The Techinical Committees (TCs) are the key bodies of standardisation. A TC is a group responsible for the development and drafting of standards which are then ratified by European Standards Organisations. All stakeholders interested in the draft standard are entitled to participate, but only representatives of National Standardisation Bodies have the right to vote in the Technical Committee. TCs are composed by experts in a specific field representing national committees, industry, professional associations, government, trade union and other stakeholders. SBS, in quality of stakeholder, can send experts to TCs as observers with the right to participate to debates.
