Measuring station Sound power level All acoustic data is established in keeping with DIN 45635 and ISO The direction of air flow is given as follows: 3744/3745 to accuracy class 2 and given as A-weighted. To measure sound power level Lw 10 microphones are distributed on an enveloping surface on the suction side of the fan under test (measuring set-up as per DIN 45635 T38). Measuring conditions ebm-papst products are measured under the following terms and conditions: - axial fans in the wall ring and without guard grille - Depending on the mounting situation, there can be deviations from the...
