| Abstract(in English) | Since the past ten years, CISPR has continuously taken up "the rationalization of the test method of EMI (to radiated disturbance)" as the most important problem, however, it has remained yet unsolved. That is, in the EMC Symposium held at Zurich Switzerland in 1991, IBM officially announced basing on the results of comparative tests by the 3-m method carried out at 34 excellent sites chosen out of all over the world, and disclosed that the values of EMI field strength obtained exhibit a dispersion of 10 dB or so. Germany pointed out in Beijin Conference 1994, the inadequacy of CISPR test method on actual data collected at 6 sites, giving a dispersion, greater than 10 dB. In the latest Durban Conference 1995, each country was requested again to cooperate in theoretical studies on problems relating to EMC test site and method. This paper coping with these problems explains theoretically that the CISPR recommended sites including the one by 3-m method give uncertain correlation factor that is liable to generate an error exceeding 10 dB, and also shows that this problem is solved only through making a free space of the test site and of the limits for radiated disturbance. |
