CISPR is acronym for the French words for the International Special Committee on Radio Interference.  “Comité International Spécial des Perturbations Radioélectiques”

CISPR is a special committee of the International Electrotechnical Committee (IEC).

CISPR is organized into a number of subcommittees.  These cover a variety of subjects.

CISPR SC I, Electromagnetic compatibility of information technology equipment, multimedia equipment and receivers, deals with product family standards for the subject equipment.  SC I was formed in 2001 by merging the old SC E (Broadcast receivers) and SC G (Information Technology Equipment).  This was brought about by the convergence of the two technologies in the form of digital television receivers.

Subcommittees may have Working Groups or Maintenance Teams under them.  Under IEC guidelines, Working Groups are formed for the purpose of writing new standards and Maintenance Teams are formed for the purpose of maintaining existing standards.

We haven’t paid much attention to this distinction in the past in CISPR SC I.  We created CISPR 32 under WG2 and CISPR 35 under WG4, but these WGs also maintained the older CISPR 22 and CISPR 24 standards.  We are paying attention to the distinctions now.

Effective at the CISPR Plenary Meeting in October 2017 in Vladivostok, Russian Federation WG2 and WG4 were dissolved and replaced by MT7 and MT8.  MT7 is responsible for maintenance of CISPR 32 and MT8 is responsible for maintenance of CISPR 35.  National committees were invited to name experts to these MTs and the leadership is the same as was in place for the WGs.  These two MTs are actively working on amendments to CISPR 32 and CISPR 35 and next meet the end of February / beginning of March in Milan, Italy.

CISPR SC I is presently looking for National Committees to name experts to a new MT, MT9.  It was found that CISPR TR 29 needs updating and a new MT is being formed to do this work.  As the period for National Committees to name experts to MT9 is still open not much more can be said about it at this time.  If you have an interest in this Technical Report, please feel free to contact me at the address below and I’ll put you in contact with the head of the US TAG for CISPR SC I.  One of the items of business at the next CISPR SC I Plenary meeting (in October in Busan, South Korea) will be to name a convenor for this new MT.
