National Standards Organizations

ETSI works closely with each European country's national standards body or ‘National Standards Organization’ (NSO). About half of those NSOs are members of ETSI but all of them have a key role to play in our standards-making process and in other areas of our work. More details concerning NSOs are available via the ETSI Portal.


Standardization in ETSI is a voluntary activity carried out by, and for, all interested parties. Consensus is therefore a key element of this process.

In the approval of European Standards (ENs), the NSOs have the exclusive responsibility for carrying out the Public Enquiry (consultation with national industry) and submission of the national position (the ‘vote’) on the standard.

NSOs ensure the transposition of ENs into national standards, and ensure withdrawal at any conflicting national standard.

Valuable liaison opportunities

Through our relationship with our NSOs we also have opportunities to reach out to other organizations which can be very useful to us in our standardization work.

For example, many NSOs:

  • play an active role in other standardization bodies which may impact on our work.
  • are connected at a local level to industry in sectors beyond Information and Communications Technologies (ICT), which is increasingly important to us as our standardization activities broaden to include the integration of ICT into other sectors.
  • have good contacts with Small- and Medium-sized Enterprises and Micro-Enterprises, which can often be the home of technological innovation. NSOs can therefore act as an interface to potential new areas for standardization at an early stage in the development of the technology.
