标准摘要
[中文适用范围]： 本文件规定了测定多孔建筑材料和产品吸湿吸附性能的两种替代方法： a) 使用干燥器和称量杯（干燥器法）； b) 使用气候室（气候室方法）。 干燥器法为参考方法。 本文件没有规定抽样方法。 本文件中指定的方法可用于确定特定温度和湿度下与空气平衡的样品的水分含量。 [外文原描述]： This document specifies two alternative methods for determining hygroscopic sorption properties of porous building materials and products: a) using desiccators and weighing cups (desiccator method); b) using a climatic chamber (climatic chamber method). The desiccator method is the reference method. This document does not specify the method for sampling. The methods specified in this document can be used to determine the moisture content of a sample in equilibrium with air at a specific temperature and humidity.
