The standardization of the BioRID‐II has been discussed at the UN ECE/WP29/GRSP/GTR7, and setting‐up this standardization has been deemed of utmost importance. One of the more important points that has been underscored is that the repeatability and reproducibility of BioRID‐II when conducting sled testing, as reported by several institutes, have not been very reliable. In this study, newly proposed calibration test methods for the BioRID‐II were performed. The comparison with sled test results was performed and the validity of the calibration test method was analyzed. Moreover, the calibration test method that required the dynamic responses of the dummy was also discussed. As a result, for the suggested calibration tests based on this study, the BioRID‐II showed good repeatability and reproducibility. And, if the calibration test for keeping good repeatability and reproducibility is selected based on this study, the calibration test with headrest (heavy probe) will be proposed because the peak and dummy's variation occurred most notably.
