摘要

根据ASTM E84和UL 723进行标准化的“斯坦纳隧道”测试，用于比较评估各种建筑材料和组件的表面燃烧特性，即火焰蔓延和烟雾释放。虽然这种方法对于消防安全工程师来说是众所周知的，但对于开发新的消防安全材料来满足这项测试的材料科学家来说，它并不是很好理解。了解测试如何测量可燃性和烟雾对于设计符合E84和UL 723要求的材料至关重要。本文主要讨论了ASTM E84测试，讨论了该方法的历史，它如何测量火焰蔓延和烟雾释放，以及在测试方法中安装样品如何影响火焰蔓延和烟雾释放。最后，讨论了可用于为E84试验开发的材料的定性筛选工具的测试方法。

Revisiting the “Steiner Tunnel” test method covered under ASTM E84: An overview and analysis of the test method

The “Steiner Tunnel” test, which is standardized under ASTM E84 and UL 723, is used to comparatively assess surface-burning characteristics, namely, flame spread and smoke release from a wide range of building materials and assemblies. While the method is well known to fire safety engineers, it is not as well understood by material scientists who develop new fire safe materials that will meet this test. Understanding how the test measures flammability and smoke is critical to designing materials that can meet requirements that reference E84 and UL 723. This article primarily discusses the ASTM E84 test, discusses the history of the method, how it measures flame spread and smoke release, and how mounting samples in the test method affects flame spread and smoke release. Finally, there is discussion on test methods that could be used for qualitative screening tools for materials developed for the E84 test.

期刊介绍： The Journal of Fire Sciences is a leading journal for the reporting of significant fundamental and applied research that brings understanding of fire chemistry and fire physics to fire safety. Its content is aimed toward the prevention and mitigation of the adverse effects of fires involving combustible materials, as well as development of new tools to better address fire safety needs. The Journal of Fire Sciences covers experimental or theoretical studies of fire initiation and growth, flame retardant chemistry, fire physics relative to material behavior, fire containment, fire threat to people and the environment and fire safety engineering. This journal is a member of the Committee on Publication Ethics (COPE).
