GB/T 20312-2006
ActiveHygrothermal performance of building materials and products - Determination of hygroscopic sorption properties
建筑材料及制品的湿热性能 吸湿性能的测定
Application Summary AI generated
This standard specifies a test method for determining the moisture absorption and desorption properties of building materials and products under controlled temperature and humidity conditions. It is applied in the construction industry to evaluate how materials like insulation, wood, or gypsum boards interact with ambient moisture, which is critical for predicting thermal performance, durability, and indoor air quality. The standard is used by material manufacturers, testing laboratories, and building designers to ensure products meet hygrothermal performance requirements for specific climates or building applications.
