GB/T 13477.14-2002 focuses on the determination of the adhesion of building sealing materials after immersion in water and tensile-compression cycle. The standard stipulates that the sealing material specimen is first immersed in water to simulate a humid environment, followed by a tensile-compression cycle to simulate the construction displacement working conditions. Detailed description of the test equipment, specimen preparation and the operation process of each stage. Reliability under complex practical conditions is evaluated by detecting the bonding performance of the sealing material after the cycle, such as changes in bond strength and whether it is debonded. Provide a key mass detection basis for the application of building sealing materials in long-term humid and displaced scenarios, and ensure the lasting effectiveness of sealing engineering.
