Battery flammability test chamber tests the safety performance of the battery through the combustion test. It is an indispensable testing equipment for battery manufacturers and research institutes. The battery flammability test chamber is suitable for testing the battery flame resistance of mobile phones, laptops and other small electronic consumer products. The battery flammability testing chamber from Wewon Environmental Chambers Co., Ltd. conforms to SJ/ T11169-1998, UL 1642:2008, UL 2054:2008, IEC 60086-4:2000 and other related test standards.
How to use the battery flammability test chamber ? The test method of battery flammability test chamber for lithium ion batteries fire test: Fix the screen 38.1mm above the top of the burner, The mesh screen has 20 holes per 25.4mm, and the wire diameter is 0.43mm. Ignite the burner of battery flammability test chamber and observe the combustion of the battery, Until the battery explodes or burns out. The combustion process was timed.
The lithium ion battery flammability testing chamber consists of a control box, a vertical air box, a combustion nozzle, a solenoid valve, a high-pressure igniter, a wire sample fixture, a gas pipe, a gas source, an internal and external flame regulating device, and a signal control line.
Test Requirements: Each test battery is placed on a 20 hole per inch wire mesh, 0.017 inch thick.
Combustion Particle Test (UL 2054)
The screen is placed at a distance of 1-1/38.1 mm from the burner｜Battery Flammability Test Chamber for Lithium Ion Batteries Fire Test
Fuel oil and air are sprayed at the speed of a bright blue flame, so that the wire mesh burns bright red.
One thick asbestos cloth panel is placed at a position 0.91m perpendicular to the center of the steel mesh.
One square yard of coarse asbestos cloth consisting of four layers of 0.4 to 0.6 ounces of coarse asbestos cloth per square yard.
The test sample was placed in a position where sparks or burning particles could be ejected into the center of the coarse asbestos cloth.
In some cases, it should be required to circle experimental samples in the net,The burner is then lit and the battery is watched until it explodes or is destroyed. Judgement Result: coarse asbestos cloth surface rotation should not be ignited.
Test Requirements: The experimental battery is placed on a flat table with a 4 “diameter hole in the middle and a cover plate.
Spray Test (UL 2054)
The cover plate is made of steel mesh with 20 holes per foot or 0.43 mm of steel wire.
A 610mm screen (305mm height) with 8 screens is placed around the sample.
The mesh is made of 0.25mm diameter wire 16-18 wire per inch.Wherein the relief valve orientation is parallel to the asbestos cloth.
The sample is placed on a wire mesh, covered with a hole in the center of the table, and heated until it explodes or is destroyed.
Judgement Result: No part of the exploding battery penetrates the screen, and no part or all of the battery protrudes the screen.
