In 2019, we introduced () as a universal dimensionless index for the classification of flame-retardant polymer materials ( 2019, (3), 407). simply takes the peak of Heat Release Rate (pHRR), Total Heat Release (THR), and Time-To-Ignition () from cone calorimetry data and quantifies the flame retardancy performance of polymer composites with respect to the blank polymer (the reference sample) on a logarithmic scale, as of ( ˂ 10), (10 ≤ ˂ 10), or ( ≥ 10). Although initially applied to categorize thermoplastic composites, the versatility of was later verified upon analyzing several sets of data collected from investigations/reports on thermoset composites. Over four years from the time was introduced, we have adequate proof of reliability for polymer materials ranking in terms of flame retardancy performance. Since the mission of was to roughly classify flame-retardant polymer materials, its simplicity of usage and fast performance quantification were highly valued. Herein, we answered the question "does inclusion of additional cone calorimetry parameters, e.g., the time to pHRR (), affect the predictability of ?". In this regard, we defined new variants to evaluate classification capability and variation interval of . We also defined the () based on Pyrolysis Combustion Flow Calorimetry (PCFC) data to invite specialists for analysis of the relationship between the and , which may deepen our understanding of the flame retardancy mechanisms of the condensed and gas phases.
2019年，我们引入了（）作为阻燃聚合物材料分类的通用无量纲指数（《2019年》，（3），407）。（）仅从锥形量热法数据中获取热释放速率峰值（pHRR）、总热释放量（THR）和点火时间（），并以对数尺度量化聚合物复合材料相对于空白聚合物（参考样品）的阻燃性能，分为（˂10）、（10≤˂10）或（≥10）。尽管最初用于对热塑性复合材料进行分类，但（）的通用性后来在分析从热固性复合材料的调查/报告中收集的几组数据时得到了验证。自引入（）以来的四年多时间里，我们有充分的证据证明其在聚合物材料阻燃性能排名方面的可靠性。由于（）的任务是对阻燃聚合物材料进行大致分类，其使用的简便性和快速的性能量化受到高度重视。在此，我们回答了“纳入额外的锥形量热法参数，例如达到pHRR的时间（），是否会影响（）的可预测性？”这一问题。在这方面，我们定义了新的变体来评估（）的分类能力和变化区间。我们还基于热解燃烧流动量热法（PCFC）数据定义了（），以邀请专家分析（）与（）之间的关系，这可能会加深我们对凝聚相和气相阻燃机理的理解。
