This standard BS EN 12239:2001 Ventilation for buildings. Air terminal devices. Aerodynamic testing and rating for displacement flow applications is classified in these ICS categories:
91.140.30 Ventilation and air-conditioning systems
This European Standard specifies methods for the laboratory aerodynamic testing and rating of low velocity air terminal devices for displacement flow applications, including the specification of suitable test facilities and measurement techniques. The standard gives only tests for the assessment of characteristics of the air terminal devices under non-isothermal conditions. This standard applies to Class IV air terminal devices as defined in EN 12238.
