ISO 4624 Paints and Varnishes - Tensile Test Standard for Adhesion

EUROLAB laboratory provides testing and compliance services within the scope of ISO 4624 standard. ISO 4624 specifies three methods for determining adhesion by performing a tensile test on a single coating or a multi-layer system (ie, one dolly or two dollys on a painted panel and one as a painted substrate).

These test methods have been found useful in comparing the adhesion behavior of different coatings. It is most useful in providing relative ratings for a range of coated panels that exhibit significant differences in adhesion.

The test can be performed using a wide variety of substrates. Different procedures are given depending on whether the substrate is deformed, for example thin metal, plastic and wood, or hard, for example thick concrete and metal plates. To avoid degradation of the substrate during the tensile test, it is common to use a sandwich construction. For example, for special purposes, the coating can be applied directly to the face of a test car.
