PREN 927-10-2017 Paints and varnishes - Coating materials and coating systems for exterior wood - Part 10: Resistance to blocking of paints and varnishes on wood
This European Standard specifies a test method for determining@ under standard conditions@ whether a single-coat film or a multi-coat system of paints and varnishes on wood after a specified drying period is sufficiently dry to avoid damage when two painted surfaces or one painted surface and another surface are placed in contact under pressure and subsequently separated. The method is intended to simulate the conditions when painted articles come into contact which each other. In comparison to EN ISO 9117-2@ the conditioning and parameters which influence the behaviour of wood coatings are more specific. NOTE In some countries@ the test is called a ??block or blocking resistance?? test.
