I would advise scanning radiated emissions to 1000 MHz as well. I wouldn't put anyone off from doing that, BUT the court case was about safety issues; the EMC case was not brought to court. This is because it implied that the EN was defective, and the British Government would have had to refer that to the Commission under Article 8 of the EMC Directive. Public interest considerations indicated that this should not be pursued. A new edition of EN 55014-1 is due to be published at about the end of this year. But it still doesn't cover emissions up to 1 GHz; that is still being studied. > >One other item, EN 50366 (Household and similar electrical appliances - >Electromagnetic fields) which falls under the Low Voltage Directive now >requires the measurement of human exposure to electromagnetic fields >for household and similar electrical appliances.
