China Insurance Automotive Safety Index Headlight Test
China Insurance Automotive Safety Index (C-IASI) headlight test is a test procedure for measuring and rating the on-road illumination provided by a passenger vehicle headlight system. The C-IASI plugin reproduces this test to predict the rating for headlight systems in an earlier phase of development.
China Insurance Automotive Safety Index (C-IASI) is the result of a collaboration between China
Automotive Engineering Research Institute (CAERI) and the CIRI Auto Technology Institute to
improve on-road safety levels in China. A project spearheaded by the Insurance Association of
China, the test procedures are meant to be an innovative vehicle safety evaluation system from
the perspective of insurers. The C-IASI headlight testing procedure measures and rates the
on-road illumination provided by a passenger vehicle system. The testing procedure is based on
illumination measurements on road sections with various horizontal curvatures. Headlight systems
are evaluated based on pre-defined test parameters and measurement points, and are rated on the
following scale:
: Good
: Acceptable
: Marginal
: Poor.
The rating can then be used by optical departments to evaluate the light quality and performance of beams in order to improve the lighting systems for better compliance with the standard, and to obtain higher ratings.
