This International Standard specifies a test method for assessing the resistance of paint coatings
to separation from substrates when a right-angle lattice pattern is cut into the coating, penetrating
through to the substrate. The property determined by this empirical test procedure depends, among
other factors, on the adhesion of the coating to either the preceding coat or the substrate. This procedure
is not to be regarded, however, as a means of measuring adhesion.
Where a measurement of adhesion is required, the method described in ISO 4624[1] may be used.
The method described may be used either as a pass/fail test or, where circumstances are appropriate,
as a six-step classification test. When applied to a multi-coat system, assessment of the resistance to
separation of individual layers of the coating from each other can be made.
The test can be carried out on finished objects and/or on specially prepared test specimens.
Although the method is applicable to paint on hard (e.g. metal) and soft (e.g. wood and plaster) substrates,
these different substrates need a different test procedure.
The method is not suitable for coatings of total thickness greater than 250 µm or for textured coatings.
