Hygrothermal performance of building equipment and industrial installations. Calculation of water vapour diffusion. Cold pipe insulation systems Ingestion-build-53008 BS EN ISO 8253-2 specifies1 Scope This International Standard specifies a method for calculating the density of the water vapour flow rate in cold pipe insulation systems, and the total amount of water diffused into the insulation over time. The calculation method presupposes that water vapour can only migrate into the insulation system by diffusion, with no contribution from airflow. It also assumes the use of homogeneous, isotropic insulation materials so that the water
