The paper reviews the cadaver data base that has been used to design and develop the European side impact dummy. The production dummy called EUROSID-1 is briefly described. The quality and usefulness of the available cadaver data is reviewed and ranked in terms of its importance in determining the biofidelity response targets for a side impact dummy. Brief comparisons and comments are made on the proposed ISO TC22/SC12/WG5 requirements and the performance of EUROSID-1
