Categoría Descripción

1 Abrasión total de una cara 2 Abrasión parcial de una cara

Mayor estabilidad

3 Abrasión total de ambas caras.

4 Abrasión total de una cara y parcial de otra

5 Abrasión parcial de ambas caras

Sin estabilidad (no estable)

Nota: “Parcial” significa que la abrasión no alcanza a cubrir el total de una superficie o cara.
