Amund, The 4th Edition differs from the 3rd Edition plus Amendments 1 and 2 by making changes in the telecommunication port conducted emissions tests. The LCL values change for the ISNs, along with other changes. Labs will be needing to have their ISNs re-built or replaced. Also, the 10 dB relaxation of the limits for class B devices from 6 MHz to 30 MHz for emissions from wanted signals is deleted.
You'll need to log on to the IEC web page and buy a copy of the new standard for the full details.
