GB/T 41879-2022 《Plastics—Burning behaviour—Intermediate-scale fire-resistance testing of fibre-reinforced polymer composites》 Related products

GB/T 41879 - 2022 specifies a medium-sized fire resistance test method for the combustion performance of fiber-reinforced polymer composites in plastics. The standard details the construction of test equipment, including fire sources, combustion tanks, etc. Clarify the preparation of composite samples, such as size and shape requirements. Standardize the test process, such as ignition time, observation record points. Through this test, the fire resistance characteristics of materials in medium-scale fire scenarios are accurately evaluated, and their applications in areas with fire protection requirements such as buildings and transportation are provided with reliable performance judgment basis.
