本文件描述了一种确定被动防火材料和系统抗喷射火灾能力的方法。它指示被动防火材料在喷射火灾中的行为，并提供特定条件下的性能数据。 它不包括对被动防火材料的其他性能的评估，如耐候性、老化、抗冲击性、抗冲击性或爆炸性，或烟雾产生。 由于射流特性的破坏，完整的工字钢和立柱无法按照本文件进行测试。

This document describes a method of determining the resistance to jet fires of passive fire protection materials and systems. It gives an indication of how passive fire protection materials behave in a jet fire and provides performance data under the specified conditions. It does not include an assessment of other properties of the passive fire protection material such as weathering, ageing, shock resistance, impact or explosion resistance, or smoke production. Complete I-beams and columns cannot be tested to this document due to disruption of the characteristics of the jet.
