Basic introduction:
A needle flame test is IEC60695 -11-5, and other standard GB / T5169.5-2008, GB4706.1-2005 the use of small-flame ignition source simulation project.
2, CRS-NFT needle flame tester is the required size (Φ0.9mm) needle burner, through to a specific gas (butane), the orientation angle of 45 ° timed test-fired facilities, depending on whether the ignition test and holding burning time and burn length to assess the internal condition of the equipment due to failure caused by small flame of fire risk.
3, CRS-NFT needle flame test instrument for research 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, components production and quality control departments, but also for insulation, plastic or other solid combustible materials industry.
Technical parameters:
