The "GB/T 31934-2015 Methods for the Determination and Calculation of Heat Storage of High Radiation Coatings" standard specifies the measurement and calculation methods of heat storage of high radiation coatings, including terminology, definitions, test methods, materials, instrumentation and equipment, sample preparation and requirements for measurement reports. Heat accumulators suitable for a variety of fired refractory-based high radiation coatings. The standard describes in detail the definition of high radiation coatings and the calculation method of heat storage, ensuring the accuracy and conformity of the test. The standard also refers to the sample preparation method and numerical revision rules for shaped refractory products, providing complete testing and calculation guidance.
