Project: Side Impact Research

Reference: S090A/VF

The objective is to determine if controlled engineering changes made to vehicles would be correctly assessed by the Parila Test procedure and whether the Partial Test could be used to give reliable information to an approval authority regarding the need to request a new full scale test.


The work in this project over a number of years lead to the planned introduction of side impact testing in EU type approval testing for new types of cars. Although this project has ended a new project S095A/VF is continuing development work.

Summary of results

  1. This project concluded that the Partial Test procedure, as defined in the Directive, is not sufficiently precisely defined and a number of different interpretations are possible. Comparison between the full scale test results and those from partial tests to the same structures showed a very poor correlation strongly indicating that the guidance that may be obtained from such testing would not accurately predict changes in injury risk and would mislead approved authorities in their decision making process regarding the need for vehicle retesting following minor trim or model changes.
