EN standards are applicable to various industries and sectors, including construction, electrical, machinery, medical devices, automotive, food safety, and many others. They provide guidance in numerous processes such as product design, manufacturing, testing, and certification. As a result, they facilitate the free movement and trade of products and services in the EU market.

EN standards are developed and published by organizations such as the European Committee for Standardization (CEN), the European Committee for Electrotechnical Standardization (CENELEC), and the European Telecommunications Standards Institute (ETSI).

EN standards are adopted and implemented as national standards by many countries in Europe. Therefore, these standards play a crucial role in ensuring conformity and facilitating trade for products and services in Europe.
