TH8056A Touchscreen Needle Flame Tester
Category:
The TH8056 needle‑flame tester employs a needle‑shaped burner of specified dimensions (Φ0.9 mm), supplied with a designated fuel gas (butane), to apply a controlled flame to the test specimen at a 45° angle for a set duration. The test evaluates the ignition hazard posed by small flames generated under fault conditions within equipment, based on whether the specimen ignites, the duration of sustained combustion, and the length of the burning path. The needle‑flame test is a standardized procedure—specified in IEC 60695‑11‑5, GB/T 5169.5‑2008, and GB 4706.1‑2005—that uses a small flame as an ignition source to simulate potential fire hazards. It is applicable to research, production, and quality‑control departments for electrical and electronic equipment—including lighting devices, low‑voltage apparatus, household appliances, machine‑tool electrical components, motors, power tools, electronic instruments, electrical measuring instruments, electrical connectors, and related accessories—as well as to industries dealing with insulating materials, engineering plastics, and other solid combustible materials.
