Faults in the product such as fault currents flowing through the leakage path, overheating of components or parts, poor contact, etc. may cause a flame, which may then be directed to nearby parts.
The needle flame test simulates the internal part of the product. A small flame is generated under fault conditions and the risk of ignition is assessed using simulation techniques. For small parts (or components) Glow-wire test or horizontal-vertical combustion test method is not suitable, can be cited needle flame test method. If the test sample is ignited during the glow-wire test, the resulting combustion hazard is subject to a needle-flame test. Needle flame tester for electrical and electronic products, household appliances parts, components and components, such as:
wiring board, centrifugal switch, rice cooker socket ... ....
Standard:
in line with international GB / T5169.5 and GB / T 4706.1 standard "needle flame test method" requirements.
