4 Performance characteristics for residential ventilation components/products 4.1 General The results of product performance tests reflect the performance which is achieved by the product in service. A product shall therefore be tested as a complete assembly with all necessary components which affect performance. Accessories are sometimes available for a product as an option. Where accessories could affect performance, the product shall be tested both with and without those accessories. If any insect screen, filter or similar device is intended to be fitted in the product, then it shall be in position when the product is tested. 4.2 Externally mounted air transfer devices 4.2.1 Aerodynamic characteristics The aerodynamic characteristics (pressure/flow rate curve), shall be measured and stated in accordance with EN 13141-1 and EN 13141-9. 4.2.2 Equivalent area The equivalent area shall be calculated and stated in accordance with EN 13141-1 and EN 13141-9. 4.2.3 Free area The free area shall be calculated according to EN 13141-1 and EN 13141-9 with the product in the fully open position and installed according to the manufacturer's instruction. 4.2.4 Controls The manufacturer shall state which type of control is incorporated; e.g. manual control or automatic control according to pressure difference. For manual control the pressure/flow rate curve, equivalent area and free area when fully closed shall be stated under the same test conditions as for the fully open results. If the device is not closable then this shall be stated. NOTE Automatic control by humidity, occupancy or other stimuli is possible, but there is no agreed test method for products with these types of control. 4.2.5 Air diffusion These characteristics shall be measured and the results presented in accordance with EN 13141-1 and EN 13141-9.

Where tests with different methods on a single unit result in different classes, the product shall receive the higher/worst classification. According to this, the unit has only one of the alternative leakage classes. The tests for air flow/pressure curve and thermal performances shall not be made if the unit is not classified because of measurement uncertainty. 4.9.3.3 Classification of Mass Flow Balance During test procedures according to EN 13141-7, the balance of the units (MFB) shall be measured and the disbalance shall be calculated using the following formula and classified according to Table 6.
