本试验方法能够评估非承重外墙组件的火灾蔓延特性。该试验通过评估外表面上的火势蔓延、从火羽流到外表面的热流以及试样内的火势蔓延来确定外墙组件的比较燃烧特性。

This test method enables an assessment of the fire spread characteristics of non-load bearing exterior wall assemblies. The test determines the comparative burning characteristics of exterior wall assemblies by evaluating fire spread over the exterior surface, heat flow from the fire plume to the exterior surface, and fire spread within the test specimen.
