GB/T 22459.6-2022 specifies the test method for determining the water content of pre-mixed refractory mortars, applicable to ready-to-use pre-mixed refractory mortars, providing a basis for their construction performance and quality control. The standard clarifies the test principle, sampling procedure, and result calculation requirements. The core instruments used include a balance, drying oven, desiccator, and ceramic or glass containers. The process involves first drying the container to constant weight, then placing a 50g to 100g sample into the container and drying it at 110℃ ± 5℃ until constant weight is achieved. After cooling, the mass difference is measured and calculated, with the average of two tests taken as the water content result, ensuring accurate and reliable detection data.
