ActiveTest method for building sealants—Part 19：Determination of change in mass and volume
建筑密封材料试验方法 第19部分：质量与体积变化的测定
Application Summary AI generated
This standard specifies a laboratory test method for measuring the mass and volume change of building sealants after exposure to heat, ultraviolet light, or water immersion. It is applied in the construction industry to evaluate the dimensional stability and potential shrinkage or swelling of sealants used in joints, windows, and curtain walls. The test ensures sealant performance under environmental stress, helping to prevent adhesive failure or joint deformation in building applications.
