The GB/T 3007-2006 standard focuses on the determination of water content of refractory materials. It stipulates the test method for determining the water content of refractory materials, covers the specific operation process such as drying method, clarifies the required instruments and equipment, such as drying oven, Balance accuracy requirements, etc., and also regulates the selection of samples and the preparatory steps. The standard provides a unified water content detection standard for the production and use of refractory materials, which helps to control the mass of products, ensure the stable performance of refractory materials in high temperature environments, and ensure the safe and efficient operation of related industrial production.
