New Crash Tests Required by November 2007

October 23rd, 2007

NHTSA modified Part 571 in September, incorporating a dynamic pole test and the enhancingthe moving deformable barrier test for FMVSS 214 side impact testing. The final rule will be effective November 13, 2007.

This final rule incorporates a dynamic pole test into FMVSS 214, ‘‘Side impact protection.’’ To meet the test, vehicle manufacturers will need to assure head and improved chest protection in side crashes. It will lead to the installation of new technologies, such as side curtain air bags and torso side air bags, which are capable of improving head and thorax protection to occupants of vehicles that crash into poles and trees and vehicles that are laterally struck by a higher-riding vehicle. The side air bag systems installed to meet the requirements of this final rule will also reduce fatalities and injuries caused by partial ejections through side windows.

Vehicles will be tested with two new, scientifically advanced test dummies representing a wide range of occupants, from mid-size males to small females. A test dummy known as the ES–2re will represent mid-size adult male occupants. A test dummy known as the SID–IIs will represent smaller stature occupants. The SID–IIs is the size of a 5th percentile adult female.

This final rule also enhances FMVSS 214’s moving deformable barrier (MDB) test. The current 50th percentile male dummy in the front seat of tested vehicles will be replaced with the more biofidelic ES–2re. In the rear seat, the new 5th percentile female SID–IIs dummy will be used, thus improving protection to a greater segment of occupants seated in rear seating positions.
