This standard specifies simple calculation methods for the following:a) The internal surface temperature of building components or members where mold can grow is given by the internal temperature and relative humidity. This method can also be used to assess the risk of surface condensation problems on other internal surfaces. b) Used as a risk assessment of internal condensation due to water vapor diffusion, this method does not take into account a number of key physical phenomena, such as: .- Change in material properties depending on moisture content - Capillary suction and moisture movement within the material - Air movement from inside the building to the components through cracks (gaps) or spaces - Hygroscopic capacity of the material. As a result, this method reduces the effect of these phenomena. Applies where negligible.c) What is the time for moisture to be absorbed between two layers that exhibit high resistance to moisture permeation when dried from any source and the risk of internal condensation occurring within the component during drying?
