Specific properties that were tested included compression strength, hardness, density, magnetic properties, and the capability to drill and tap melted regolith.
Hardness Testing. The scale used in this experiment was superficial HR45N.
Additionally, more accurate hardness testing via the Vickers or Knoops methods would help in evaluating the potential failure modes of the material when it might affect mission safety.
