Applications:
• Electronics and Electrical Appliance Industry: Used for testing the horizontal/vertical flammability of plastic components and insulating assemblies in lighting equipment (LED lamps, fluorescent lamps), low-voltage electrical appliances (relays, contactors), household appliances (refrigerators, washing machines), machine tool electrical appliances, motors, power tools, electronic instruments, and electrical meters. It determines the flammability ratings of HB&V class and 5V class.
• Information Technology Equipment Industry: Evaluates the combustion safety of plastic casings and internal insulating parts of equipment such as computer hosts, printers, routers, and servers in accordance with the standards of GB/T 4943.1-2022 and IEC 60695, so as to ensure the safe use of the equipment.
• Materials Industry: Applies to engineering plastics (ABS, PC, PA), insulating materials (epoxy glass cloth boards, polyimide films), solid combustible materials, etc. Through horizontal/vertical combustion tests, it measures the combustion performance parameters of materials, providing a basis for material modification and selection.
