EMC test is defined as electromagnetic compatibility test, and LED lamp electromagnetic compatibility (EMC) refers to that LED lamps operating in their electromagnetic environment will not cause unbearable electromagnetic interference to any equipment in their environment. LED lamp EMC includes two requirements: the electromagnetic interference of LED lamps to the environment during normal operation cannot exceed a certain limit value; On the other hand, it refers to electromagnetic interference to the environment during normal operation; LED appliances have a certain degree of immunity to electromagnetic interference existing in the environment, that is, electromagnetic sensitivity.
Applicable EMC standards for lighting products:
EN55015:2006+A1:2007
Limits and methods of measurement for radio disturbance characteristics of electrical lighting and similar equipment
EN61547:1995+A1:2000

Electromagnetic compatibility limit Harmonic current emission limit (equipment input current ≤ 16A per phase)
EN61000-3-3:2008
Limitations of electromagnetic compatibility limits on voltage changes, voltage fluctuations, and flickers in public low-voltage power supply systems for equipment with a rated current of ≤ 16A per phase and unconditional access
