scope:

This European Standard specifies laboratory methods formeasuring the aerodynamic and acoustic performance characteristicsand energy consumption of assembled exhaust ventilation systempackages for a single dwelling. If a component of the package isnot physically linked to the others (e. g. externally/internallymounted air transfer devices), then it is assumed to have beentested according to the test method related to this component. Anexample of a typical exhaust package is given in Figure 2. Theobject of this standard is to provide tested characteristics for asystem package in worst case conditions. It is assumed that bettervalues are achieved on site when the system package is installed inaccordance with the manufacturer's instruction and within thelimits of the test conditions given in this standard. Safetyrequirements are given in EN 60335-2-80.
