What is The Fabric Flammability Test Method ?


Fabric Flammability Test Method ?


Vertical Flammability Chamber used for testing the flame retardant performance of afterflame, afterglow and carbonization of all farics in vertical direction. Comprises a draft free stainless steel cabinet with observation window and back wall painted black for easy test viewing. The different specimen holders and associated hardwares are dependent on the test standards.

Textile Flammability Testing Principle


Vertical Flame Test Chamber Under controlled laboratory conditions, material response to heat and flame is measured and described. A test specimen is positioned vertically above a controlled flame and exposed for a specified period of time. Following exposure, the flame source is removed. Measurements are made on the length of time that the specimen continues to flame and the time afterglow continues after the flame source has been removed. Char length, or visible damage to the test specimen after application of a specified tearing force, is determined. Notations on observations of melting and dripping are also recorded.

Flammability Testing Test Steps


1. Put the prepared sample into the fixture and hang it in the Vertical Flammability Testing Chamber.

2. Turn on the power of the device.
3. Select the language to enter the test interface.
4. Click the "Positive" button in the test interface tolet the burner run directly below the sample.
5. Use flame measuring scale to measure the distance betweenthe burner and the sample and adjust the position of the sample.
6. After adjustment, click“Rst", turn the burner back to initial position.
7. Set Flame Application time on test Interface, turn on the air source, click"AirSource", click"Ignition”(Initial ignite need to wait a while)
8. Turn the gas knob to adjust the flame size.
9. After the flame adjustment is complete, click Start.According to the burning state ofthe sample, click the "Afterflame time" button and “Aftergow time" button respectively.
10. After the combustion is completed, remove the sample.
11. Select the corresponding weight according to the sample,hang it on the sample to straighten the sample, and measurethe burning distance of the sample with a measuring ruler.
