any enforcement measures related to powerline communication systems). The

first such report is due on 31 December 2005.

8. This Recommendation is addressed to the Member States.

Done at Brussels, 6 April 2005 for the Commission, Viviane REDING, Member of

the Commission.

At the Cenélec, the PLC guidelines are adhered to by the following technical

committees (TC) and subcommittees (SC):

•

TC 205, “Home and building electronic systems (HBES)”;

•

SC 205 A, “Main communicating systems”;

•

TC 210, “Electromagnetic compatibility (EMC),” CISPR mirror.

The mission of the SC 205, a “product” subcommittee, is to “prepare harmo-

nized international standards for communication systems using low voltage electric

lines or the building wiring as a transmission medium and frequencies greater than 3

kHz and up to 30 MHz. This task includes the allocation of frequency bands to

transmit the signal over the low voltage network.”

To comply with the IEC’s nonduplication of work principle, the work on the

product international standard is more or less pending in this subcommittee.
