Variability of Results of the Same Test Conducted in Three Different Laboratories
Published January 01, 1989 by National Highway Traffic Safety Administration in United States
Passenger protection in a side collision was investigated in numerous tests in different laboratories. As for other studies and researches involving an international cooperation, results of tests are compared. The aim of this presentation is to investigate the validity of the result exchanges and in other words to look at the reproducibility of the same test conducted in different laboratories.
INRETS, BASt and TRRL decided to conduct the same test in the same conditions and to compare the results. As these three laboratories are involved in side impact protection research, this study was based on a full-sacle side impact test against a Ford Fiesta according to ERGA conditions.
As a result of the investigation, it can be stated that some differences occurred because of the accumulation of differences between the technical parameters required for the test performance.
Nevertheless, the main conclusion is that the protection criteria were not exceeded in the three laboratories.
