A basic requirement for a realistic evaluation of crash-tests is suitable rating procedures. The rating procedures published up to now largely use the dummy loading values obtained from crash-tests. This paper deals with a rating procedure which gives the greatest possible consideration to all parameters having a bearing on the injury relevance and therefore considers not only dummy loading values but also to a large extent car-related data obtained by measuring and observation.

To illustrate the efficiency of the procedure presented here results of comparative head-on crash-tests with small cars and space cars are given as examples

In order to be able to ascertain the limits of the validity of the results obtained using the rating procedure a suitable validating procedure is basically essential. Besides this, quite a large quantity of type-specific accident data must be known for a selection of car models. The basic features of a validation procedure are described which can be used to convert these data into assessment quantities in such a way that they can be directly compared with the results of the crash-test rating procedure.
