标准范围
This International Standard specifies a method for calculating the density of the water vapour flow ratein 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 systemby diffusion, with no contribution from airflow. It also assumes the use of homogeneous, isotropicinsulation materials so that the water vapour partial pressure is constant at all points equidistant fromthe axis of the pipe.This International Standard is applicable when the temperature of the medium in the pipe is above 0 °C.It applies to pipes inside buildings as well as in the open air.
