摘要: 为分析材料燃烧性能试验的试样安装方法的重要性,提高材料燃烧性能测试及分级评价的一致性和准确性,基于GB 8624-2012《建筑材料及制品燃烧性能分级》中的燃烧性能分级评价方法,以SBI试验为基础,探讨了试验基材、试样拼接缝、试样固定方式、空气间隙、试样受火面等因素对材料燃烧行为的影响。试验对比表明,这些试样安装的相关因素对试验结果具有显著影响,试样安装方法不同,可导致试验结果出现较大差异。因此,进行材料燃烧性能测试及分级评价时,应结合材料的实际应用来确定试样的安装方法。

Abstract: In order to analyze the importance of mounting and fixing method of specimens for reaction to fire test, and improve the consistency and accuracy of burning behavior and classification evaluation, this article is based on the burning behavior classification evaluation method in GB 8624-2012, Classification for burning behavior of building materials and products, and carry out the SBI test, explores the influence of factors such as test substrate, specimen joints, specimen fixing method, air gap, and specimen fire surface on burning behavior for building materials. The experimental comparison shows that the factors related to the installation of specimens have a significant impact on the test results. Different installation methods of the specimens can lead to significant differences in the test results. Therefore, when conducting reaction to fire test and fire performance classification evaluation, the mounting and fixing method of the specimen should be determined based on the end-use application of the material.
