Testing methods for paints-Part 5: Mechanical property of film-Section 7: Adhesion test (Pull-off method)

This Standard describes methods for determining the adhesion by carrying out a pulloff test on a single coating or a multi-coat system of paint, varnish or related product.
The test may be applied using a wide range of substrates. Different procedures are given according to whether the substrate is deformable, for example thin metal, plastics and wood, or rigid, for example thick concrete and metal plates.
NOTE 1 These test methods have been found useful in comparing the adhesion behaviour of different coatings. It is most useful in providing relative ratings for a series of coated panels exhibiting significant differences in adhesion.
NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
