Side Impact Test

Method for Side Impact Test

  • Vertical side impact by the moveable wall with speed of 55km/h that is 5km/h faster than the test speed of 50km/h by the law
  • Equipment of dummy for side impact in driver seat
  • Installation of sensor to measure the impact in head, chest, etc of dummy
  • Dummy for Side Impact : It is a male dummy called EuroSID-2 with height of 178cm and weight of 72kg developed in Europe.
  • It revives the situation that the moving wall composing the front side figure and feature of a general sedan vehicle (aluminum honeycomb that is the material for bumping the collision is attached onto the front colliding part) collide vertically to the broadside of a vehicle.

Method to Read Result of Side Impact Test

  1. Injury Scale
  • Calculates the point by measuring the impact on head, chest, abdomen, pelvis, etc of passengers in front seat.
    ※ Severe Injury (AIS3): It refers to the Level 3 of Abbreviated Injury Scale of USA. Namely, it refers to the injury of over 1~6 hour of unconsciousness, depressed fracture, contusion of heart, 2~3 rib fractures (existence of blood or pneumothorax)

  • Measurement result is divided into 5 Levels and highest scale and lowest scale is indicated with 5 stars and 1 star respectively.
Injury Level Impact of Passenger in Front Seat
★★★★★ Over 13.00
★★★★ Over 9.00 ~ Under 13.00
★★★ Over 5.00 ~ Under 9.00
★★ Over 2.00 ~ Under 5.00
Under 2.00
  • Injury value for each body part is indicated with 4 colors

    Injury value for each body part is indicated with 4 colors, Green Good, Yellow Acceptable, Orange Marginal, Red Poor

Protection for each body part (Moveable wall side impact with speed of 55km/h)
Section Passenger Protection Good Acceptable Marginal Poor
Color Green Yellow Orange Red
Head Injury Criterion Under 500 Over 500 Under 1,000 Over 1.000 Under 1,500 Over 1,500
Chest Compression(mm) Under 25 Over 25 Under 42 Over 42 Under 52 Over 52
Compression Speed(m/s) Under 0.6 Over 0.6 Under 1.0 Over 1.0 Under 1.3 Over 1.3
Abdominal Load(kN) Under 1.2 Over 1.2 Under 2.5 Over 2.5 Under 3.5 Over 3.5
Pubic Load(kN) Under 3.0 Over 3.0 Under 6.0 Over 6.0 Under 8.0 Over 8.0
Section Injury Value Point Possibility of Severe Injury (AIS3)
Head Head Injury Level 0~4 point 5~20%
Chest* Chest Compression 0~4 point 5~30%
Chest Compression Speed 0~4 point 5~50%
Abdomen Abdominal Load 0~4 point Rupture in Abdomen (0 point)
Pelvis Pubic Load 0~4 point Pubic Fracture (0 point)
Total 0~16 point** 0~16 point(5~50%)
* Adopt lower point for the injury value of chest
** Perfect Score (16 points) refers to the possibility of severe injury in head and chest under 5% and no rupture in abdomen & no pubic fracture.

2. Door-Opening at the Moment of Impact
  • Check the door-opening at the moment of impact since passenger may spring out to the outside when door opens at the moment of impact.
    No door-opening at the moment of impactDoor-opening at the moment of impact

3. Easiness in Door-Opening after Impact
  • Measure the amount of strength consumed in manual door-opening from the outside after impact since passenger may easily be rescued from the outside or come outside by himself when door opens easily after impact.
    Manual door-opening after impact No manual door-opening after impact

4. Gas Leakage after Impact
  • Check the gas leakage after impact since fire may start with the engine heat when there is gas leakage after impact
    No gas leakageGas leakage
