ISO 2409:2007描述了一种测试方法，用于评估当直角晶格图案被切割到涂层中，穿透到基底时，涂料涂层与基底分离的阻力。除其他因素外，通过该经验试验程序测量的性能取决于涂层与前一涂层或基材的附着力。然而，该程序不应被视为测量附着力的方法。所述方法可作为通过/失败测试，或在适当情况下，作为六步分类测试。当应用于多层涂层系统时，可评估涂层各层之间的抗分离性。试验可在成品和/或特殊制备的试样上进行。该方法不适用于总厚度大于250微米的涂层或纹理涂层。

ISO 2409:2007 describes 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 measured 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.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 may be made.The test can be carried out on finished objects and/or on specially prepared test specimens.The method is not suitable for coatings of total thickness greater than 250 micrometres or for textured coatings.
