GB/T 18380.12 - 2022 introduces the test method of 1kW premixed flame for vertical spread of single insulated Wire and cable flame. The standard specifies the test principle and specifies the equipment parameters of 1kW premixed flame, such as combustion device structure, gas mixing ratio, etc. The preparation of the sample is described in detail, covering the length of interception and fixing method. Standardize the test process, including ignition time, flame application position and duration, and observe the flame spread of the cable. Through this standard, the vertical spread characteristics of a single insulated Wire and cable under a specific flame can be accurately evaluated, providing a key basis for the mass control and safety performance evaluation of cable products
