In order to perform satisfactorily, coatings must adhere to the substrates on which they are applied. In practice, four different test procedures are used to assess the resistance of paints and coatings to separation from substrates.
This test method specifies a procedure for assessing the resistance of paints and coatings to separation from substrates when a right angle lattice pattern iscut into the coating, penetrating through to the substrate.
The method may be used for a quick pass/fail test. When applied to a multi-coat system, assessment of the resistance to separation of individual layers of thecoating from each other may be made.
