Handling ZCC 2087.1 to ZCC 2087.4 acc. to DIN EN ISO 2409
Hold the cross-cut tester only at the handle.
The flexible cutting head should always move freely.
Never use your other hand or finger of the leading hand to add additional
pressure to the cutting head during testing.
Always pull the cross-cut tester, never push it.
If the panel is made of wood or a similar material, apply the cuts with an angle
of 45° to the direction of the grain.
Place the conditioned test panels on a rigid, flat surface to prevent any
•
deformation of the panel during the test.
Carry out the test at a temperature 23 ± 2 °C and relative humidity of 50 ± 5 %.
•
Remove any loose particles from the area of cutting. For suitable methods
•
refer to chapter 7.1 on page 14.
Carefully examine the cross-cut area and compare it with the classification
•
table in order to determine the cross-cut value.
Test at least on three areas on the panel.
•
Issue a test report.
•
Hold the ZCC 2087 with the blade vertical to
•
the test panel surface.
Make two successive cuts, the second cut
•
crossing the original one at 90°, generating
a lattice pattern. All cuts shall penetrate the
coating completely down to the substrate
surface. The indentation depth into the
substrate should be as low as possible.
