These are primarily all appliance items. All we need to do is be classified as an appliance somehow... https://www.compliancegate.com/fcc-part-15-product-list/#Products_Exempted_from_FCC_Part_15
Products Exempted from FCC Part 15
FCC Part 15 covers electronic products that are classified as an intentional or unintentional radiator. It applies to most consumer electronics and electrical equipment with a CPU operating at 9kHz or higher frequency. That said, some electronic products are exempt. Here are some exemptions for your reference:
- Refrigerators
- Stoves
- Washing machines
- Water heaters
- Rug cleaners
- Dishwashers
- Air conditioners
- Fan heaters
Pondering on it, it's kind of funny. What made those particular 8 items be granted FCC approval to cause as much interference as you want. And why specifically rug cleaners of all things?
It's funny.
And why specifically rug cleaners of all things?
With a new president coming to the Oval Office they are running the heck out of the rug cleaning machines and need to ward off FCC noise complaints.
May be that those in the list don't cause adverse enough interference to be concerned about. I have never heard AM radio noise from any of those things.
The only thing on that list that *may* cause some close up interference is an air conditioner but I have held a radio right beside the outside air conditioner and no noise was heard on the radio. A heater, refrigerator, stove do not cause interference.
@mark Well, see that just makes the whole thing odder! For what reason where such devices ruled to be exempt from any part 15 restrictions in the first place - expecially, as you say, they dont even cause interference.
The FCC actually took action to exempt them. I'm sure there's a reasonable purpose behind it, but at face value it's peculiar.
@richpowers I would think that the interference the FCC would be more concerned with is RF interference. Maybe there is some other kind of interference that these things listed could cause...don't know, just thinking, maybe like magnetic fields, something along those lines.
But rug cleaners??
@mark Don't know, but don't think so. It doesn't add up (at least not to me). I didn't even know automobiles were exempt from Part 15 regulations until Telsa decided to leave AM radio out. Maybe the reasoning is all indirectly interconnected with rug cleaners and the like somehow...
I haven't grasped what makes certain devices such as cars and the appliances previously listed ad specifically exempt. Its odd.
Kind of reminds me of a entirely different FCC oddity.. I always wondered what ever happened to influence the FCC to find it neccessary to officially explain (in regard to part 15 tunnel radio systems) that "a oil tanker is not a tunnel", only something totally surrounded by earth except for the openings were tunnels.. I know it must have been related to "Tunnel Systems USA" who had a franchise going on at the time.. All I can figure is that someone, somewhere was broadcasting from inside a oil tank to avoid the regular part 15 emission limits (tunnel radio is to an extent exempt from part 15 too)
