This European Standard defines the design and manufacture of aluminium and steel trusses used in entertainment technology. Entertainment technology is an interdisciplinary field with specific technology and unique safety requirements. There are places of assembly, staging and production areas for events and theatrical productions. Such locations include but are not limited to theatres, multi-purpose halls, exhibition halls, film-, television-, photography- and radio-studios as well as facilities in concert halls, museums, schools, bars, discotheques, open-air stages and other places for shows and events. In some cases, atypical non-performance places are also used. This standard does not cover individual, separate rigging hardware like shackles, wire ropes, slings and other lifting accessories.
