.g., engineer/operator). For example, engineers, doctors, or operators—to grasp the intent and function of the instructions. This approach prevents errors that can arise if the focus is solely on language.
3. Risk Awareness
We assess each section of text to determine its level of risk. You must check the phrase “safety-critical” repeatedly to prevent any misinterpretation of safety instructions and to protect both the device and its users.
4. Compliance Awareness
Professionals understand international regulations, such as ISO 17100, and sector-specific standards, including the EU MDR, IEEE, and ASTM. This knowledge ensures that documents are not only linguistically accurate but also legally compliant and in compliance with industry standards.
With this mindset, technical translation is not just a linguistic task, but a combination of linguistic and technical expertise and mature risk awareness.
How Technology Helps—But Never Replaces the Human Check
In technical translation, technology is an essential tool, but it cannot replace human judgment. CAT tools, QA software, and terminology databases help maintain consistency in terminology, speed up revisions, and check for formatting or spelling errors.
For example, CAT tools allow translators to save and apply the same terms throughout a document, while QA software highlights inconsistencies and potential duplications.
However, AI and machines are still limited in their understanding of domain context and legal risks. Machines can translate technical phrases literally—for example, ‘seal failure’ into ‘kegagalan segel’ in Bahasa Indonesia—but they do not know whether the term refers to a specific mechanical part or a leak in the entire system.
Errors like this can be highly consequential, especially in safety-critical or regulatory documents. In fact, they can lead to financial losses or legal problems.
Therefore, professional technical translators always perform manual checks. They verify the context, function, and compliance with industry standards, ensuring that every term is accurate and in line with the author’s intent.
Technology speeds up and supports the process, but human accuracy remains the final layer of protection. It is this balance between modern tools and human judgment that ensures technical documents are not only linguistically correct but also safe, reliable, and compliant with regulations.
The Business Cost of Overlooking Expertise

Ignoring the expertise of technical translators can have costly real-world consequences. Incorrect translations can damage products and trigger recalls or denied warranty claims.
In more serious cases, errors in technical documentation can cause workplace accidents, pose safety risks to operators, and significantly damage a company’s reputation. Beyond financial losses, companies may also face legal exposure.
Meanwhile, the cost of correcting incorrect documents—including revisions, reprints, and litigation—is often far higher than the initial investment in professional services. Certified technical translators will ensure that every instruction, label, and warning is accurate, consistent, and compliant with industry standards.
Hence, the initial cost of professional services is far more cost-effective than dealing with avoidable errors. Technical translation is a long-term investment for the industry, minimising language risks and real business risks that have financial and reputational implications.
