The FCC has the authority to mandate immunity for Part-15 devices, but has declined to do so. The exception is for consumer telephones and other telephone equipment under FCC Part-68 rules. But in general, noise immunity is practically unregulated in the USA.
The FCC expects industry to handle immunity problems (either by design or by technical support) and wants the consumer to understand that immunity problems are not a matter for FCC involvement. For example, here is the Class A (and old Class B) warning label required under Part-15 section 15.19: "This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation." Only noise emission is regulated under Part-15. You may use CISPR-22 emission limits with ANSI C63.4 test procedures. Note that the FCC expects conducted emissions to be measured at 115 VAC, 60 Hz. Since the FCC is changing their procedures every other month or so, you should check their web page for current information (and download the rules - officially known as 47 CFR Part 15 and Part 2) at: http://www.fcc.gov Regards, Eric Lifsey Compliance Engineer/Manager National Instruments "Brian Harlowe" <bharl...@vgscientific.com> on 07/02/98 11:49:41 AM Please respond to "Brian Harlowe" <bharl...@vgscientific.com> To: emc-p...@ieee.org cc: (bcc: Eric Lifsey/AUS/NIC) Subject: Ce versus FCC Can someone out there tell a poor Englishman the basic differences between the requirements of the FCC rules and the requirements to comply with the EEC emc directive. i.e. Do you have to do immunity testing and ESD tests to comply with the FCC rules that sort of thing.
