Thermal insulating products for building equipment and industrial installations - Determination of water vapour transmission properties of preformed pipe insulation (ISO 12629:2022)

This document specifies the equipment and procedure for determining the water vapour transmission properties in the steady state under specified test conditions for test specimens of preformed pipe insulation. It is applicable to thermal insulating products. It is intended to be used for homogeneous materials (see NOTE below) and for products which can have integral skins or adhered facings of some different material. NOTE      A material is considered to be homogeneous in terms of mass distribution if its density is approximately the same throughout, i.e. if the measured density values are close to its mean density.
