International Standard for Language in Manuals
Manuals must enable the safe use of products. Global standards have been developed for this purpose, with the most important being IEC/IEEE 82079-1:2019 — Preparation of information for use — Part 1: Principles and general requirements. This international standard states that information for use must be clear, understandable and tailored to the target audience. Instructions should be concise and clearly formulated.
The standard does not explicitly require a manual to be written in the local language. However, it does emphasise that users must be able to fully understand the content. In practice, this often means that a manual in the native language is preferable, especially for consumer products.
Language of Manuals Within the European Union
Within the European Union, IEC/IEEE 82079-1 is recognised as the key standard for creating clear and legally compliant instructions for use. However, European product legislation and national regulations determine in which language user information and warnings must be provided.
For products placed on the European market, manufacturers must always consider the language requirements of each individual country. In particular, warning texts and safety instructions must be available in the official language or languages of the country concerned. This is necessary to comply with legal requirements and to ensure product safety.
Examples of National Regulations
In the Netherlands, the Commodities Act requires that user information and safety warnings are provided in Dutch. In Germany, this is regulated by the Produktsicherheitsgesetz (ProdSG), and in France by the Code de la consommation. In countries with multiple official languages, such as Belgium and Switzerland, manuals must be available in all official languages.
Complying with these language requirements is essential for both user safety and legal compliance within the European Union.
Latin Alphabet Versus Other Alphabets
The Latin alphabet, with its 26 letters, is the most widely known alphabet worldwide and is used for the English language. Although it is widely used, it is not the standard everywhere. In countries such as Russia, China and various Arabic states, other writing systems are used. Instructions in English or another language using the Latin alphabet are often insufficient in these regions, as users may not be able to read the script. In many of these countries, it is therefore mandatory to adapt the language of manuals to the local alphabet and native language, in line with IEC 82079-1.
In some cases, English-language manuals are permitted, for example for technically trained personnel in countries where English is widely used alongside the native language. However, strict additional conditions often apply.
Advantages of a Manual in the Native Language
A manual in the native language reduces the risk of misunderstandings and errors. Technical terms may have different meanings across languages, which can lead to unsafe situations if instructions are interpreted incorrectly. Using the correct language prevents confusion, increases safety and ensures that products are used more efficiently.
What to Consider in Africa and Other Multilingual Regions
The African continent has a complex linguistic landscape. In addition to English, French and Portuguese, many local languages are used. The official language varies by country, and some African countries are not members of international standardisation bodies.
As a result, language requirements differ significantly by region and product. It is therefore essential for companies to assess the specific language requirements for manuals in each country.
Localisation: More Than Just Translation
Creating a correct language version of a manual involves more than simply translating text. Local conventions, formats, symbols and technical terms must also be adapted to the target language.
Differences between British English and American English, or between European and Latin American Spanish, can lead to misunderstandings. Localisation ensures that the manual is not only technically accurate, but also culturally and legally appropriate for the local market.
Why Professional Translation and Localisation Matter
Incorrect or unclear translations increase the risk of misuse, damage or even accidents. Specialist translators and technical writers ensure that your translated manual meets all local and international requirements. They are familiar with relevant standards, legislation and cultural differences.
This ensures that your manuals are clear, safe and usable for all users.
