In view of impending changes in the British Standard concerned with ignition interference, to conform with the recent International Agreement (E.C.E. Regulation No. 10) and the probable corresponding amendment to the United Kingdom legislation, a series of road-side measurements of ignition interference radiation has been made on more than 10,000 vehicles.
From the known suppression arrangements currently used on the vehicles measured, the results have been analysed as to their efficacy in relation to present United Kingdom legislation and the E.C.E. International Regulation; reference is also made to the SAE Standard J.551a and b.
The effects of multisource ignition interference resulting from areas of high density traffic on the reception of VHF frequency-modulated radio and VHF positive-modulation TV signals are described.
