Scope according to ISO 2409 (Chapter 1):

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.

Scope according to ISO 2409 (Chapter 3, 5, 6):

  • General
  • Cutting tool
  • Guiding and spacing edges
  • Viewing lens
  • Test panels
  • Substrate
  • Preparation and coating
  • Drying
  • Thickness of coating
  • Cutting the coating using the manual procedure
  • Cutting the coating using a motor-driven tool
  • Repeatability limit, r
  • Reproducibility limit, R
