Definitions
1. what does gradation mean? Well, there are grades to a road and there are grades to steps. There are steep steps and shallow steps and so forth, and there are vertical poles. A vertical pole is not a gradient. You want a gradual grade up. That's what gradation means in our particular sense. (SH Spec 66, 6509CO9)
2. it means there are grades, as to a road, or steps which are a gradual grade up. (Aud 107 ASHO)
