A Survey Concerning the Quality of Part 572 Hybrid II Dummies as Measuring Instruments for Crash Testing

Two Part 572 Hybrid II dummies, of different manufacture, were subjected to a programme of testing work in order to evaluate deviation factors which can be accorded to various injury criteria and other measurements determined using this type of dummy. The programme at two testing facilities consisted of a total of ten series of dummy component calibration tests according to CFR49 - Part 572 and four series of six nominally identical system sled tests. On the basis of the work carried out deviation factors within a thirty per cent band could be accorded to the important injury criteria and measurements.
