scope:

This Standard defines the electromagnetic compatibility "EMC" (immunity and Interference) performance levels, testing methods, and performance criteria for lighting products in a frequency range from 0 to 400 GHz.

This Standard applies to lighting products intended to be directly connected to the mains (up to 600V), DC (up to 250VDC), battery-operated, or to a non-public, low voltage power distribution system.

In the United States, high-frequency emissions are regulated by the Federal Communications Commission (FCC) 47 CFR Parts 15 and 18.

For a Standard on Inrush Currents, see NEMA 410 Performance Testing for Lighting Controls and Switching Devices with Electronic Drivers and Discharge Ballasts.
