Also, the EMI generated by the EUT should be within the limit of interference regulated by the country. To ensure the proper functioning of devices, an EMC test performs several sub-tests on the equipment under test ( EUT) to test the immunity of the victim device to survive in an environment of electromagnetic emission.

The devices used in our daily lives such as TVs, mobile phones, washing machines, ATMs, RFID tags, etc., all generate electromagnetic interference or can be damaged by interference generated by another device.

Types of EMCĪll devices have the potential to emit electromagnetic fields. EMC tests also determine how the device reacts to electromagnetic interference caused by another device. This interference must be within specific limits to avoid interference in the other devices present within the range.Īn EMC test identifies this electromagnetic interference generated by a device. The change of electrical current and voltage generates electromagnetic interference (EMI). This is because the motor draws more current, which causes a voltage drop. Sometimes we notice that the tube light is flickering when a water pump or motor device is on. It does not emit levels of EM energy that generate electromagnetic interference (EMI) in other devices in the vicinity.Įlectromagnetic interference (EMI) is the interference caused by one electrical or electronic device to another by the electromagnetic fields set up by its operation. EMC stands for Electromagnetic compatibility, which means that a device is compatible with (i.e., no interference is caused by) its electromagnetic (EM) environment.
