A couple of things 1 Never put a lot of confidence in statements like interference is unlikely.
2 Exemption from having a specific technical limit or exemption from FCC authorization, does not mean exemption from compliance. Industrial digital devices are subject to the general rules of 15.5 which states they are not to cause interference, and if they do they are to stop operating. Industrial devices also have a specific interference mitigation process they may have to go through if they are found to cause interference. 3 The exemption for industrial equipment under 15.103 applies ONLY to test equipment. Many, if not all, Industrial devices do have technical limits in Part 18. They also may have general emissions limits outside the actual operating frequencies of the device in that rule part. While these limits may be more relaxed than part 15, they none the less do exist. 4 If the "industrial machine" is not a piece of test equipment, is not an appliance, is not a transportation vehicle or an electronic or power control system or the like, exemption under 15.103 cannot be applied. Also most industrial devices are likely to be subject to the specific limits in Part 18.

I am working on the first Industrial Machine of my career so I could use some advice and clarification regarding the requirements for FCC emissions. I have been told by many that in North America, Industrial Equipment does not have to be tested, verified, or anything for FCC by the manufacturer of the equipment. Is this true? I was told that interference is unlikely, even if the equipment exceeds the FCC emissions limits. Meeting the FCC limits is recommended, and voluntary, but not required. True? On the other hand, Europe is not so. If EE equipment goes to Europe, it has to pass the EN 55011 emissions test as well as the immunity tests. Is that correct? Any additional information that would be helpful to me would be appreciated.
