This European 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 duct with integral diffuser.
The tests for each type of unit are summarized in Figure 1.
The tests in this standard 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.
