Abstract:

The smoke density for automobile interior materials is carried out according to the test method for density of smoke from the GB/T 8627-2007 burning or decomposition of building materials. During the experiment, some factors have great influence on the test results, which will affect the determination of compliance directly. The factors that may affect the result of smoke density during the whole experimentation were analyzed and discussed, and the influence degree of individual important factors was demonstrated experimentally and the uncertainty of the smoke density grade was evaluated. The study was to provide reference correlated experiments of the smoke density grade, and improved the accuracy and reliability.

Key words: uto interior material, smoke density, influence factor, uncertainty
