What is a Side impact? And what parameters need to be recorded?

NHTSA's side-impact test represents a vehicle struck on the left side by a 3,015-pound car traveling at 38.5 mph. 
This represents,what could happen if you were hit on the side at an intersection. Individual side-impact star-rating scores are assigned to the driver and left-rear passenger.
Parameters
For pre-2011 models, only a chest-injury measure dictated the score. 
For 2011 and later models, the score factors in head, chest, abdomen, and pelvis data for the driver and injury to the head and pelvis for the rear-seat passenger.

The IIHS side-impact test is comparatively more severe than NHTSA's. Thestriking barrier at 3,300 pounds is heavier.Also, the IIHS barrier strikes higher up on the tested vehicle to simulate a car being hit on the side at 90 degrees by a typical-height SUV or truck. 
Parameters
The IIHS bases its scores on head, neck, chest, abdomen, pelvis, and leg injury.
