Abstract(in English) The nowly developed radiowave darkroom or open-free site confronts a technical issue i.e.,the correlation with the CISPR recommended standard site(whose measuring distance is 3m,10m or 30m).The investigation of the correlation issue has indicated that the mutual conversion between CISPR-type sites with different distances is actually impossible and that some conversion error exceeding 5~10 dB is included even among CISPR recommended standar d sites.And it has become more and more evident that only one remedy to this issue is ″making a free space of thd site″.A conve rsion factor table has been prepared through simulation in the test conditions,since defining ″correlation factor in relative to the free space″ is indispensable for rationalization of conversion method.In addition to this,an overall comparison with CISPR recommended type has been made to show its practicability of the free space type.
