GB/T 13477.19-2017 provides specifications for the determination of mass and volume changes of building sealing materials. It details the requirements of test equipment, such as high-precision Balance, volume measurement measuring tools, etc. Clarify the preparation process of sealing material specimens, and place the specimens in a specific environment, such as different temperatures Humidity or chemical media. Before and after the specified time period, accurately measure the mass and volume of the specimen, and calculate the rate of change. This is used to evaluate the sealing material Stability, providing key test data for its long-term performance in complex building environments, and helping to ensure the durability and Reliability of sealing projects.
