This document specifies three methods for determining the adhesion by carrying out a pull-off test on a single coating or a multi-coat system of paint, varnish or related product.


These methods include:


—    method A: using two dollies, suitable for testing both rigid and deformable substrates;


—    method B: testing from one side only, using a single dolly, suitable for rigid substrates only;


—    method C: using dollies, one as a painted substrate.


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.
