This European Standard specifies structural classifications for floor mounted Air Terminal Devices (ATD’s) in respect of their possible applications and the following related structural test methods: a) Static test methods. b) Impact test methods. c) Dynamic test methods. Electrical continuity requirements for platform raised floor systems and components are not covered in this standard. Requirements for aerodynamic and acoustic testing of air terminal devices are not covered in this standard. The standard does not deal with any simulations relating to the wear characteristics of Air Terminal Devices.
