Professor Younghan Youn presented an evaluation of WorldSID and ES-2 50th male pole side impact test results (PSI-07-04). These tests were part of a WorldSID and PSI joint research program conducted by Hyundai Motor Company and KATRI.

Professor Youn explained that car-to-car accidents are the major source of side impact fatalities in South Korea. UN R95 is applied in South Korea, but a significant proportion of fatalities are due to head injury. UN R95 cannot guarantee head protection. A reduction in head injury fatalities is a benefit that will come from a pole side impact regulation.
WorldSID and ES-2 50th males indicated similar AIS 3+ abdominal and pelvic injury risks in 32 km/h oblique pole side impact tests of the same vehicle model. However, the WorldSID 50th predicted a substantially higher head injury risk and ES-2 indicated a higher thorax injury risk. The WorldSID test was done using the ISO WorldSID seating procedure (draft) and the ES-2 test was done using the EuroNCAP pole side impact seating procedure.

Ms Tylko suggested the WorldSID 50th male may possibly have impacted a seam or sub-optimal portion of the curtain airbag, given the very high head injury risk recorded.
