IEC 60695-2-2 Needle Flame Flammability Test Chamber PLC Control
Test principle:
Needle flame tester is a needle burner with a specified size (φ 0.9mm), with specific gas (butane), with 45° Angle timing and directional burning test, depending on whether the test is ignited and holding the combustion time and combustion length to assess the fire risk of small flame caused by fault conditions inside the equipment.
Equipment advantages:
The device can give a quick and accurate warning: the time from 100°±5°C to 700°±3°C is 23.5s ±1s. When combustible occurs within the equipment due to failure conditions, the fire hazard of the equipment is assessed by the time and length of time the sample can be ignited or burned.
Needle flame test box is equipped with advanced PLC control, 7 "color touch screen, easy to operate.
Mainly used in lighting equipment, low-voltage electrical appliances, household electrical appliances, machine tools, and other components of the research, production and quality testing departments. Also suitable for insulating materials, engineering plastics or motor, power tools, electronic instruments, electrical instruments, electrical connectors, electrical and electronic equipment and other solid burning materials industry.
