The Cross-Cut test is a simple and practical method for evaluating the adhesion of coatings in single or multi-coat systems. At Dinsen, our quality inspection staff uses this method to test the adhesion of epoxy coatings on our cast iron pipes, following the ISO-2409 standard for accuracy and reliability.
Test Procedure
- 1. Lattice Pattern: Create a lattice pattern on the test sample with a specialized tool, cutting down to the substrate.
- 2. Tape Application: Brush over the lattice pattern five times in a diagonal direction, then press tape over the cut and let it sit for 5 minutes before removing it.
- 3. Examine the Results: Use an illuminated magnifier to closely inspect the cut area for any signs of coating detachment.
Cross-Cut Test Results
- 1. Internal Coating Adhesion: For Dinsen’s EN 877 cast iron pipes, the internal coating adhesion meets level 1 of the EN ISO-2409 standard. This requires that detachment of the coating at the cut intersections does not exceed 5% of the total cross-cut area.
- 2. External Coating Adhesion: The external coating adhesion meets level 2 of the EN ISO-2409 standard, allowing for flaking along the cut edges and at intersections. In this case, the affected cross-cut area can be between 5% and 15%.
