ActiveTest method for building sealants－Part 13：Determination of adhesion/cohesion properties at variable temperatures
建筑密封材料试验方法 第13部分：冷拉-热压后粘结性的测定
Application Summary AI generated
This standard specifies a test method for determining the adhesion and cohesion properties of building sealants after being subjected to cyclic cold stretching and hot compression. It is applied in the construction industry to evaluate the durability and performance of sealants used in joints and gaps of building facades, windows, and curtain walls under varying temperature conditions. The test simulates real-world thermal movements to ensure sealants maintain their bonding integrity in extreme climates.
