Departure of some old 'favourites'
By J. M. Woodgate B.Sc.(Eng.) C.Eng. MIET SMIEEE FAES Hon FInstSCE MIOA
As a result of the publication of CISPR 32 and CISPR 35, the superseded standards are being withdrawn. The withdrawal of the emission standard CISPR 13 in March 2017 possibly escaped notice, because the withdrawal document was circulated to national standards committees in 2012, intending to give manufacturers time to react. The same applies to the emission standard CISPR 22, which was extensively referred to normatively in other standards. Now we have been notified that the immunity standards CISPR 20 and CISPR 24 will be withdrawn in July 2020.
Whereas CISPR 20, CISPR 22 and CISPR 24 are quite recent upstarts in comparison, concerned with these computer things, CISPR 13, being originally concerned with conducted and radiated emissions from radio and TV broadcast receivers goes way back, to IEC (60)106, at a time when IEC TC12 was responsible for the standard, in MCMLXXIV. Later, the work was transferred to a new committee, CISPR/E, which added the immunity standard CISPR 20 and much later merged with CISPR/G (responsible for CISPR 22 and CISPR 24) to form CISPR/I.
New kids on the block
There are quite a few of these, so a table is called for. Most of this information is on the public part of the IEC web site, www.iec.ch, but you need time and patience to explore.
