DIN EN ISO 4624-2003 《Paints and varnishes; pull-off test for adhesion (ISO 4624:2002)》 Related products

The DIN EN ISO 4624-2003 standard specifies a method for determining Paints and varnish adhesion by pull-off test. This test is suitable for single or multi-layer coating systems and assesses the adhesion of coatings by measuring tensile stress in the direction perpendicular to the substrate. The standard provides test procedures for a variety of substrates, including deformable substrates (e.g. thin metal, plastic and wood) and rigid substrates (e.g. thick concrete and sheet metal). Test results are influenced by a number of factors such as coating system Mechanical Properties, substrate properties, construction methods, drying conditions, etc., providing a relative rating for coating adhesion.
