1 Scope
This European Standard specifies a method for determining the liquid water permeability
of coatings, coating systems and related products, intended for exterior masonry and
classification according to EN 1062‑1.
The method is applicable to coatings and coating systems on porous substrates such
as brick, concrete and renderings.
A liquid water permeability w of more than 0,5 kg/(m2 x h0,5) will not be accurately quantified by the test method described in this standard.
