The orthogonal impact of a Newtonian liquid drop impact onto dry solid surfaces is studied. The focus was placed on finding the possible outcomes of the drop impact and the time evolution of the impact process. A new phenomenological classification differentiates between six possible outcomes. In order to be able to identify the influencing parameters, changes of drop diameter, impact velocity, surface tension, viscosity, advancing and receding contact angles, roughness amplitude and wavelength have been made. The influences of these impact parameters on the various phases of the impact process has been investigated.
