EMI/EMC-standars in Canada and USA?

[Manfred W.]

Hi!

I kindly ask you for an anwer to the following question:
What are the limits that I have to stick to, concerning EMI/EMC (especially
conducted and radiated *emission*), when talking about industrial
equipment?
The device is three-phase-powered.
I need this information for Canada and USA, if you can provide it for other
countries too, you are welcome.

Kind regards

Manfred W.

 

Manfred:

If you go to:

http://www.access.gpo.gov/nara/cfr/waisidx_01/47cfr15_01.html

you can download the FCC Part 15 regulations for the USA. You need to
meet the Class A requirements which cover non-residential uses.
Industry Canada has similar requirements, a web search of "Industry
Canada" should give you some results. From your name I would guess you
are from Germany, sl you are familiar with the EU requirements.

Let us know if there is any further info you need.

Hi Manfred here below the limit according generic standard, but you
have to check if your products have specific standards (e.g. inverter
or other)

According to EN61000-6-3(Europe) (Electromagnetic compatibility - Part
6-3: Generic standard - : Emission standard for residential,
commercial and light industry. )
limits are
-radiated emission
30 to 230MHz 30dBuV/m
230 to 1000MHz 37dBuV/m

-conducted emission

0.15 to 0.50MHz Qp=66 to 56*dBuV Av=56 to 46*dBuV * Decreasing
linearly with the logarithm of the frequency
0.50 to 5MHz Qp=56dBuV Av=46dBuV
5 to 30MHz Qp=60dBuV Av=50dBuV

According to FCC §15.109 (US)
- radiated emission
30 to 88 MHz 39.1 dBuV/m
88 to 216MHz 43.5 dBuV/m
216 to 960MHz 46.5 dBuV/m
above 960MHz 49.5 dBuV/m

-conducted
0.15 to 0.50MHz Qp=79 dBuV Av=66dBuV
0.50 to 5MHz Qp=73dBuV Av=60dBuV
5 to 30MHz Qp=73dBuV Av=60dBuV
