What Criteria to Consider when Using the Vertical Flammability Tester ( Flame Chamber) to Test the Flammability?

1. When making a sample, the sewn material must be the same as the material composition and size used for sewing garments and the same seam method. The trim used lengthwise should be stitched to the full width (shorter side) of the specimen, and the trim not used lengthwise should be stitched to the full length (longer side) of the test specimen.What Criteria to Consider when Using the Vertical Flammability Tester to Test the Flammability?

2. After drying the sample in the dryer, cooling time should not exceed 60 minutes.

3. When adjusting the flame length of the burner, the lighting of the extraction cabinet and the extraction fan should be turned off to dim the ambient light, and air should be turned off. After the flame length has been initially adjusted, it should be allowed to burn for a period of time before checking to ensure Flame length stability. When adjusting the position of the burner, the blue outer flame of the flame should be brought into contact with the lower edge of the test specimen and the lower edge of the test specimen should be equally divided in order to ignite the test sample most effectively. Remove the sample from the dryer to start the ignition combustion. This must be completed within 45 seconds, if it is longer than 45 seconds, the sample must be re-dried and cooled before testing.

4. When carrying out the burning test, some materials will produce smoke with high toxicity. When the test is carried out, a gas mask, safety glasses and the like should be worn. When the burning of each sample is completed, an exhaust fan should be used prevent excessive smoke that may harm and pollute the environment.

  • A bench mounted draft free combustion chamber having a large inside volume of 1.0m3 and fitted with an interior light and exhaust fan to enable simple evacuation of combustion products.
  • Large door and window made from toughened safety glass giving a generous view of the specimen during a test.
  • Specimen holders.
  • Fully adjustable horizontal and vertical specimen supports.
  • A burner in compliance with ASTM D 5025, with simple angle adjustment (0°, 20°, 45°) and precision gas control system including gas flow meter, pressure regulator and pressure gauge.
  • Two access ports enabling easy entry to the chamber for movement of the burner and specimen.
  • A burner wing tip.
  • Three digital test duration timers for accurate but simplified operation.
