RE: FCC exemptions
Several years ago my company exercised this exemption because our equipment at that time was extremely large and somewhat difficult to stage. More recently, we have elected to test and verify to FCC or CISPR regulations. One word of caution. The exemption by the FCC may still be valid, but as I understand it, this merely eliminates the need for testing. It does not eliminate the responsibly to correct subsequent EMI problems.

Re: FCC exemptions
Part 18 is to be used by ISM equipment that intentionally generates RF energy for a designed purpose such as an arc-welder, MRI medical device, or an induction heater. Equipment that intentionally generates RF energy to be used within the device such as for the purpose of moving data along a bus are covered by Part 15 (unintentional radiators). === === ron_pick...@hypercom.com on 01/12/99 04:25:27 PM Please respond to ron_pick...@hypercom.com To: emc-p...@ieee.org mvald...@netvision.net.il cc:(bcc: Robert E.

Anyway, it would seem that your "industrial product" should comply with Part 18, not Part 15. Anyone out there with more experience in this area than I want to comment further?

RE: FCC exemptions
Moshe, The FCC provides a brief explanation of this "test equipment" exemption and other exemptions in OET bulletin 62, page 7 (download from http://www.fcc.gov/oet/info/documents/bulletins/) The key is that the equipment is used exclusively as test equipment in environments where interference is less likely to cause communication interference, and is still subject to the rule that equipment operation must stop if it causes harmful interference. If you use the exemption, you may expect trouble if the product actually performs other functions or if it is used in a location where the interference generated would cause problems.
