In Austria, around 4,000 experts in active committees develop standards for the domestic, European and global market. They represent the interests of the economy, consumers, research, administration and society.
Together with them, Austrian Standards – the Austrian competence centre for standards – finds solutions ensuring that everything fits together perfectly and life runs smoothly. Austrian Standards distributes know-how laid down in standards as quickly as possible so that people and the economy can profit from it.
Austrian Standards, established in 1920, is structured in the business divisions of development, consulting, publishing, training and certification and finances the standardization system by more than 80 per cent through the sale of its products and services. Its legal basis is defined in the Standardization Act (Normengesetz 2016).
