UL 943 does include tests for resistance to environmental noise using a
10 - 450 MHz signal source.
Unless the GFCI includes active electronics, it's not obvious what this
test is for. It should be quite clear that if there is an immunity
issue, it is far more likely to occur between 2.4 kHz and, say, 200 kHz.
