Side impact barrier~Development and evaluation

The desire for improved transport safety led to the introduction of ECE Regulation 95 and EU Directive 96/27/EC for the protection of vehicle occupants against lateral collision. The Regulation includes a dynamic full-scale impact of a mobile deformable barrier (MDB) into the side of the target vehicle. The MDB comprises a trolley with a deformable face, currently defined by dimensions, force-deflection and energy dissipation requirements.
Some vehicle manufacturers have experienced difficulties when testing due to what is now recognized as the differing behavior of barrier faces that have been certified to the dynamic performance requirements set out in the Directive and the Regulation. Following an evaluation of all the MDB faces available to the performance specification, the European Enhanced Vehicle-safety Committee (EEVC) recommended that a design specification should be developed for the MDB face so as to improve consistency, repeatability and reproducibility. This recommendation was supported by the EC and Member States and a program of work was devised to produce a design specification and undertaken an extensive test program to validate barrier faces built to that specification.
