AbolishedThermal insulating products for building applications―Determination of long-term water absorption by immersion
建筑用绝热制品 浸泡法测定长期吸水性
Application Summary AI generated
This standard specifies a test method for determining the long-term water absorption of thermal insulating materials used in buildings by immersing specimens in water for a defined period. It is applied in the construction industry to evaluate the durability and moisture resistance of insulation products like mineral wool, EPS, or XPS boards, particularly for applications in foundations, roofs, or below-grade walls where prolonged water exposure is expected. The test results help engineers and specifiers assess material performance under wet conditions to ensure thermal efficiency and structural integrity over time.
