This document specifies two alternative methods for determining hygroscopic sorption properties of porous building materials and products:<\/p>\n

    \n
  1. \n

    using desiccators and weighing cups (desiccator method);<\/p>\n<\/li>\n

  2. \n

    using a climatic chamber (climatic chamber method).<\/p>\n<\/li>\n<\/ol>\n

    The desiccator method is the reference method.<\/p>\n

    This document does not specify the method for sampling.<\/p>\n

    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.<\/p>\n
