Control system of needle flame tester

Control system of needle flame tester

*1.yesIEC 6 0695-11-5：2004 TheIEC60695 -11-5、GB/T5169.5-2008、GB4706.1-2005The needle flame test uses a needle shaped burner with a specified size (0.9mm), supplied with specific gas (butane or propane), and directed at a 45 ° angle to ignite the test sample. The ignition hazard of small flames caused by fault conditions inside the equipment is evaluated based on whether the test sample and the ignition cushion layer are ignited, the holding time, and the combustion length.
2.The needle flame tester is suitable for research, production, and quality inspection departments of electrical and electronic equipment and their components, such as lighting, low-voltage electrical appliances, household appliances, machine tool appliances, motors, power tools, electronic instruments, electrical instruments, information technology equipment, electrical affairs equipment, electrical connectors, accessories, etc. It is also suitable for industries such as insulation materials, engineering plastics, or other solid combustible materials.
