NFT Needle Flame Tester

Introduction:

It is in accordance with national standards IEC60695-2-2 and IEC60695-11-5 to design and produce.

The tester applies for lighting, low-voltage electrical equipment, household appliances, electrical machines, motors, power tools, electronic equipment, electrical instruments, electrical connectors, accessories and other electrical and electronic equipment and parts, component research, production and quality control departments and insulating materials , plastic or other solid combustible materials industry to carry on  small-flaming ignition experiments.

Needle flame tester uses standard size (Φ0.9mm) needle burner .and burns the sample with specific gas (butane) at the angle of 45 °.

We determine the ignition risk of  the small-flame caused by fault conditions in the equipment by testing the sample burning situation ,burning time and burning  length.
