5B The edges of the cuts are completely smooth; none of the squares of the lattice is detached.

切口的边缘很光滑，没有方格分离

4B Small flakes of the coating are detached at intersections; less than 5 % of the area is affected.

在方格交叉处有很小的涂层分离，少于5%的区域被影响。

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.

沿着方格边缘部分和方格交叉处有一小部分的薄片分离。有5%-15%区域的方格被影响。 2B The coating has flaked along the edges and on parts of the squares. The area affected is 15 to 35 % of the lattice.

沿着方格边缘和一部分的方格区域有一小部分薄片分离。有15-35%区域的方格被影响。 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.

涂层沿着方格的边缘部分有很大的带状分离，整个方格被分离了。有35-65%区域的方格被影响。

0B Flaking and detachment worse than Grade 1. 分离比等级1更严重。
