Hygrothermal performance of building materials and products — Determination of moisture adsorption/desorption properties in response to humidity variation

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.
