C-NCAP aims at establishing high standard, fair and impartial methods for assessing vehicle safety performance under impact, so as to promote the development of vehicle technologies in pursuit of a higher concept for safety.
The intention of the programme is to provide consumers with safety information concerning the newly marketed vehicles, encourage the manufacturers to attach higher importance to safety standards, improve the safety performance and technical standards of the vehicles while giving publicity by means of the assessment process to the vehicles that excel in occupant protection. These assessment methods are to be further developed following the progress of China’s vehicle safety technology.
The C-NCAP tests consist of the following three items:
1) Frontal impact test against rigid barrier with 100% overlapping: The test shall be conducted such that the test vehicle frontally crashes against a fixed rigid barrier with 100% overlapping at an impact speed of 50 km/h (test speed not lower than 50km/h). The test vehicle approaches the
barrier in a route that does not deviate sideways from the theoretical trail by 150mm in either transverse direction. Place a Hybrid III 50 percentile male dummy in the driver’s seat and passenger seat respectively in the front row, to measure the injuries to the front seat occupants. Place a Hybrid III 5 percentile female dummy in the right-most seat of the second row, to check the performance of the safety belt.
2) Frontal impact test against deformable barrier with 40% overlapping: The test shall be conducted such that the vehicle frontally crashes against a fixed deformable endoergic barrier at an impact speed of 56km/h (test speed not lower than 56km/h). The impact overlapping width between the offset impact vehicle and the deformable barrier should be within the range of 40% of the vehicle width ±20mm. Place a Hybrid III 50 percentile male dummy in the driver’s seat and passenger seat in the front row to measure the injury to the occupants in the front seats. Place a Hybrid III 5 percentile female dummy on the left-most seat of the second row to check the performance of the safety belt.
3) Side impact test against mobile deformable barrier: The trolley fitted with a deformable barrier face to impact with the driver’s side of the test vehicle. The mobile barrier is to move in a direction perpendicular to the test vehicle, with the center line of the barrier aligned with the R point of the test vehicle, and the impact speed should be 50km/h (test speed not lower than 50km/h). The longitudinal perpendicular plane of the mobile barrier should be within ±25mm from the transverse vertical plane that passes the R point of the front row seat on the test vehicle’s impact side.
Position a EuroSID II dummy on the driver’s seat to measure the injury to the driver’s position.
A maximum score of 51 points in C-NCAP is available. The full score for each of the above tests will be 16 points, or a total of 48 points for all three of the tests. Safety belt reminder and side airbag (and side curtain airbag) are entitled to 2 points and 1 point respectively in extra. The sum
of the points for the three tests plus the additional points (rounded to one decimal place) will be recorded as the total score, which will be used to determine the star ratings based on the total score, according to the following criteria:
Total score ----------------------Star rating
≥50 points ----------------------------5+ （★★★★★☆）
45 (inclusive) - 50 points ---------5 （★★★★★）
40(inclusive) - 45 points ----------4（★★★★）
30(inclusive) - 40 points --------- 3 （★★★）
15(inclusive) - 30 points ----------2 （★★）
＜15 points ---------------------------1 （★）
