In the European Union, directives, regulations, national laws and standards form the basis for the regulation of products and their safety. EU directives and EU regulations set out the legally binding requirements that manufacturers must meet to enable them to place their products on the European single market.
European standards (EN standards) play a key role in the practical implementation of these requirements. Although in principle standards are not legally binding, they do describe the current state of the art and science. They provide manufacturers with specific technical solutions to ensure compliance with legal requirements.
As soon as standards are published in the Official Journal of the European Union, they are regarded as harmonised standards. When they are applied as part of an EU conformity assessment procedure, they lead to "presumption of conformity". This means that manufacturers can assume that their product meets the essential health and safety requirements of the respective EU directive or EU regulation.
Another advantage for businesses: when directives, regulations and harmonised standards are applied correctly, then the burden of proof may be reversed in the context of product liability. In the event of an incident, the relevant market surveillance authorities or the public prosecutor’s office must then prove that the legal requirements were not met.
