NF EN ISO 3678-1995 《Paints and varnishes - Print-free test.》 Related products

The NF EN ISO 3678:1995 standard specifies the non-imprint test method for Paints and varnishes. This test is designed to assess whether coatings leave imprints under specific pressures, in particular for testing the imprint resistance of Coating surfaces when subjected to pressure or in contact with objects. During the test, the surface of the coating sample is subjected to a specific pressure and contacted by a standard hard object or tool to observe whether visible imprints or surface damage are produced. The standard applies to all types of Coatings, especially for applications in environments where the surface is required to remain flat and nondestructive, such as furniture paintings and automotive coatings. The non-marking test helps to evaluate the durability and practicality of the coating, ensuring that it is not susceptible to damage from external forces in daily use, thereby enhancing the market competitiveness of the coating.
