Assessment and evaluation of the cross-cut characteristic value

Perfectly smooth cut edges, without chipping.

A perfectly cleanly imaged cross-cut screen without any coating loss.

             0

Slight chipping at the intersections of the grid lines

chipped area not greater than 5 % of the grid cut area.

             1

Spalling along the cut edges and/or at the intersections of the grid lines

chipped area greater than 5 % but not greater than 15 % of the grid cut area.

             2

Chipping along the cut edges and/or of squares (whole + partial)

chipped area greater than 15 % but not greater than 35 % of the grid cut area.

             3

Chipping along the cut edges and/or of squares (whole + partial)

chipped area greater than 35 % but not greater than 65 % of the grid cut area.

             4

Spalling whose coating loss is significantly more than 65% of the total grid cut area,

and which therefore can no longer be assessed with a characteristic value of "4".
