FLAMMABILITY UL 94 V (50 W, 20 mm Vertical)
Objectives
This vertical flammability test is to determine the UL flammability rating v0 and flammability rating v1 and v2. The test evaluation includes the burning time, afterglow time, and the dripping of the combustion test sample.
Flammability Testing Equipment
UL94 Flammability test chamber
Pretreatment
- The relative humidity is 2 days/ 23℃/ 50%, and the hot air oven is 7 days/ 70℃.
- The flame height should be controlled to 20mm.
- The flame application time is 2×
- When the first burning time is over, the second flame application time begins.

FLAMMABILITY UL 94 HB (Horziontal Burning)
Objectives
The UL 94 horizontal burn test is a fire rating testing of material. Calculating the flammability rating for the burning rate of the specimen and taking the thickness into account.
Equipment
UL94 Flame test chamber
Pretreatment
- Control the experimental environment to 48 hours / 23°C / relative humidity.
- Adjust the flame height to 20mm.
- The ignition time is the 30s.
- If the flame front reaches the first mark within 30 s, the ignition should be stopped.
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 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 to prevent excessive smoke that may harm and pollute the environment.

Q: What is the meaning of 50W in the "50W (20 mm) Vertical Burning Test; V-0, V-1, or V-2?"
A: 50W, 500W refers to the burning power of the torch, which is generally designated by UL as the burning torch.
Q: Is the UL94 Horizontal & Vertical Flammability Testing Machine TF328 a combination of the Vertical Flammability Tester, 45 Degree Flammability Tester, and Horizontal Flammability Tester? Can it perform all three tests?
A: The UL94 Horizontal & Vertical Flammability Testing Machine TF328 is primarily used for horizontal and vertical burning tests, but it does not include the functionality for 45-degree burning tests. Therefore, the TF328 is a combination of horizontal and vertical burning testers, but it is not suitable for 45-degree burning tests.
If a 45-degree burning test is required, a specialized 45-degree flammability tester is typically needed.
Q: Why does the igniter fail to ignite the sample or the flame extinguishes quickly?
A: This issue can occur due to the following reasons:
Gas Pressure and Flow Issues: Ensure that the gas supply is consistent and the pressure is at an appropriate level. Either too low or too high pressure can affect ignition.
Igniter Problems: Check if the igniter is clogged or damaged. Clean or replace the igniter as necessary.
Distance Calibration: Ensure the distance between the igniter and the sample is within the standard range. Too close or too far can affect stable ignition.
Q: What should I do if the sample is not positioned horizontally during the UL94 flammability test?
A: Ensure that the sample is securely fixed at a 45-degree angle during the flammability test.
Q: How can I ensure accurate flame contact time during the UL94 test?
A: To achieve accurate flame contact time, carefully control both the flame duration and the distance between the flammability tester and the sample.
Q: What could cause the after-flame time to be too long?
A: If the after-flame time is too long, verify whether the material meets the flame retardant requirements for V-0 or V-1 classifications. Longer after-flame times might indicate a lower flame retardancy.
Q: How can I deal with inconsistent results in repeated UL94 tests?
A: Perform multiple tests and calculate the average result to improve the reliability of the final outcome.
Q: What are the standards for flammability test levels for plastics?
A: (1) GB/T2408-2008 Determination of Flammability Properties of Plastics by Horizontal and Vertical Methods
(2) GB/T2406.2-2009 Plastics: Determination of burning behaviour by oxygen index method.
(3) American Standard UL94 Flame Retardant Grade
Others are GB/T8924-2005 "Test Method for Combustion Performance of Fibre Reinforced Plastics Oxygen Index Method", ASTM D2863, GB/T 5169.16, GB/T 5169.17, GB 4943.1 and so on.
Among them, 94-V is UL94 vertical combustion test classification standard, mainly divided into V0, V1, V2 three levels (GB2408-2008 vertical test is also V0, V1, V2 three levels), UL94 and 5VA and 5VB two levels, is also the highest level of flame retardant plastics. Different levels require different technical indicators.
