This Standard specifies methods for carrying out a pull-off 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 specified according to whether the substrate is deformable, for example thin metal, plastics and wood, or rigid, for example thick concrete and metal plates. For special purposes, the coating may be applied to a test cylinder and, in this case, a method for determination of the coating thickness shall be agreed between the interested parties. The test result is the minium tensile stress necessary to break the weakest interface (adhesive failure) or the weakest component (cohesive failure) of the test assembly. Mixed adhesive/cohesive failures also occur.
