Ventilation for buildings - Air terminal units - Aerodynamic testing and rating of constant and variable rate terminal units; German version EN 12589:2001
This standard specifies methods for the aerodynamic testing and rating of constant and variable flow rate terminal units suitable for use with air distribution systems. The terminal units considered are : -single and dual duct, - induction, - fan assisted induction (parallel and series), - Single ducht with integral diffuser. The test are designed to determine fully the aerodynamic performance of terminal units and provide a basis for the comparison of the suitability of such assemblies when correctly installed in an air distribution system.#,,#
