The European Standard (EN) is a set of guidelines and specifications developed to ensure quality, safety, and efficiency across various products and services in the European Union. These standards are created by the European Committee for Standardization (CEN) and cover a wide range of sectors, including construction, electronics, and healthcare. EN standards help facilitate trade and improve consumer protection by providing a common framework for manufacturers and service providers. Compliance with these standards is often voluntary, but they can become mandatory when referenced in legislation or regulations, ensuring that products meet essential safety and performance criteria.
