An empirical test to establish liability. This can be applied as a so-called 'yes/no' test or as a six-step grading test, which depends on the circumstances.
Specimens produced specifically for this purpose and also already finished items may be used for the test itself.

Procedure: On a painted substrate, 6 parallel cuts are applied to the substrate. Then, six cuts are made at right angles in a crisscross pattern over the top of the substrate - thus creating the grid that gives the test its name. It is important that the spacing between the cuts is always the same (depending on the substrate and the coating thickness).

Layer thickness Spacing
0 to 60 µm 1 mm for hard substrates
0 to 60 µm 2 mm for soft substrates
61 to 120 µm 2 mm for hard and soft substrates
61 to 120 µm 3 mm for hard and soft substrates

Table: Cutting distance for different coating thicknesses (according to EN ISO 2409)
