GB/T 13477.10-2002

This standard specifies a test method for determining the tensile properties of building sealants when subjected to a constant extension. It is applied in the construction industry to evaluate the adhesion and cohesion performance of sealants used in joints and gaps in building structures, such as those in curtain walls, windows, and expansion joints. The test is critical for quality control and material selection to ensure sealants can withstand long-term static deformation without failure.
