摘要： 汽车内饰材料烟密度等级试验方法是按照GB/T 8627-2007《建筑材料燃烧或分解的烟密度试验方法》进行的。在试验过程中，一些因素对烟密度等级检测结果的影响较大，甚至会直接影响到符合性的判定。通过对整个试验过程中可能对烟密度测定结果产生影响的因素进行分析探讨，对个别重要因素的影响程度进行试验论证，并对烟密度等级的不确定度进行评定，为烟密度等级的相关试验提供借鉴，提高测试结果的准确度和可靠性。

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.
