Abstract (in Japanese) (See Japanese page) 
(in English) Regarding EMC measurement for in-vehicle unit at different test sites, a high correlation between different test sites is necessary. In order to confirm a degree of correlation, Annex J is added to CISPR 25 (Edition 4, 2016-10), the international standard related to EMC measurement for in-vehicle unit. Measurement based on this standard was made at different test laboratories. As a result, all test laboratories observed data different from the reference data shown in CISPR 25 in the frequency range from 10 MHz to 30 MHz. After the investigation into the cause of the different data, it was found that the difference between a test setup used at test laboratories and the model setup for reference data was a major cause. This investigation will be described in this paper.
