Humidity reportedly causes a scatter of maximum acceleration in a dynamic certification test using a Transport Research Laboratory (TRL) legform impactor according to the European Enhanced Vehicle-safety Committee (EEVC)/WG17 method. The possibility was considered that humidity might affect the injury criteria for the TRL legform impactor to bumper impact test. To clarify the differences in the maximum acceleration of the impactor in different humidity conditions, the legform impactor to bumper impact tests were conducted in two different humidity conditions (30%RH and 60%RH) using two sedan cars. Furthermore, numerical simulation of the legform impactor to bumper impact test were conducted in two different humidity conditions using one sedan car finite element (FE) model. In the legform impactor to bumper impact tests and the numerical simulation, the measured injury criteria used were the same in the two humidity conditions. The results indicated that the humidity condition does not affect all injury criteria in the legform impactor to bumper impact test.
