Other measurement devices may be used, provided they allow measurements with an uncertainty in accordance with 4.1.2.2;  a fan with means to vary the pressure difference across the device, covering the range of Table 1 given in 4.1.3. NOTE In order to avoid pumping effect, an adequate device may be added after the airflow meter. SIST EN 13141-2:2010
