The National Road and Traffic Research Institute's (VTI) technical resources for collision tests are in general compatible with those of the American auto-industry. The most marked difference is the calibration of test dummies where VTI totally lacks resources but where GM and Ford have invested large amounts. The calibration equipment refers to head, neck, chest and legs/knees. For heads they use fall tests, the other calibration 'stations' are swing weights. GM's calibration equipment was easy to work with and well planned. Small details in the design separated GM from Ford. GM and Ford have each about 10 persons whose only jobs are calibrating and reparing dummies. VTI's lack of equipment for calibrating dummies results in a reduced capability to perform tests in accordance with international rules and regulations. It also becomes more difficult and sometimes even impossible to compare our test results with others. The dummies are an important link in a measurement system where all other equipment is carefully calibrated. 'No chain is stronger than its weakest link' which in VTI's case refers to the dummies.
