GB/T 13477.13-2002

This standard specifies a test method for determining the adhesion and cohesion properties of building sealants when subjected to alternating cold stretching and hot compression cycles. 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 bond and structural integrity over time.
