Needle Flame Testing Equipment For Components Parts And Assemblies Of Electrical

Working principle:

Due to fault conditions in the product, such as fault current flowing through the leakage path, overheating of components or parts, poor contact, etc., flames may be caused, which may then shoot onto nearby parts. The needle flame test simulates the small flames generated inside the product under fault conditions and evaluates the fire hazard using simulation technology.

Test standards:

Complies with the test standards of GB/T5169.5 and IEC60695-2-2 "Fire hazard testing for electrical and electronic products - Part 2: Test methods - Part 2: Needle flame test".

Why use a needle flame testing machine:

Fire protection (fire prevention, flame retardancy) has always been a social safety proposition. With the improvement of China's economic level, the awareness of fire protection (fire prevention and flame retardancy) has also reached a high point. Therefore, fire prevention and flame retardancy has become a top priority for the country! So when we use electrical and electronic products, components, and components of household appliances, we also require a needle flame experiment.

Under what circumstances are household appliances, electrical and electronic products suitable for needle flame combustion testing machines

When the hot wire test or horizontal vertical combustion test method is not suitable for small parts (or components), the needle flame test method can be used. If the test sample ignites during the hot wire test, the combustion hazard generated also needs to be tested with a needle flame. needle

Note: This needle flame testing machine is one of the recommended equipment for household and similar electrical testing centers in GB/T4706 and IEC60335-1

Reference standards: IEC884-1, GB2099.1, VDE, IEC335, GB4706.1, GB5169.5, UL1694.

Technical description:

This product is base on the use of the electronic and electrical products. Due to fault conditions such as fault current flowing through leakage paths, overheating of components or parts, poor contact, etc., it may cause flames. It may also shoot on nearby parts. This test simulates the small flames generated inside the product under fault conditions and uses simulation technology to evaluate the fire hazard. When the hot wire test or horizontal vertical combustion test method is not suitable for small parts (or components), the needle flame test method can be used. If the sample ignites during the hot wire test, the combustion hazard generated also needs to be tested with a needle flame. Suitable for components and parts of electronic and electrical products, household appliances, such as wiring boards, centrifugal switches, and rice cooker sockets.
