ISO 24353:2008规定了根据湿度变化确定建筑材料吸湿/解吸性能的试验方法。ISO 24353:2008还定义了建筑材料的吸附/解吸效率，测量为从给定空间移动到不同相对湿度和相同温度的另一个空间的试样质量变化。 在单次循环和多次循环的条件下测量材料的吸湿/解吸性能。

ISO 24353:2008 specifies a test method for determining moisture adsorption/desorption properties of building materials in response to humidity variation. ISO 24353:2008 also defines the adsorption/desorption efficiency of building materials, measured as the change in mass of a specimen moved from a given space to another one of different relative humidity and equal temperature. Moisture adsorption/desorption properties of materials are measured under conditions of a single cycle and several cycles.
