What do European directives say about manuals?
European directives are a part of the national legislation of any member state, thus guaranteeing that any European directive is binding in any EU member state. Directives are very general in nature. For example, they state that manuals should be easily readable, also for elderly people. Directives do not tell you how to achieve such a goal.
Norms do. On a national level, one can ask national authorities to provide the relevant norms for any European directive. Whereas European directives are available at no cost, norms are typically available as a book containing tens of pages to be bought from a national norm institution. For example, the Dutch NEN 5509 norm from the National Norm Institute sums up the requirements for manuals, as does the DIN EN 82079-1 norm in Germany. Leaving aside the language they are written in, these norms are identical. They tell you how to translate the European directives into concrete requirements. For example, the norms tell you something what kind of chapters should be in a manual, or what font size would do in order for a manual to be readable.
The most important directives that relate to manuals are the Machinery Directive, the EMC Directive and the Low Voltage Directive. But there are other directives as well, depending on the category a product belongs to (toys, pressure equipment, and so on).
The Machinery Directive
In order for every machine to be legally sold in the EU, it has be in line with the Machinery Directive. Only then can a manufacturer or reseller affix the so-called CE mark to its product, signifying that it is built in accordance with the relevant European directive (the Machinery Directive in this case). The CE mark (Conformité Européeenne) is valid in the whole of the EU and in countries belonging to the so-called European Economic Area. Countries like Norway and Switzerland are in the EEA.
The Machinery Directive has quite something to tell about technical documentation. According to this European directive, a manual should be completely accurate regarding the description and the operation of the machine in question. In other words: if a manufacturer decides to change the color of a knob from yellow to orange, this should be reflected in the manual immediately.
Also, the manual has to be available in all the official languages spoken in the country where it is sold. For example, in Belgium, the manuals should become available in Dutch, French and German. These are all three official languages in the Kingdom of Belgium. It is also quite common in Belgium to include a fourth language in the manual: English. This has to do with the fact that Belgium is also a very internationally oriented country, hosting the capital of Europe (Brussels).
In certain instances, the Machinery Directive allows for instructions to be written down in English only. One could think of maintenance instructions that are meant for specialized personnel who work directly for the manufacturer or are explicitly trained by the manufacturer. As a rule of thumb, however, manuals can only be published in the local language(s) of the user.
The EMC Directive
‘EMC’ stands for ElectroMagnetic Compatibility. The European directive on EMC only has one goal: to make sure that no electrical product or system is susceptible to electromagnetic interference. Take aviation equipment that has to be shielded from the interference of cell phones.
In most cases, the EMC Directive allows for a manufacturer to call its product electromagnetic compatible without showing a report that states how he reached that conclusion. However, if asked, the manufacturer has to show technical documentation that makes clear that he indeed tried to achieve the goal of electromagnetic compatibility. Also, the manufacturer has to include instructions in its manual insisting that a user should only use its product within its intended parameters. This way, a user that would amplify a signal with external means is at fault, not the manufacturer itself.
The Low Voltage Directive
The Low Voltage Directive applies to all electrical equipment destined to be used with a nominal AC voltage between 50 V and 1,000 V and a nominal DC voltage between 75 V and 1,500 V. This European directive states that the user should be made aware of any potential danger resulting from any voltage present.
The manufacturer is entitled to publish such warnings on the electrical material or equipment itself, and/or in the manual. Since it is not always possible to publish warnings on the equipment or material itself, the manual will in most cases be the most important source for warning the user not to carry certain actions that could bring him in danger.
