标准范围

This document specifies a method for determining the water-vapour transmission properties of 
coatings of paints, varnishes and related products.
It supplements ISO 12572. As far as possible, the procedure, the definitions and the calculations 
have been taken over from ISO 12572. ISO 12572 can be consulted, if necessary, to obtain a better 
understanding of the procedure specified in this document.
Water-vapour transmission rates of more than 680 g/(m² ⋅d) (i.e. water-vapour diffusion-equivalent air 
layer thicknesses, s_d , of less than 0,03 m) are not accurately quantified by the test method described in 
this document.
