A cable parameter related to the volume of effective non-combustible content, , is proposed, which depends on the ratio of non-metallic, non-combustible component volume to non-metallic, combustible component volume, and the effective area of heat transfer within the cable during the combustion process. The correctness of the proposed cable parameter for circular cables is confirmed by tests and the determination of Spearman's correlation. High Spearman's correlation factors (close to -1) were obtained for total heat release and total smoke production as a function of the cable parameter. The cable parameter might be used in selecting cable samples for large geometric-scale fire testing within the same cable family.
提出了一个与有效不燃成分体积相关的电缆参数，该参数取决于非金属不燃成分体积与非金属可燃成分体积之比，以及燃烧过程中电缆内的有效传热面积。通过测试和斯皮尔曼相关性的测定，证实了所提出的圆形电缆参数的正确性。对于总热释放和总烟雾产生作为电缆参数的函数，获得了较高的斯皮尔曼相关系数（接近-1）。该电缆参数可用于在同一电缆系列中选择用于大型几何规模火灾测试的电缆样本。
