The UL94 flame chamber is a test device for testing the combustion properties of materials and is widely used in the electronics, building materials, automotive and other industries. The following are the operating methods and precautions for this tester:
Operation method:
(1) Place the sample to be tested on the tester's sample holder and adjust the position and height of the sample so that it is perpendicular to the flame.
(2) Ignite the tester's flame and adjust the flame height and angle to meet the test requirements.
(3) The tester will automatically record the burning time and afterburning time of the sample and assess the burning performance of the sample based on the test results.
Cautions:
(1) The tester should be placed in a well-ventilated area free from flammable materials to ensure the safety of the testing process.
(2) All parts of the tester should be checked for proper functioning before testing, e.g. flame height, angle, etc. to meet the test requirements.
(3) During the test, the sample should be observed for changes and the test should be stopped promptly if there is burning or dripping.
(4) All parts of the tester should be cleaned promptly after the test to keep the tester clean and safe.
(5) The tester should be regularly maintained and serviced, such as replacing the flame head, cleaning the sample holder, etc.
In summary, the operation of UL94 flame chamber requires attention to safety, accuracy and reliability, and the need to comply with relevant operating procedures and precautions to ensure the accuracy and reliability of test results.
