CE certification . Let's take a look at the details.

In terms of detection items, there are external disturbance experiments, power port immunity detection, chassis port immunity detection, I/O port immunity detection, ground port immunity detection, and other precautions, such as battery rules that need attention. Let's take the chassis port immunity test as an example to understand the detail of the detection standard.

Chassis port immunity detection is divided into radio frequency electromagnetic field radiation, digital wireless telephone electromagnetic field radiation, electrostatic discharge, power frequency magnetic field, pulse magnetic field five detection items. In the detection of electrostatic discharge, if it is in contact with air discharge, the difference cannot exceed 6kV, if it is discharged directly in the air, the difference cannot exceed 8kV, that is, the revolution of the motor must be maintained in a stable range. When doing the test, the temperature of the laboratory should be 15 to 30 degrees Celsius, the humidity should be 30% to 70%, and the air pressure should be 90 kappa to 100 kappa. Before the test, the sample should be checked whether the wiring is correct, and the pulse magnetic field power supply of the instrument and the sample should not be connected.

The above is the ce certification body on the CE certification testing standards of electromagnetic compatibility testing detailed introduction, I hope to help you, if you need to reprint, please indicate the source, thank you!
