Multi-purpose flammability tester is an instrument used to test the combustion properties of materials under flame. It measures the combustion properties of a material, including parameters such as ignition time, burn time, smoke generation, and heat release. It is commonly used to evaluate the combustion properties of materials under fire conditions to determine their impact on fire safety.
Typically, the Multi-purpose flammability tester consists of a combustion chamber, an ignition system, a heat release meter, a smoke density meter, a gas analyzer, and a data acquisition system. In the test, the material to be tested is placed in the combustion chamber, ignited by the ignition system, and the various parameters generated during the combustion process are measured.
The Multi-purpose flammability tester can perform many types of combustion tests to obtain information about the combustion behavior of the material under different conditions. Common tests include:
1. Flammability test: This test is used to evaluate the burning behavior of a material under contact with an open flame or fire source. It measures parameters such as the burning rate, flame propagation rate, flame extension and fire products of the material.
2. Smoke product test: This test is designed to evaluate the amount of smoke and smoke toxicity released by a material during combustion. It can measure the optical density of smoke, particle concentration and smoke composition.
3. Heat release test: This test is used to measure the heat released by the material during combustion. It can evaluate the rate of heat release and the total heat release of the material during a fire.
4. Flame propagation test: This test is designed to evaluate the flame propagation performance on a material. It measures the rate of flame spread on the surface of the material and the duration of the flame burn.
Multi-purpose flammability tester usually uses standardized test methods and equipment to ensure the accuracy and comparability of test results. The results of these tests are important for assessing the fire safety of materials in construction, automotive, aerospace and other fields.
