Vertical Flammability Chamber - TNG1066

The TNG1066 Vertical Flammability Chamber is designed to evaluate the flame resistance of textile materials and products through a vertical test configuration. The instrument operates by exposing a specimen to a controlled flame source and measuring the time required for ignition and subsequent burning behavior. It is suitable for testing materials such as children’s sleepwear, evening dresses, industrial wear, curtains, and resilient filling materials used in upholstered furniture. The TNG1066 supports the ASTM D6413 standard, which outlines the standard test method for flame resistance of textile materials in a vertical test. It also accommodates optional standards including 16 CFR Parts 1615/1616, which set flammability requirements for children’s sleepwear, CALIF TB 117 Method A, CPAI 84, and GB/T 5455. The chamber features an ignition time setting of 12±0.2 seconds or 3±0.2 seconds, with a distance from the igniter to the specimen of 19 mm or 17 mm. The burner dimensions are 10 mm / 11 mm with a barrel length of 76±6 mm. The time display has a range of 0–999.9 seconds with an accuracy of 0.1 seconds. Accessories include weights, a specimen holder, a flame measuring tape, a steel ruler, and a sampling plate.

• What is the Vertical Flammability Chamber?
• Vertical Flammability Chamber is designed to measure the flame resistance of textiles(vertical test) or products like children’s sleepwear, evening dress for children and adults, special industrial wearings, curtains, and so on.
• The burner ignites the specimen automatically, and the ignition time is programmable. Therefore, it is very convenient to carry out the test. And then there will be after-flame time and afterglow time on the display. It is convenient to operate the machine due to the user-friendly design of the control panel and the touch screen. Finally, the screen will show the test results when the vertical flammability test is over. Besides, it is comprised of a draft-free stainless steel flammability chamber with an observation window for easy test viewing. Moreover, specimen holders, burners, and associated hardware are dependent on the test standard and must be specified.
• Vertical flame resistance test standards of textiles
• There are many test methods for flame resistance of textiles, and different kinds of fabrics have different test methods. The applicable standard for vertical flame test of is briefly introduced below.
• ASTM D6413: Standard test method for flame resistance of textile (Vertical test)
• 16 CFR Parts 1615/1616: Standards for the flammability of children’s sleepwear

What is the Vertical Flammability Chamber? The vertical flammability tester is used to test the combustion performance of children's pajamas or decorative fabrics. Flame spread speed can be tested accurately by the combined use of a sealed stainless steel combustor, an observation window, and a standard burner. Equipped with different sample clips and accessory test packages, the vertical flammability tester can meet different test standards. It is easy to control the testing process through an automatic gas control system. Here take the ASTM D6413 standard as an example to introduce the vertical flammability test of fabrics. Regulating Instrument Adjust the gas pressure to 17.2±1.7KPa and ignite the flame and the flame height to 3mm, and ensure the shape of the flame will not change within 12s. Next, close the vent and open the solenoid valve to ensure that the flame height reaches 38mm
