GB/T 13477.22-2022 specifies the determination method of curing characteristics of building sealing materials. The standard specifies the technical requirements of test equipment, such as curing time tester, and details the preparation process of the specimen. The curing characteristics of sealing materials are evaluated by observing the curing changes of sealing materials over time under different conditions, including indicators such as curing time and degree of curing. This helps to understand the performance evolution of sealing materials from construction to final molding, providing a scientific basis for building construction arrangement and quality control, ensuring that sealing materials play an excellent sealing effect at the right time, and ensuring the smooth implementation of building sealing projects.
