In order to analyze the importance of mounting and fix-ing 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 classifica-tion 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 sub-strate,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 re-sults.Different installation methods of the specimens can lead to significant differences in the test results.Therefore,when con-ducting 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 ma-terial.
