Method B (Lattice
)
Cross-cut
DIN EN ISO 2409
ASTM D3359
0
The edges of the cuts are
completely smooth; none of the
squares of the lattice is detached.
5B
The edges of the cuts are
completely smooth, none of the
squares of the lattice is detached.
Percent area removed: 0 % - none
1
Detachment of small flakes of the
coating at the intersections of the
cuts.
A cross-cut area not greater than 5
% is affected.
4B
Small flakes of the coating are
detached at intersections, less than
5 % of the area 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.
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.
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.
2B
The coating has flaked along the
edges and on parts of the squares.
The area affected is 15 to 35 % of
the lattice.
4
The coating has flaked along the
edges of the cuts in large ribbons
and/or some squares have
detached partly or wholly.
A cross-cut area greater than 65 %
is affected.
1B
The coating has flaked along the
edges of cuts in large ribbons and
whole squares have detached.
The area affected is 35 to 65 % of
the lattice.
5
Any degree of flaking that cannot
even be classified by classification
4.
0B
Flaking and detachment worse than
classification 1B.
