GB/T 5169.13-2024 is Part 13 of the series of standards for fire hazard testing of electrical and electronic products. It specifies the test method for determining the glow-wire ignition temperature (GWIT) of materials and is applicable for assessing the fire safety of materials used in electrical and electronic products. The core of the standard involves applying a specified heat input to the test specimen using a nickel-chromium glow-wire, and recording the minimum temperature at which the material ignites and sustains combustion for more than 5 seconds, thereby characterizing the material's resistance to glow-wire ignition. The test requires the use of standardized glow-wire test apparatus, high-precision temperature measurement systems, accurate timing equipment, along with specimen fixation devices and specialized test chambers, while controlling parameters such as contact pressure and duration. This provides a unified technical basis for material selection and safety quality control of electrical and electronic products.
