9 Overview – Cross-cut classification
Classification of test results
Cross-cut
According to
DIN EN ISO 2409
0:
The edges of the cuts are
completely smooth; none of
the squares of the lattice is
detached.
1:
Detachment of small flakes
of the coating at the
intersections of the cuts. A
cross-cut area not greater
than 5 % is affected.
2:
The coating has flaked
along the edges and/or at
the intersections of the
cuts. A cross-cut area
greater than 5 %, but not
greater than 15 % is
affected.
3:
The coating has flaked
along the edges of the cuts
partly or wholly in large
ribbons, and/or it has
flaked partly or wholly on
different parts of the
squares. A cross-cut area
greater than 15 % but not
greater than 35 % is
affected.

According to
ASTM D3359
5B
The edges of the cuts are
completely smooth, none
of the squares of the
lattice is detached.
Percent area removed:
0 % - none
4B
Small flakes of the
coating are detached at
intersections, less than
5 % of the area is
affected.
3B
Small flakes of the
coating are detached
along edges and at
intersections of cuts. The
area affected is 5 to 15 %
of the lattice.
2B
The coating has flaked
along the edges and on
parts of the squares. The
area affected is 15 to 35
% of the lattice.
