Crash test
open-in-new
<h2 id="types">Types</h2> <ul><li>Frontal-impact tests: which is what most people initially think of when asked about a crash test. Vehicles usually impact a solid <a href="/facts/Concrete/K6whGVNx">concrete</a> wall at a specified speed, but these can also be vehicle impacting vehicle tests. <a href="/facts/SUV/qAeED6XM">SUVs</a> have been singled out in these tests for a while, due to the high ride-height that they often have.</li> <li>Moderate Overlap tests: in which only part of the front of the car impacts with a barrier (vehicle). These are important, as impact <a href="/facts/Forces/LNAUWMwK">forces</a> (approximately) remain the same as with a frontal impact test, but a smaller fraction of the car is required to absorb all of the force. These tests are often realized by cars turning into oncoming traffic. This type of testing is done by the U.S.A. <a href="/facts/Insurance_Institute_for_Highway_Safety/RvLvfLfo">Insurance Institute for Highway Safety</a> (IIHS), <a href="/facts/Euro_NCAP/lu7NCEUs">Euro NCAP</a>, <a href="/facts/Australasian_New_Car_Assessment_Program/aUnVF4CA">Australasian New Car Assessment Program</a> (ANCAP) and <a href="/facts/ASEAN_NCAP/pgqaheou">ASEAN NCAP</a>.</li> <li>Small Overlap tests: this is where only a small portion of the car's structure strikes an object such as a pole or a tree, or if a car were to clip another car. This is the most demanding test because it loads the most force onto the structure of the car at any given speed. These are usually conducted at 15–20% of the front vehicle structure.</li> <li><a href="/facts/Side_collision/T4FoemyV">Side-impact</a> tests: these forms of accidents have a very significant likelihood of fatality, as cars do not have a significant <a href="/facts/Crumple_zone/4eaSKpx0">crumple zone</a> to absorb the impact forces before an occupant is injured.</li> <li>Pole-impact tests: A difficult test which places a large amount of force on a small proportion on the side of the vehicle.</li> <li><a href="/facts/Vehicle_rollover/7jWlWGEP">Roll-over</a> tests: which tests a car's ability (specifically the <a href="/facts/Pillar_(car)/KGsBP7Ag">pillars</a> holding the roof) to support itself in a dynamic impact. More recently, dynamic rollover tests have been proposed in lieu of static crush testing (video).<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a></li> <li>Roadside hardware crash tests: are used to ensure <a href="/facts/Crash_barrier/eYynyFKs">crash barriers</a> and crash cushions will protect vehicle occupants from roadside hazards, and also to ensure that guard rails, sign posts, light poles and similar appurtenances do not pose an undue hazard to vehicle occupants.</li> <li>Old versus new: Often an old and big car against a small and new car,<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a><a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> or two different generations of the same car model. These tests are performed to show the advancements in crash-worthiness.</li> <li>Computer model: Because of the cost of full-scale crash tests, engineers often run many <a href="/facts/Crash_simulation/RTM9yoFY">simulated crash tests</a> using computer models to refine their vehicle or barrier designs before conducting live tests.</li> <li>Sled testing: A cost-effective way of testing components such as airbags and seat belts is conducting sled crash testing. The two most common types of sled systems are reverse-firing sleds which are fired from a standstill, and decelerating sleds which are accelerated from a starting point and stopped in the crash area with a hydraulic ram. It can also be used to evaluate the <a href="/facts/Whiplash_(medicine)/RhbC0F9y">whiplash</a> protection of a vehicle's <a href="/facts/Car_seat/MQbMHqSW">seat</a>.</li></ul> <h2 id="major-providers">Major providers</h2> <table><tbody><tr><th>Name</th><th>Abbreviation</th><th>Founded</th><th>Location</th></tr><tr><td><a href="/facts/US_NCAP/hz6QB8SN">United States New Car Assessment Program</a></td><td>US NCAP (U.S. NCAP)</td><td>1978</td><td><a href="/facts/Washington,_DC/enXPK156">Washington, DC</a>, USA</td></tr><tr><td><a href="/facts/Insurance_Institute_for_Highway_Safety/RvLvfLfo">Insurance Institute for Highway Safety</a></td><td>IIHS</td><td>1959, first crash test 1969, ratings from 1995</td><td><a href="/facts/Arlington_County,_Virginia/NlfCfCQM">Arlington, VA</a>, USA</td></tr><tr><td><a href="/facts/Australasian_New_Car_Assessment_Program/aUnVF4CA">Australasian New Car Assessment Program</a></td><td>ANCAP</td><td>1993</td><td>Canberra, Australia</td></tr><tr><td>Japan New Car Assessment Programme</td><td>JNCAP</td><td>1995</td><td>Tokyo, Japan</td></tr><tr><td><a href="/facts/Euro_NCAP/lu7NCEUs">European New Car Assessment Programme</a></td><td>Euro NCAP</td><td>1996</td><td><a href="/facts/Leuven/zkKTDkzH">Leuven</a>, Belgium</td></tr><tr><td>Korean New Car Assessment Programme</td><td>KNCAP</td><td>1999</td><td>Seoul, South Korea</td></tr><tr><td><a href="/facts/C-NCAP/FvyAu5qD">China – New Car Assessment Programme</a></td><td>C-NCAP</td><td>2006</td><td>Tianjin, China</td></tr><tr><td><a href="/facts/Latin_NCAP/35384yVI">Latin New Car Assessment Programme</a></td><td>Latin NCAP</td><td>2010</td><td>Montevideo, Uruguay</td></tr><tr><td><a href="/facts/ASEAN_NCAP/pgqaheou">New Car Assessment Program for Southeast Asia</a></td><td>ASEAN NCAP</td><td>2011</td><td><a href="/facts/Kajang/fMz89wbv">Kajang</a>, <a href="/facts/Selangor/5gKNfr9G">Selangor</a>, Malaysia</td></tr><tr><td><a href="/facts/Global_NCAP/VueezM3f">Global New Car Assessment Programme</a></td><td>Global NCAP</td><td>2011</td><td>London, Great Britain</td></tr><tr><td><a href="/facts/Taiwan_New_Car_Assessment_Program/br8NsdIb">Taiwan New Car Assessment Program</a></td><td>TNCAP</td><td>2018, ratings from 2023</td><td><a href="/facts/Changhua_County/8ASeVqNX">Changhua</a>, Taiwan</td></tr><tr><td><a href="/facts/Green_NCAP/rovauVW9">Green NCAP</a> (operated by <a href="/facts/Euro_NCAP/lu7NCEUs">Euro NCAP</a> for emissions)</td><td>Green NCAP</td><td>2019</td><td><a href="/facts/Leuven/zkKTDkzH">Leuven</a>, Belgium</td></tr><tr><td><a href="/facts/Bharat_NCAP/oNtPlbh8">Bharat New Car Assessment Program</a></td><td>Bharat NCAP</td><td>2023</td><td>Pune, India</td></tr></tbody></table> <ul><li><a href="/facts/ARCAP/9ab4GFdn">Auto Review Car Assessment Program</a> (ARCAP)</li> <li><a href="/facts/Allgemeiner_Deutscher_Automobil-Club/jeHWH8nC">Allgemeiner Deutscher Automobil-Club</a> (ADAC) in Germany</li> <li><a href="/facts/National_Highway_Traffic_Safety_Administration/hz6QB8SN">National Highway Traffic Safety Administration</a> (NHTSA) in the United States, specifically the Federal Motor Vehicle Safety Standard (FMVSS) and New Car Assessment Program (NCAP)</li></ul> <h2 id="data-collection">Data collection</h2> <p>Crash tests are conducted under rigorous <a href="/facts/Scientific/IJoaD7rs">scientific</a> and <a href="/facts/Safety/jyH5HLSg">safety</a> <a href="/facts/Standardisation/vS9AhNMS">standards</a>. Each crash test is very expensive so the maximum amount of <a href="/facts/Data/AUBFN97o">data</a> must be extracted from each test.
