According to Regulation on European standardisation (EU) 1025/2012, a national standard is a standard that manufacturers can use to comply with national product safety laws and policies. According to Regulation (EU) 2019/515, when a product meets a local standard of an EU Member State, other Member States must accept the product on their markets as well. However, nationals standards must not contradict EN standards.
National Standardisation Bodies
The standardisation system in Europe is based on the national pillars, which are National Standardisation Bodies or CEN members. National standardisation bodies transpose European standards into identical national standards and withdraw conflicting standards. CEN’s National Members are the National Standardisation Bodies of the 28 EU Member States, the Republic of North Macedonia, Serbia and Turkey, and three EEA countries (Iceland, Norway and Switzerland). And, there is one member per country.
