Needle Flame Tester

Product description

Needle flame tester is the needle-shaped burner by a certain size, fill the inside with a specific gas (butane), and at 45 ° angle by fixed time and certain direction to test products, Assess the fire hazard of small flames caused by fault conditions inside the equipment, depending on the test sample Whether ignited, and its ignition time and combustion Length.

Standards

GB / T 4207-84. IEC 6112. ASTM D3638. DIN 53480 and UL 746A test methods

Scope of application

Needle flame tester used not only for low-voltage electrical appliances, power tools, machine tools, electrical instruments, household appliances, electrical, electronic equipment, lighting, electrical connections, accessories and other electrical and electronic equipment and components, components research, production and quality Departments, but also for insulating materials, engineering plastics or other solid combustible materials industry

Product features

1. completely independent of electricity, gas design, use safely

2. military-grade explosion-proof glass

3. the unique delay exhaust system, the machine can continuously run after the exhaust ventilation which can be preset 1 ~ 3min

4. box with high hardness stainless steel

Experimental principle

Needle flame tester burns the test sample In a 45 °angle direction  timingly  by using a specified size (Φ0.9mm) needle-like burner which have a specific gas  (butane) . The dangerous accessment of the small flames caused by the failure conditions within the equipment depends on whether the test product ignite and the ignition time and the length of the combustion.

Features

1. The charcater of test equipment :burning box and the main mechanical parts is made of stainless steel what is good looking 、smoke resistance corrosion.The Control system has a higher degree automation,  imported key components , digital time, three-dimensional adjustable fixture, automatic control of test procedures, independent ventilation, easily used observation and recording, stable and reliable.

2. test box shell and important parts is made of stainless steel, smoke resistantly, gas corrosion. The control system has a high degree of automation and automatic ignition function. Temperature and time are digital displayed, easy to observe and record. The control system is stable and reliable.

FAQ

1. What is the purpose of the needle flame test?

It evaluates the ignition risk and flame resistance of electrical products and materials under small flame exposure, simulating fault conditions.

2. What gas is used for the needle flame test?

Typically, 95% butane gas is used, supplied by the user.

3. Can the flame height and duration be adjusted?

Yes. Both flame height and application/hold time are adjustable for precise testing.

4. Are there safety measures for gas leaks?

Yes. The optional gas alarm system can detect leaks and trigger alarms. Automatic gas shut-off is also included.

5. Can this device be used for all materials?

It is suitable for solid materials and electrical components. Liquids or specimens that cannot be fixed in the holder are not suitable for this test.
