The objective of the study was to develop standards by which the safety of automobile doors could be determined. Door systems of late model automobiles, trucks, and multi-purpose vehicles were defined, described and classified into groups. Several of the most common types of accidents were considered, namely, two-car collisions and one-car accidents resulting in obstacle impact, or either roll-over or end-over-end flipover. A sample was obtained of about 1000 actual accidents that occurred in October, 1967, in Minnesota and Texas. In these accidents, 288 occupants from a total of 1,367, received injuries related to the adjacent door. The sample of data on automobiles involved in collision and roll-over accidents was classified, reduced and analyzed in order to obtain detailed data on factors relevant to door performance. A statistical analysis was then conducted to determine the distribution of door loads and their relation to door system failures. Full-scale laboratory tests were devised and conducted to obtain data on door system performance under carefully controlled crash simulation conditions. Evaluation of all data led to a number of documented conclusions and a set of recommendations for door performance safety standards. Because it was found that a vehicle's total weight influences the collision loads sustained on its doors, this factor was included in the recommended performance standards.
