《GB/T 20312-2006建筑材料及制品的湿热性能吸湿性能的测定》由TC191（全国绝热材料标准化技术委员会）归口，主管部门为中国建筑材料联合会。
本标准规定了测定多孔建筑材料及制品吸湿性能的两种可供选择的方法，干燥气法和气候箱法。本标准没有规定抽样的方法。本标准规定的方法也可测定试样的含湿率。

Scope

This standard specifies two alternative methods for determining the moisture absorption properties of porous building materials and articles. - Desiccator method, using a desiccator and a weighing cup; - Climate chamber method, using a climate chamber. The desiccator method is the benchmark-tip method. The method specified in this standard can also be used to measure the moisture content of the sample when it reaches moisture equilibrium under the specified temperature and humidity.
