ActiveThermal 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 building applications by immersing specimens in water. It is applied in the construction industry to evaluate the durability and moisture resistance of insulation products, such as mineral wool, expanded polystyrene, or polyurethane foam, under prolonged wet conditions. The standard is used by manufacturers, testing laboratories, and quality control engineers to ensure insulation performance in building envelopes, roofs, and foundations exposed to groundwater or persistent moisture.
