This document specifies a test method for assessing the discoloration of coatings on wood by tannin staining
due to wood extractives. Bleeding of wood extractives can be assessed in two phases, after coating
application and after cyclic climate exposure. It is allowed to carry out the assessment only after coating
application without additional climate exposure. A qualification of colour differences that can be attributed to
bleeding of extractives, low opacity of the coating film or general yellowing in climate exposure is included.
This document does not specify values of colour differences that can be tolerated and it is not applicable to
staining of knots.
