This European Standard specifies requirements and testing for ratings and performance of air handling units as a hole. It also specifies requirements, recommendations, classification, and testing of specific components and sections of air handling units. For many components and sections it refers
to component standards, but it also specifies restrictions or applications of standards developed for stand alone components.
This standard is applicable both to standardised designs, which may be in a range of sizes having
common construction concepts, and also to custom-design units. It also applies both to air handling units, which are completely prefabricated, and to units which are built up on site. Generally the units within the scope of this standard include at least a fan, a heat exchanger and an air filter.
This standard is not applicable to the following:
a) air conditioning units serving a limited area in a building, such as fan coil units;
b) units for residential buildings;
c) units producing ventilation air mainly for a manufacturing process.
