NHTSA and IIHS Crash Test Scores Explained

NHTSA - 2013 Ford Fusion Sedan & Hybrid - front / side / pole crash tests



Nearly 100 years ago, car passengers face the risk of death, even in a minor by the standards of today fender bender car safety has evolved so much in recent times that it is possible escape minor or no injury at all of 80 km h 50 mph frontal crash over the past five years, some independent organizations have begun to perform well established crash tests whose results have become a very important part in the purchase decision of almost all new car customers This article will attempt to explain the criteria by which every American crash test organization achieves its results.
Older crash tests sponsored by the government in the United States were first conducted by the National Highway Safety Association NHTSA traffic in 1978 a division of the Department of Transportation of the United States, the NHTSA Association began a series of trials that are now designated as the new car assessment program NCAP 5 stars or government assessments the second American association to conduct large-scale crash test was the insurance Institute for Highway safety IIHS, which is an organization sponsored by the insurance companies, they started demolition of the cars in the name of science and safety in 1995.
Although both organizations are crash test cars for a similar reason, everyone has a different procedure to obtain the desired results carry two front and side crash tests, although differently conduced Also, the IIHS evaluates seat and supports -tête in rear crashes, bumper collisions at low speeds, while the NHTSA also has a rollover crash test.
Not all cars on the market is tested, but the vehicles being hit deliberately into a wall are generally chosen following a customer popularity factor Now we'll take a look at how each crash test is performed, so that customers car everywhere should understand the reasoning behind each front crash test results NHTSA As we mentioned earlier, the NHTSA and IIHS have their way of doing tests first look at a NHTSA in the frontal test, both dummies of male average size of crash tests are placed in the driver and the front passenger seat and are secured by the mandatory safety belt car, the vehicle is then front crashed into a rigid barrier at a speed of 35 mph 56 km h this speed is trying to recreate the impact of two vehicles weighed similarly enter each other front collision saw ess mentioned above.



The force imposed on high-tech mannequins is then measured and NHTSA dudes give the car a star based on the risk of serious injuries each dummie, expressed in percentages By the way, for serious injury NHTSA means injury that requires immediate hospitalization and may be life threatening, so a broken nail doesn t count the ratings used by NHTSA doing everything look like a game of Russian roulette, but here they are anyway.
5 stars means 10 or less chance of serious injury 20.11 4 stars signifying risk of serious injury which means 3 stars 21-35 risk of serious injury means 2 stars 36-45 risk of serious injury 1 star means 46 or more chance of injury severe frontal crash test organization IIHS IIHS performs two slightly different frontal tests in the first, the vehicle strikes a deformable barrier offset manner, which means that one end of the driver is hit test is performed at 40 mph 64 km h and about 40 percent of the front end of the car impacts with the deformable wall of the second, called small overlap preliminary test, only 25 percent of the vehicle front portion faces a non-deformable barrier 40mph 64 km h.
Trying to be even more special, the IIHS doesn t use stars to classify the vehicle tested Instead, it uses kindergarden-like a good rating, Acceptable, Marginal and Poor In addition to this, cars that are exceptionally well in all crash tests are giveon one of two prizes, each more important than the other Top safety pick or top pick for the best safety performance cars.
Unlike tests NHTSA, these evaluations are not correlated to a risk of injury because the IIHS evaluates how the vehicle performs overall structure, not just the occupants wondering how different the two frontal tests are together other, the two organizations believe that the tests do not compete but complement to NHTSA crash test NHTSA side impact in the test, both dummies crash test representing midsize men are put in the car a is seated in the driver's seat and at the rear, behind the driver while the vehicle is struck by a barrier 1368 kg 3015 pounds traveling at 5 mph 38 62 km h computers connected to the dummies measures the strength of the impact on the head, neck, chest and pelvis, but the star ratings are used to show that the risk of serious chest injuries NHTSA reports separately in the interest of safety in the event of serious injury to the head These are side impact tests Notes 5 stars means 5 or less chance of serious Inju ry 4 Stars 6-10 meaning risk of serious injury which means 3 stars 11 -20 serious injury 2 stars means serious injury 21-25 1 star means 26 or more chance of IIHS Crash test severe side impact injury, Naturally IIHS side took the test a little different impact of first, both models represent small women or children, but they are placed as second in the NHTSA test all the deformable barrier is a different shape, weighs 3,300 pounds 1497 kg is greater than that used by the NHTSA.



After being slammed into the side of the vehicle at 31 mph 50 km h, computers measure the potential of serious injuries to the head, neck, chest, abdomen, pelvis and femur of the crash test dummies of the test score also includes brands good Poor to assess the severity of the accident on the dummies Because this test is so severe, it emulates almost an accident in which the car of the victim is slammed by a full-size SUV rollover test NHTSA for now, only leads NHTSA rollover of the US tests have been implemented since 2004, the test actually includes static test and a movement of a movement test consists of a vehicle calibrated simulate being loaded with five passengers and a full tank of the vehicle fuel is then set to simulate and emergency lane change while computers measure movement tire If two tires simultaneously raise at least 2 inches 5 1 what ntimètres the ground, the car is considered the risk of rollover The results are evaluated as other tests.
5 stars means 10 or less risk reversal 4 stars signifying 20.10 Risk 3 star rollover which means 20 to 30 may travel on two stars, which means 30-40 may ride on a star to say 40 or more rollover risk IIHS rear crash test NHTSA to complete again, now the IIHS is the only US organization to assess protection against rear collisions as in the rollover test NHTSA, the two static tests and movement are necessary for the IIHS to evaluate protection against static back a collision, a crash test dummy dimensioned as an average adult man is placed in the driver's seat, which is inclined about 25 degrees the headrest must be 3 5 inch roughly 8 9 cm from the top of the head and less than four inches January 10 centimeters from the back of the head If adjustable in most cases, my ures are taken both in the down position and the most favorable position as in other IIHS tests, a rating that goes from good to poor is given.
Only constraints get the proper odds or acceptable pass the test of movement, wherein the same manikin to sit in the driver's seat The vehicle is then placed on a sled that simulates the car being slammed by another vehicle weighing similarly at 20 mph 32 km h rear computers can measure impact forces that acted on the head, neck, spine and torso a combined overall score between static and movement test then performed at reduced speed of IIHS test bumper another crash test that is skipped by NHTSA but conducted by the IIHS is the low speed bumper test vehicle crashed twice at 5 mph 8 km h in a flat barrier at the front and rear bumpers, once in a sloping barrier with the front bumper and a rear post short with the bumper the good habit of bad grades are then given, but it ette times they are based on accident repair costs.
In another similar Auto Guide, we will talk about two other major international crash test organization Euro NCAP and ANCAP down under.
