ZY-7007-A Needle Flame Testing Machine
*Applicable scope:
The needle flame tester is suitable for the research, production, and quality inspection departments of electrical and electronic equipment and its components, such as lighting, low-voltage appliances, household appliances, machine tool appliances, motors, electric tools, electronic instruments, electrical instruments, information technology equipment, electrical affairs equipment, electrical connectors, accessories, etc. It is also suitable for the insulation materials, engineering plastics, or other solid combustible materials industry.
*Compliant with standards:
Requirements of relevant standards such as GB4706.1, GB5169.5-2008, IEC60695-2-2, IEC60695-11-5-2016, etc
*Experimental principle:
A needle flame tester is a device that uses a needle shaped burner with a specified size (0.9mm) and a specific gas (butane) to ignite the test sample at a 45 ° angle. The fire hazard of small flames caused by internal fault conditions is evaluated based on whether the test sample is ignited, the duration of ignition, and the length of combustion.
*Product features:
1. The characteristic of this experimental equipment is that the combustion chamber and main mechanical parts are made of stainless steel, with exquisite design and resistance to smoke corrosion. The control system has a high degree of automation, with imported key components, digital display time, three-dimensional adjustable fixtures, automatic control of test programs, independent ventilation, convenient observation and recording, and stable and reliable use.
2. The outer shell and important components of the test chamber are made of stainless steel, which is resistant to smoke and gas corrosion. The control system has a high degree of automation and has an automatic ignition function. Temperature and time digital display, easy to observe and record, stable and reliable to use.
