GB/T 14402-2007 《Reaction to fire tests for building materials and products - Determination of the heat of combustion》 Related products

GB/T 14402 - 2007 is used to determine the combustion calorific value of building materials and products. The standard clarifies the measurement principle, specifies the technical requirements and calibration methods of calorimeters and other instruments and equipment, and details the preparation, weighing and testing steps of the sample, including placing the sample in an oxygen bomb for combustion and measurement of heat changes. Through this standard, the combustion calorific value of materials can be accurately obtained, providing key data for the construction industry to evaluate the risk of material fire and select safe building materials, helping to improve the level of building fire safety, and promoting the industry to choose low combustion calorific value materials.
