The Flame Flammability Tester is developed according to the NFPA 701 Method 2 and can be used for single or multi-layer fabrics. It’s used to determine the combustion performance of outdoor products, banners and many other products.
Application
The large-scale flame combustibility tester is primarily used to determine the burning performance of outdoor products, banners, and many other textile products. By simulating a fire environment, it evaluates the burning rate and flame spread of materials, providing crucial data to support the fire safety performance of products.
Standards
1. NFPA 701:Standard Methods of Fire Tests for flame propagation of textiles and films
2. UL 214:Test for flame-Propagation of fabrics and films
3. CAN/ULC S109:Flame tests of flame-resistant fabrics and films
Feature
1. Possesses a strong after-sales service team.
2. Able to handle various issues promptly and efficiently, relieving customers of any concerns.
3. A complete range of spare parts is available, eliminating the hassle of long lead times for ordering parts.
4. Keeps up with industry standard updates and provides testing instruments that meet the latest standards in a timely manner.

Test Procedures
Sample Preparation: Prepare samples according to the test standard requirements, ensuring that the size, shape, and quantity of the samples meet the test requirements.
Equipment Calibration: Check that all components of the equipment are functioning correctly, such as the ignition device and flow meter. Ensure that the gas supply system is in good working order.
Sample Installation: Secure the sample in the sample holder, ensuring its stability and vertical alignment during the test.
Gas Mixing and Supply: Adjust the flow rates of oxygen and nitrogen (if applicable) according to the test requirements, and supply the mixed gas to the combustion chamber after mixing in the mixing chamber. Ensure that the oxygen concentration of the mixed gas meets the test standard requirements (if applicable). For large-flame flammability testers, the focus is primarily on the supply of combustible gas and the stability of the flame.
Ignition and Timing: Turn on the ignition device to ignite the burner. Simultaneously start the timing device to record the burning time of the sample. When the sample burns to the specified length or the burning time reaches the preset value, turn off the ignition device and the gas supply system.
Data Recording and Analysis: Record all data during the test process, such as burning time and flame spread rate. Calculate the relevant parameter values according to the test standard requirements, and analyze and interpret the test results.
