Actually the line conducted emissions limits in CFR47 section 15.107 has not been 450kHz to 30MHz for quite some time now (changed in 2005). It has been the same as CISPR (i.e. starting at 150kHz to 30MHz) since then.
Radiated emissions limits however, are different between CSIPR and CFR 47 15.109. The interesting thing about this however, is that 15.109(g)(4) states “(4) If the radiated emissions are measured to demonstrate compliance with the alternative standards in this paragraph, compliance must also be demonstrated with the conducted limits shown in §15.107(e).” I believe 15.107(e) was a commensurate statement in the line conducted section as the above statement is in the Radiated section. Problem is, since they went to the CISPR limits in 15.107 around 2005, and there is no longer a 15. 107(e) in the rules, so the note is meaningless.

Conducted Frequency limits for FCC are 450kHz to 30MHz. Conducted Frequency limits for CISPR are 150kHz to 30MHz. Now the FCC has said that it will accept the CISPR data, (47CFR15.33 I think) and Canada has said it will accept the CISPR testing data also. (I don’t remember what IC requirement states this?) I also remember that Canada said it will except FCC data (I think?)? I recall that if you tested to CE requirements you were basically covered in Canada IF you were testing at a FCC site also accepted in Canada.

ICES 003 has different limits to the FCC published limits - so be aware of that. For the test methods refer to the other emails in the thread. From: Ian McBurney [mailto:ian.mcbur...@allen-heath.com] Sent: Tuesday, September 17, 2013 9:35 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] USA & Canada rf emission test standards Dear Colleagues; I am trying to combine FCC 47 CFR part 15 and Canadian ICES-003:2012 radiated rf emission testing for a digital device that is an unintentional radiator. However; looking into the test standards for each country I am getting perplexed. It appears that for 47 CFR part 15 sub part B, the test standard for compliance is ANSI UL C63.4 2003 whereas for Canada it is the latest edition that is acceptable which I believe is the ANSI UL C63.4 2009. Similarly; if I was to apply the CISPR 22 method then CFR47 part 15 recognises the third edition of CISPR 22 and Canada applies the 6 edition 2008. Is there a common set of standards that can be applied for radiated & conducted rf emission measurements that is acceptable in both the USA & Canada? I am carrying out measurements from 30MHz to 2GHz to class B limits. Many thanks in advance. Ian McBurney Design & Compliance Engineer. Allen & Heath Ltd. Kernick Industrial Estate, Penryn, Cornwall.
