UNI - Ente Nazionale Italiano di Unificazione (Italian National Standardisation Office) UNI (Italian National Standardisation Office) is responsible for standards in all sectors - industrial, commercial and tertiary, with the exception of the electrical/electronics field. The standards are documents defining the characteristics (in terms of size, performance, environmental effects, safety, organisation, etc.) of a given product, process or service relative to the state of the art and are the outcome of work undertaken by thousands of experts all over the word. In the specific field of seating, both for office and for public use, there are various standards that govern the production of products depending on the type of use to which they will be put.
