EUROSID is the side impact dummy that has been designed and has now been almost completely developed by a group of European research laboratories working together under the auspices of the European Experimental Vehicles Committee (EEVC). It represents a bringing together of components and ideas from the three experimental sided impact dummies sponsored by the EEC1 as part of their Biomechanics Programme. These were produced by APR (Peugeot-Renault), ONSER, and MIRA. This paper describes the evolution of the EUROSID dummy and discusses the advances in biofidelity, the responses of its various components to impact, and the types of measurements it can record.

Following the European Experimental Vehicles Committee's definitions, the mobile barrier frame was built by several partners and rigid polyurethane foam selected as the material for the front deformable face. A validation process consisted of different tests distributed among ONSER, BASt, and TRRL. ONSER, UTAC, and TRRL conducted impact tests on individual blocks, total tests against a dynamometric wall, and lateral impact tests against the Renault 14 as struck cars. The validation was completed by performing barrier-to-car tests at the BASt facility according to the proposed EEVC impact test procedure. The basis for comparison was given by car/car tests under the same conditions and with cars of the same type. These cars were the Golf and Daimler Benz (W 123 series). Results from this test series show the barrier face has a very useful crash simulation fidelity and repeatability

In the United States as well as in Europe standard test procedures for car occupants protection in side impact accidents are discussed. These procedures correspond to a new approach for side impact protection; both are based on full scale test, but with different parameters for its definition. A test procedure is necessarely a compromise between a fidelic representation of accidents and simplicity for a good repeatability. As the application of a procedure would improve the protection offered to car occupants in real accidents, it seems important to evaluate the benefits which could be expected from its use by comparison of the procedure parameters with the description of the accidents.
