Abstract Based on the national standard Test on Electric and Optical Fibre Cables under Fire Conditions — Part 12:Test for Vertical Flame Propagation for a Single Insulated Wire or Cable

— Procedure for 1 kW Pre-mixed Flame(GB / T 18380.12 - 2022 / IEC 60332 - 1 - 2:2015)and Test on Electric and Optical Fibre Cables under Fire Conditions — Part 22:Test for Vertical Flame Propagation for a Single Small Insulated Wire or Cable — Procedure for Diffusion Flame(GB / T 18380.22 - 2008 / IEC 60332 - 2 - 2:2004),the vertical flame retardancy test method of single wire and cable is traced and analyzed and especially the ignition source and its location are interpreted in detail. In addition,the influencing factors of the test are summarized and analyzed.
