Abstract
This Technical Specification 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 resist damage when two painted surfaces or one painted surface and another surface are placed in contact under pressure. The method is intended to simulate the conditions when painted articles are in contact which each other. In comparison to EN ISO 9117-2, Paints and varnishes ? Drying tests ? Part 2: Pressure test for stackability the conditioning and parameter which influences the behaviorbehaviour of wood coatings are more specific.NOTE In some countries, the test is called a ?block resistance? test.
