The tasks of EEVC Working Group 13 are aimed at the improved protection of car occupants in side impacts. Specifically, EEVC WG13 has been concentrating on three main tasks; the development of an interior headform impact test procedure, an improved specification for the Mobile Deformable Barrier used in the EEVC Side Impact Test Procedure and contributions to the IHRA activities on the development of the next generation side impact test procedures. This report describes progress on these three topics.
