GB/T 5464 - 2010 is used to test the non-combustibility of building materials. It makes strict regulations on the preparation of samples, covering size, quantity and other requirements to ensure that the samples can represent the characteristics of the material. Detail the specifications and performance of non-combustibility test furnaces and other equipment. During operation, specify key parameters such as heating rate and test duration. Through this standard test, it is possible to accurately determine whether the material is non-combustible. This is essential for the selection of building materials and the design of building fire protection. It provides a scientific basis for ensuring building fire safety and helps the construction industry to screen safe and reliable materials to reduce the risk of fire.
