With respect to the reaction to fire performance of sandwich panel products, in ISO/TC92/SC1/WG7 “Large and intermediate scale fire test methods,” ISO 13784-1 “Reaction to fire test for sandwich panel building systems—Part 1: Small room test” is specified as a method of test for determining the reaction to fire behavior of sandwich panel building systems. On the other hand, according to EN 13501-1 “Fire classification of construction products and building elements,” EN 13823 (SBI test) and EN ISO 11925-2 (ignitability test) are used especially for evaluating the classes B, C, and D in the Euroclass system. The authors have developed a new intermediate-scale box test for sandwich panel products, pertaining to the correlation with ISO 13784-1 especially on the flashover occurrence, which was locally standardized as JIS A 1320:2017, and is now internationally being discussed as ISO/WD TS 23657 at ISO/TC92/SC1/WG7. In this paper, regarding five sandwich panel specimens, various fire tests were conducted according to ISO 13784-1, EN 13501-1, and ISO/WD TS 23657, and those results were compared with each other, indicating that ISO/WD TS 23657 has a good correlation with ISO 13784-1 in terms of flashover, and that evaluation results based on ISO/WD TS 23657 could be similar to those based on EN 13501-1. Furthermore, a new tentative classification system was proposed based on those limited experimental results conducted in this research.

与 ISO 13784-1 室内测试和 EN 13501-1 分类系统相比,针对夹层板产品开发了一种新的中等规模箱式测试

关于夹层板产品对防火性能的反应,在 ISO/TC92/SC1/WG7“大型和中型防火测试方法”,ISO 13784-1“对夹层板建筑系统的防火测试的反应——第 1 部分:小房间测试”被指定为一种测试方法,用于确定夹层板建筑系统对火灾行为的反应。另一方面,根据 EN 13501-1“建筑产品和建筑构件的防火分类”,EN 13823(SBI 测试)和 EN ISO 11925-2(可燃性测试)专门用于评估 B、C 和D 在 Euroclass 系统中。作者为夹芯板产品开发了一种新的中间规模箱测试,涉及与 ISO 13784-1 的相关性,特别是闪络发生的相关性,在当地被标准化为 JIS A 1320:2017,并且现在在 ISO/TC92/SC1/WG7 中作为 ISO/WD TS 23657 在国际上被讨论。在本文中,对于五个夹层板试样,根据 ISO 13784-1、EN 13501-1 和 ISO/WD TS 23657 进行了各种防火测试,并将这些结果相互比较,表明 ISO/WD TS 23657在闪络方面与ISO 13784-1具有良好的相关性,基于ISO/WD TS 23657的评估结果可能与基于EN 13501-1的评估结果相似。此外,基于本研究中进行的那些有限的实验结果,提出了一种新的暂定分类系统。并将这些结果相互比较,表明 ISO/WD TS 23657 在闪络方面与 ISO 13784-1 具有良好的相关性,并且基于 ISO/WD TS 23657 的评估结果可能与基于 EN 13501 的评估结果相似-1. 此外,基于本研究中进行的那些有限的实验结果,提出了一种新的暂定分类系统。并将这些结果相互比较,表明 ISO/WD TS 23657 在闪络方面与 ISO 13784-1 具有良好的相关性,并且基于 ISO/WD TS 23657 的评估结果可能与基于 EN 13501 的评估结果相似-1. 此外,基于本研究中进行的那些有限的实验结果,提出了一种新的暂定分类系统。
