Textile vertical burning test experiment and principle
Vertical combustion test test standard: ASTM D6413, DOC-FF 3/71, CALIF TB-117, GB/T5455, CPAI-84 Test principle: Use the flame generated by the specified igniter to ignite the center of the bottom edge of the sample in the vertical direction. After the specified ignition time, measure the continuous burning time, smoldering time and damage length of the sample. The composition of the instrument and equipment and the coordination of various parts: 1. The test box body, the side and top of the box body are provided with standard ventilation holes. The box door should be embedded with transparent refractory glass so that the tester can observe the burning condition of the sample. 2. The sample holder and its fixing device. The sample holder is provided with barbs, which are hung on the sample holder bracket on the upper part of the box body, and the middle part of the box body is also provided with a fixing device to ensure that the sample remains in the vertical direction. 3. Ignition timing system. The ignition timing system of the instrument is independent of the test box. Different standards, the control of ignition time is different. One is to control the gas supply time. After the time specified in the standard is reached, the gas is turned off and the external source combustion stops. One is to move the flame position. After the standard ignition time, the flame position is far away from the sample. 4. The timing device is to manually start the timing, test this to observe the surface state of the fabric, and press the switch to start timing. Test process: Take GB/T 5455-2014 as an example to introduce the test process of vertical combustion test. 1. Close the front door of the test chamber, open the gas supply valve, light the igniter, and adjust the flame height. After burning for a certain period of time, extinguish the flame (exclude the air in the pipe). 2. Load the dried sample into the fixture, and the sample should be as flat as possible. Hang the upper end of the sample holder on the support, and the side is fixed by the sample holder fixing device. 3. Close the door and light the igniter. After the flame is stable, move the flame to just below the sample. 4. After the ignition time, remove the igniter, turn on the timer, and record the continued combustion time and smoldering time. Record the burning status of the sample at any time. 5. Turn on the fan or fume hood to remove the smoke. 6. Open the door of the box, take out the sample, and hang a heavy hammer on one end of the fabric to test the damage length. The test method is shown in the figure. Fold a straight line along the highest point of the damaged area along the length of the sample, and then hang the selected weight on the lower end of the sample, about 6mm from the bottom and the sides of the sample, and then slowly lift it up by hand. On the other side of the lower end of the sample, let the heavy hammer hang in the air, then put it down, measure and record the length of the sample torn, which is the damaged length, accurate to 1mm. Note: 1. The burning of textiles may produce smoke and toxic gases that affect the health of operators, and test personnel need to wear gas masks. The test can be completed in a fume hood. Smoke and smoke should be removed after each test. 2. The ventilation system should be closed when the sample is burning to avoid affecting the test results. 3. When testing fabrics made of fusible fibers, if the test sample has melt droplets during the burning process, 10mm thick absorbent cotton should be laid flat on the bottom of the test box, and whether the absorbent cotton burns or smolders should be recorded. .

Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
