Yeah it is pretty rigorous. Don't know all the details but it is pretty hard to do anything without EMI lab qualification. But projects, like those in Silicon Chip, Jaycar seem exempt. Also it is a complaints based system, I doubt much of what is imported from China would actually qualify. Even the new Waratah trains if you drive by a train line seem to heavily interfere with AM broadcasts, but they still run. It's probably their 3 phase inverter drives, harmonics right in the AM band.
