Low Voltage Directive

Why do these products require this inspection?

If you are planning to put electrical resources onto the market in the European Union, you need an EU conformity declaration for electronics products.

What does this norm signify?

Directive 73/23/EWG in connection with the 93/68/EWG Change Directive (defines the requirements for bringing electrical resources onto the market, also called "electro-products") lists all electro-products with a nominal voltage of 50 to 1,000 V ~ and 75 to 1,500 V ~..

Excepted from this are the devices listed in Appendix II of this Directive, such as for example

• Electroradiological and electromagnetic operations
• Electricity meters
• Electrical resources for use in explosive atmospheres
• Devices for radio interference suppression

Requirements

A conformity declaration in accordance with Appendix II of the Directive made by the manufacturer or its designated authorized agent.

Technical documentation in accordance with Appendix IV of the Directive provided within the EU by the manufacturer, its authorized agent or the marketing party/importer.

This technical documentation must comprise among other things:

• Inspection reports
• Inspection logs
• User manual
• Service documentation

This documentation must be retained for the purposes of checks by national authorities for at least 10 years from manufacture of the last product.

The visibly attached CE label in accordance with Appendix III of the EU Directive. It must be on the product, the packaging, the user manual or the guarantee certificate in a readable and permanent form.

CE label

Whether in the EU or a third country, every manufacturer must use the (CE: Communauté Européenne) ) label for all products falling within the scope of EU Directives. As a form of "technical passport", the CE label demonstrates compliance with the minimum requirements of EU Directives, which does not necessarily require the assistance of an inspection center. The label is not directed towards the user, but rather signals to the authorities that manufacturing corresponds to all applicable Community Directives and marketing can take place freely within the European internal market. Responsibility for attaching the CE label lies with the manufacturer (manufacturer statement) or its authorized agent within the EU. This means that the label does not constitute evidence of quality inspection but rather a solely administrative symbol.

The manufacturer produces a conformity declaration for products marketed in the EU, listing all norms relevant to the product for which compliance is being confirmed.

Although there is no obligation to do so, DSM regularly inspects its products for compliance with the Directives.
These Directives specify how much electromagnetic interference the device may emit and also up to what intensity external electromagnetic interference will not impair the functioning of the device.
For example, DSM devices are tested for voltage fluctuations (reduction to 70% for 500 ms) and do not impair the function with electrostatic air interference of 4kV.
Only when the product satisfies all criteria of the norms is the CE label assigned.

This also means that strictly interpreted, individual components cannot bear the CE symbol, as compliance with the norms also largely depends on additional components (housing, power supply, bus circuit boards, hard drive, CD-ROM, graphics card etc.). In addition, an individual component such as for example a slot CPU without power supply and housing cannot be inspected.
