GB/T 13477.12-2002 Determination of adhesion of focused building sealing materials after stretching-compression cycles at the same temperature. Standard specifies test equipment, such as stretching-compression Tester. Detailed preparation process of the specimen, the sealing material is subjected to multiple stretching and compression cycles at a specific temperature. After the cycle, the bonding performance is determined by observing the bonding status between the sealing material and the substrate, such as whether the bonding is firm, whether there is cracking or debonding phenomenon. The standard provides a basis for evaluating the long-term bonding Reliability of building sealing materials under constant temperature and displacement environment, and ensures the Stability and durability of building sealing projects.
