The working committee NA 149-00-05 AA "Machinery" is responsible for the development of standards for technical equipment for entertainment and theater technology. Technical equipment comprises technical systems and materials for event and production facilities that are used for lifting and lowering, holding and moving of loads (e. g., decorative parts, trusses, lighting, visual and sound devices). Both the movement of people by these installations, as well as being under stationary and moving loads are allowed. Safety requirements are an essential part of the standardization work.
