Test procedure of fan

Test procedure of fan

1. Current: The current is measured after 3 minutes of continuous rotation.
 
2. Speed: Rate is measured after 3 minutes of continuous rotation.
 
3. Starting Voltage: Voltage that can start fan operation after opening switch ON
 
4. Input power: Input power is measured after 3 minutes of continuous rotation.
 
5. Lock-in current: the fan that can lock the machine. Lock-in current in fresh air for 3 minutes.
 
6. The measurement of air flow and pressure data is based on "AMCA Standard" or DIN24163 Rule. The measurement of air flow and pressure data is carried out in double pressure chamber, and the pressure data on each side of pressure chamber should be measured.
 
7. Noise Standard: Noise Standard Test refers to DIN45635 Standard. Measurements are carried out in a sound insulation room. Microphones are placed one meter above the fan.
