The Insurance Institute for Highway Safety (Insurance Institute for Highway Safety), is an important part of world safety standards.
will have in Europe and the Americas each year very systematic and professional crash tests, carried out for each vendor star classification models derived from the safety performance index, the index for these safety car sales are of great help, promote investment in research each depot security. The index reflects the degree of safety for car occupants and pedestrians under various crash conditions that may be encountered.
It IIHS evaluation items comprising: a front end side corner impact, side impact, rear impact and roof strength testing of the cervical spine. In addition to the basic test, IIS also often some special collision, such as will be hit to the evaluation of the safety performance of vehicles, and 128Km / h per hour crashed into a solid immovable wall, which made us look very enjoyable , but it also was part of the vendor dissatisfaction.
IIHS highlighted distal offset collision (offset crash test), and with the “minimum acceptable index” to indicate vehicle safety information. Excellent respectively ( G ood), good ( A cceptable), pass ( M arginal) difference ( P oor) four levels and grades, providing authoritative car safety information for consumers.
IIHS highlight is on the roof strength has its own criteria. It is to use a metal plate at a constant speed and the impact angle of the roof, and then measuring the extent of roof recess. Conditions as “G (Good)” is depressed no more than 5 inches, and the roof must be able to withstand more than 4 times the impact strength of vehicle weight; the same degree of strength of the recess can bear more than 3.25 times the weight of the vehicle 4 when times or less, was evaluated as “A (Acceptable: allowable range)”; 2.5 times or 3.25 times or less, evaluated as “M (Marginal: the bottom line of the allowable range)”; when less than 2.5-fold, was evaluated as “P ( poor: poor). ”
crash tests and domestic (e.g., C-NCAP) is different, with the IIHS will select the lowest test models, if required by the manufacturer, can be the vehicle for the optional high withRe-test, but the results must be published together with the low allocation models.
