GB/T 41753-2022 specifies the test method for the durability of sealants under tension-compression cycling during artificial weathering, applicable to evaluating the aging resistance of various sealants. The standard simulates the synergistic effects of climatic erosion and mechanical stress in practical applications by subjecting cured sealant specimens to alternating cycles of compression and tension under artificially accelerated aging conditions. The core equipment includes a tensile testing machine, an accelerated weathering chamber, and measuring instruments. By controlling specific tension-compression amplitudes and aging cycles, the durability level is determined based on the failure state and light transmittance of the specimens. This test method provides a rapid and accurate reflection of the long-term service performance of sealants, offering a unified technical basis for quality control of sealing materials in construction, industrial, and other fields.
