The needle flame test uses a needle-shaped burner of a specified size (0.9 mm), supplied with a specific gas (butane or propane), to apply a flame to the test specimen at a 45° angle for a set duration. The flammability risk of small flames caused by fault conditions within the equipment is assessed based on whether the specimen and the ignition support layer ignite, the duration of combustion, and the length of the flame.
Application
The needle flame tester is widely used in various fields, including but not limited to the following applications:
Electrical and electronic equipment: Used to evaluate the flame retardant performance of electrical and electronic products, ensuring the safety of equipment under abnormal conditions.
Household appliances: Used to test the flame retardant performance of materials inside household appliances, ensuring home safety.
Building materials: Used to evaluate the flame retardant performance of building materials, ensuring the safety of building structures.
Automotive interior parts: Used to evaluate the flame retardant performance of automotive interior parts, ensuring safety inside the vehicle.
Aerospace materials: Used to evaluate the flame retardant performance of aerospace materials, ensuring flight safety.
The needle flame tester assesses the flammability risk of materials by simulating small flames under fault conditions. It complies with international and domestic standards and is an important tool for improving product fire safety performance and ensuring personal and property safety.
